Four, and constantly improve the management efficiency of Internet culture

In recent years, we insist on grasping developing, intensifying management, management development, better results than. But we must awake to see, we still exist in the management of a weak link, some management responsibility implementation lackadaisical, measures, for some unsatisfactory results, a new problem in new situation of some research, new technology and new business with no way, many problems still no crack. Management, How to further improve ideological understanding, unified management, improve the level of management, it will not only dare to management and good management, performance management, cover is we must seriously study and solve the important topic.

One is to management. To fundamentally solved the existing problems in the management of the Internet, or by strong legal system to add. To intensify the administration according to law, the administration of Internet, promote legalization, go on gradually standardized track. First, the law breakers and punished. China has now established a about Internet management laws and regulations, but in actual work, the existing laws and regulations is not implemented well, obviously some illegal behavior sometimes get timely and effectively stop and check. We must attach the enforcement of the management of existing laws and regulations, and strengthen the management of network for each extension and judicial interpretation work, intensify law enforcement, implement the enforcement responsibility, law enforcement, strengthen body and comprehensive enforcement, accomplish truly enforced law breakers, and punished. Second, according to law and other management means tube combined. Laws and regulations on the Internet are mandatory, plays a main role in management, but the laws and regulations also needs to have a perfect process, and laws and regulations can solve all the problems in network management, also need other auxiliary. The management of the Internet to insist, except for comprehensive management according to the laws, but also by the administrative intervention, economic sanctions, public appraisal, layered orientation means such as multiple tube, exquisite strategy management method, emphasize management effectiveness. To study the good management experience and practice, combining the actual network culture development of the province, the actual situation of the network for our cultural management mode. Third, strengthen the development of new technology, and provide technical support for the management of Internet. The encryption, including the Internet filtering, sealing, intelligent search, public opinion monitoring and warning technology etc, to ensure safety on the net, net information on major issues of major events, and disposal capacity.

Two is to strengthen self-discipline and public supervision and management pattern, form socialization. To strengthen network culture, rely on the tube is obviously not the power of social each aspect, need to play the role, rely on the whole society to find and solve problems, forming the government management, self-discipline and public supervision and management pattern. First, give full play to the role of industry organization. The association has been established in this industry, and to give full play to the function of the organization, support them actively participate in the construction and management of network culture. To build research network information service enterprise culture, made the system of public credit to access services, based carriers, ask for the contents of the social responsibilities, the business situation assessment and contents of social public to guide them, since the law, and shall operate the law. Second, give full play to the role of public supervision. The public is the Internet users, and good supervisor. The Internet has been established in illegal and bad information report in heart, to bring into full play, and accept the public reporting, timely to law enforcement agencies reflect, implement the system of reporting prize excitation, publicize regularly studio 14 battery accept and investigate conditions. Third, daxing network of civilization. Daxing nets winding of civilization, the requirement to the site contents, Internet access to civilization. Website to handle good economic benefit and social benefit and social responsibility, and don’t disseminate various illegal and bad information, on the net friend uploading information necessary to delete the vulgar and sealing, not bad information website for illegal connection, To speed up the popularization and the classification, filtering software technology, effectively shielded bad online and harmful information, for teenagers and build green security network space. Education should guide the majority of Internet users, civilized Internet, do not upload and download, browsing and release, illegal and bad information and communication, the Internet is not spread rumors are not online stories. To strengthen the basic knowledge of Internet users for popularizing, strengthen the network moral education system and network collaterals, civilization, the Internet website, promote to form good habits. DE network straight

Three is to play a good role of existing management system. The management of the Internet, the central province and a series of instructions in spirit, no.62 [2007] 16th the relevant publicity culture department of the information service network culture industry departments, and emphasizes the Internet industry competent and supervision door is network culture information service management department, further reiterate the who’s in charge who are responsible for the management and the principle of territoriality. The department of management responsibilities and tasks are very clear, now is the key to establish and perfect the system of machine, implement the relevant work responsibilities, good the existing management system, the function and responsibility to appear, avoid negative mutual dispute over trifles, responsibility stools phenomenon. Cities, the enterprises and the site, to enhance the management of the extreme importance of understanding, strengthen their leadership in the work of management, in their policies and provide guarantee for aspects of existing management measures to guarantee the implementation of the existing in the management of responsibility not implement, improper management, strict accountability system. Internet network management involves publicity and education, broadcasting and television, public security and communications, etc, to strengthen the coordin HP 540 battery department, unity, communication, management work pace.

The first chapter fully understanding to strengthen network culture construction and management of the utmost importance

In recent years, as the Internet technology, the rapid development of Internet technology and combination of social and cultural life increasingly close, out of the new cultural form, one of China’s Internet culture and the political, cultural, social and international exchanges, national security has been extremely profound influence and important. The 17th national congress of the party, “the report should strengthen the construction and management of network culture, creating a good network environment. We must take a positive attitude, and the spirit of innovation, develop and communication network, the construction of Internet, practical usage and management.

Currently operating nuclear power plants have been built, the basic working principle is: nuclear fuel (such as uranium -235) in the reactor nuclear fission chain reaction, a lot of heat generated by the heat carrier agent (water or gas) to bring out, in the steam device in the heat to the water, the hot water into steam to drive turbine power generation. Heat carrier agent, heat to water, then pump it back to the endothermic reactor, loop applications continue to put the nuclear reactor that could lead to the release out. Nuclear reactor and steam generator in the equivalent thermal power station in the boiler, so some people call it the “atomic boiler.” Nuclear power plant and other equipment and the same.

All nuclear power reactor should include nuclear fuel, moderator, and contains three parts hot agent.

1. Nuclear fission nuclear fuel to be able to place the material, such as uranium -235. Some reactors use natural uranium for nuclear fuel, reactors and some are content with a high enrichment of uranium -235 for nuclear fuel.

2, the role of moderator is to fission neutrons produced in high-speed slow down as quickly as possible, as easily lead to the thermal neutron fission of uranium -235. Commonly used moderator water, deuterium in the deuterium, heavy water is a very good moderator. In addition, the graphite is a good moderator. In fact, water and heavy water have also played the role of heat-carrying agent.

3. Rely on heat-carrying agent in the cycle of absorption heat released by Thinkpad T61 battery(14 inch) fission reaction, so that the temperature of the reactor will not be increased, and the heat transferred to the reactor to supply with. Heat carrier agent can be compressed gases, such as water or sodium vapor.

Many types of nuclear reactors, has to gas as the heat carrier agent, the gas-cooled graphite reactors as moderator; have to be filled with heavy water as moderator agent and to the natural uranium as fuel for heavy water reactor; have the ordinary water as heat carrier moderator agent and to low-enriched uranium as fuel for light water reactors -235. Light-water reactors are boiling water reactors and pressurized water reactors are two types. In both reactor types in on, he was up to the number of PWR.

The development of nuclear power, can be divided into three phases, is currently in the initial stage of fission can use, namely thermal neutron reactor nuclear power plant; the near future, will enter Liebian able to use the advanced stage, that stage of fast proliferation Dui ; the final stage will be the stage of fusion reactors fusion reactor, currently under study and explore the test, it is estimated in a few years after the application. Some scientists have again the three phases are called first generation, second generation and third generation.

Nuclear power has developed rapidly, from World War II, military needs to make the former Soviet Union, the United States, Britain, France and other countries, have developed their own atomic energy industry. These countries in the development of nuclear reactor and begun the study of small nuclear power reactor, to the 20th century 50’s, this research has made great progress. June 1954, the former Soviet Union built the world’s first 5,000 MW power generation plant, built in 1956, the United States a power output of 7.5 million kilowatts of nuclear power plants. In 1956, the world nuclear capacity based on an average 25.57. Rate of increase. Currently, there are 26 countries around the world and the region 428 nuclear power plants are running, nuclear generating capacity, of the total world electricity generation for more than 16%. The development of Thinkpad R500 battery nuclear power to become the trend of world energy development.

Nuclear energy use, energy development and utilization of human history, a huge leap forward. Energy experts commented that in the future diverse energy mix, nuclear power would be imperative to replace conventional energy sources, nuclear power status will gradually improve and become an important future direction for energy development.

Why the rapid development of nuclear power stations? Because it has many advantages. For example, it is an effective alternative energy, fuel, transportation is very small, power generation, low cost, security and environmental pollution and so on. It is precisely because there are so many advantages of nuclear power stations, so, whether industrialized countries and developing countries are actively developing nuclear power stations. Expected mid-21st century, nuclear power will become one of mankind’s main energy.

Radioactivity is found in 1896, to 1919, the first time, realized the artificial nuclear reactions. In 1939, the discovery of “chain reaction”, the people will it be possible to use artificial means to release the potential energy in the nucleus.

the second generation of plutonium fast breeder reactor fuel.

The second generation of reactors is a French design called the second generation of fast breeder reactors, since they gave it a nice name “Phoenix” reactor to plutonium as nuclear fuel, no moderator, and only liquid sodium as coolant (heat carrier agent). This type of breeder reactor has reached the commercialization stage. France has built an ultra-”Phoenix” type breeder reactor, used for power generation, power is 1.3 million kilowatts. France in the second-generation commercial fast breeder reactor, the leader in 10 years than any other country. Fast breeder reactors can produce even more than its own fuel consumption.

A fast fission of plutonium 239, the critical mass is small, some nuclear properties of uranium in a 235 than a good, important nuclear loading is nuclear power. But it’s toxic, high production costs, to build complex production reactor and reprocessing plant, to achieve industrial production. It is produced by slow neutron reactor bombardment of uranium -238 artificial production.

Made from natural uranium using the neutron component of uranium -235. Neutron fission of uranium -235 the amount of 2-3, these neutrons by the moderator will again cause fission of uranium -235. Maintain such a sub-neutron fission just enough rest to be slower than the outside of absorbed agents can make natural uranium into plutonium -239 -238 a. Therefore, the production of reactor fuel elements, both fuels, but also a raw material for production of plutonium -239. Plutonium from spent fuel elements in the -239 is separated. In fact, the production of the heap, which is to Toshiba Qosmio F55 battery burn part of the natural uranium in exchange for plutonium uranium -235 to -239, the average burn

An atom of uranium -235, -239 plutonium atoms are 0.8.

Made of natural uranium fuel elements, in the production of irradiated reactor fuel combustion and generate plutonium -239, but it should be sent to a dedicated separate reprocessing plant to separate the processing. We should not only not “burn” uranium to make separate recycling, but also the plutonium separated from other fission products.

After the treatment is divided into two kinds of wet and dry. Dry at a research stage of development, is mainly applied wet. Divided into wet precipitation, solvent extraction, ion exchange of three. Precipitation which is already obsolete, is mainly applied as solvent extraction, also known as the Purex process. Basic principle is to use uranium, plutonium and fission products of different valence in organic solvents have different separation factor, to them – separately.

After the separation of plutonium -239, but also purified to remove trace impurities, to a loading of nuclear energy.

Production reactor fuel by reprocessing, uranium and separated plutonium, uranium and -235 have a certain concentration, purification process, then by the conversion, to provide raw materials for the diffusion plant.

Lack wanted to use momentum from the waves? And absorbing device. I wave the sea containing uranium ions; take uranium product. : Knight, found a way to not only purify the water by uranium uranium into another, designing a species unique to the reactor charge, to eat the Dell vostro 1710 battery bottom of the reactor, however

Chapter VII of the colorful charm of nuclear power

Proliferation factor and critical mass in the general reactor, the production of plutonium few. But in fast breeder reactor, such as France’s “Phoenix” heap, but they can mass production of plutonium. This type of reactor production of new nuclear fuel than it consumes itself, but also much more, so called breeder reactor or the regeneration of the heap.

Why, “Phoenix” heap can be recycled reactor breeder reactor, or it? Because the “Phoenix” from the nuclear fuel is highly enriched with uranium and plutonium in the core -235, neutron throughput is 7.2X1015 / sec * cm 2. Other types of reactors

In order to maintain the fission reaction, need to slow down neutrons, and the “Phoenix” does not need to slow neutron reactors.

In order to fission neutrons on the nuclear bombardment of more effective, must be fast to slow. In each fission, the neutron to be fired out a rapid rate, can reach thousands of meters per second 2, which is called fast neutrons. To enhance the possibility of new fissile must reduce the speed of neutrons, which is to reduce its energy, has the speed down to 2 km per second, which is called thermal neutron neutron. Then easily be absorbed uranium nucleus, causing fission. Released about 2 per fission? 3 fast, if 1000 nuclear fission, can generate ideas about 2,500 neutrons, these neutrons to the direction of movement, and with the various elements of the nuclear reactor collision This movement is called the spread of neutrons. In the diffusion process slowed neutrons, and some neutron leakage to the reactor to go outside, some neutrons are absorbed by various non-fissile element, therefore, can become another new thermal neutrons and is the nucleus of uranium -235 absorption and fission occurred not more.

If in the process lost 1,500 neutrons, so able to maintain 1000 nuclear fission occurs, then the Dell studio 14 battery multiplication factor is equivalent to 1, just a self-sustaining chain reaction occurs, the reactor also constant power to continue to work down.

From the above description can also be seen, the so-called growth factors, is the second-generation nuclear fission, the number of first-generation fission of nuclei with the ratio of the number. The process of fast neutrons into thermal neutrons from the uranium nucleus after absorption of this type of reactor, known as the thermal neutron reactors. The “Phoenix” heap is caused directly by the next generation of fast neutron fission of uranium, so called fast neutron reactor.

The so-called critical mass, that can produce fuel chain reaction Xuyao the minimum amount of material, Dang below this amount of nuclear fuel, can not sustain chain reaction continues, Zhiyoudadao or Chaoguo the amount of chain reaction can continue. Using natural uranium as fuel in thermal power of 1650 MW reactor, the required 400 tons of natural uranium can produce 500 megawatts of electric power. However, in this heap, but also 2,500 tons of graphite, graphite is used to slow down neutrons, and therefore, using natural uranium as fuel in the reactor is a thermal neutron reactors.

If this heap to use the enriched uranium -235 3.35%. Uranium as fuel, this type of reactor fuel needed is 70 tons up to 2600 MW thermal power, electric power up to 890 MW.

The spectral efficiency of wireless communication systems, information capacity and transmission rate developments, the proposed antenna more Gao requirements. From the initial mobile devices for portable whip antenna, and now dual-band compact handset antenna, the antenna towards the multi-band wideband, small size, high efficiency, low cost, easy integration direction. With the development of wireless communications, especially after future 3G and Ad-Hoc networks, in order to better improve communication performance against multipath fading and interference with adjacent users in the user terminals on demand has become increasingly smart antenna the more urgent. Some simplified smart antenna that new research and development, such as parasitic antennas and reconfigurable antennas transfer. In order to meet the harsh environment and limited wireless bandwidth spectrum high capacity mobile communications, data rate Gao, Gao coverage, high spectral efficiency, high reliability requirements, in recent years, UWB / SP wireless communication HP 4510s battery technologies has caused a great deal in the international of fever, one difficulty is that the design of ultra-wideband antenna; In addition, more than at home and abroad are being vigorously developed input multiple-output (MIMO) technology is also possible that one of the important technical breakthrough.

Below 7 on the multi-band mobile broadband terminal antenna, reconfigurable antenna, ultra wideband / short-pulse antennas, multiple-input multiple-output mobile terminal antennas for a description of developments.

1. Multi-band mobile broadband antenna justice

To enable communication systems to applications in multiple frequency bands simultaneously, including multiple communication frequency bands, the same communication terminal on a variety of wireless services, such as GPS, Bluetooth, WLAN and other services, multi-frequency / broadband antenna is the key issue. In addition, for a variety of commercial, civil and military needs, mobile communication terminals of conformal antennas, small size, Gao efficiency, low cost, easy integration into a new hotspot. As the antenna bandwidth, size, efficiency, and constraints are interrelated, and therefore taken into account how the three to find the balance point to achieve the best effect, is the design of mobile terminal antenna research focus.

2. Reconfigurable antenna

In the future 4G and Ad-Hoc and other wireless communication systems, wireless access to further enhance the system capacity and performance, has a smart antenna can be used, such as parasitic power transfer antenna. Parasitic tune the antenna is usually only one RF channel, but around the parasitic elements through the electrical resistance changes in the value loaded antenna in the whole plane to within a scan, a low-cost, simple system and so on. Parasitic tune the antenna is a reconfigurable antenna. Reconfigurable antenna, including frequency of reconfiguration, reconfigurable pattern, polarization can be reconstructed and also Lenovo Y650 battery has several characteristics of the antenna can be reconstructed, and its research unit involved in antenna, antenna array and control algorithms. In recent years, international conferences and academic journals which, on the reconfigurable antenna rapid increase in the number of articles, has received considerable attention, and its effective analysis and design theory a lot of work to be done.

Reconfigurable antenna is an important issue is to select superior performance to the antenna switch and integrated them. With the recent high-performance, low power micro-electrical mechanical (MEMS) switches and a number of GaAs PHEMT switches such as the emergence of technology, making the development of reconfigurable antennas have a better future. Switch is the ideal switching characteristics, a high isolation, low power consumption, easy to integrate. Now widely used in mobile communication performance of GaAs switches have also been significantly improved. 3. Ultra-wideband / short-pulse antennas (UWB / SP>

In recent years, ultra-wideband / short-pulse wireless communication technology in the international arena has caused a tremendous research interests. It has the energy in the home, office space and within a short distance to provide high-speed transmission, and without taking up additional spectrum resources and a series of advantages, so as to form personal networks (PAM) 8 and to meet strong global demand for greater bandwidth provided ideal way.

UWB / SP system to deal with the short pulse time domain signal, its spectrum covers a very wide, in order to ensure that the signal received by the antenna radiation and the time domain waveform is not distorted, which called for Gao fidelity, it is not only required for the antenna in the frequency domain UWB, but also to ensure that the antenna phase center with the same characteristics of UWB.

4. Multiple Input Multiple Output (MIMO) antenna next generation mobile communication technology, wireless broadband communications technology, the research group aims to make wireless communications spectrum efficiency, capacity and speed have increased tenfold or even hundredfold. Multiple-input multiple-output (MIMO) technology is probably one of the important technical breakthrough. Systems used in transmitting and receiving end of multi-antenna signal to control the spatial distribution, at the same frequency at the same time under the conditions of use of multiple antennas to provide parallel subchannels to increase system capacity or through spatial Toshiba NB200 battery diversity to enhance the quality of signal transmission Gao.

(1) adaptive MIMO technology.

MIMO technology is an important trend is adaptive multi-antenna technology. Traditional MIMO system requires the same number with the number of antennas the higher the price of RF transceivers. The adaptive MIMO system may use the number of RF transceivers less than the number of antennas with reconfigurable antenna MIMO system based on environment / channel automatically selected conditions, adjust the antenna elements used to obtain a small space correlation channels and large channel capacity.

(2) broadband multi-antenna technology miniaturization.

Mobile communication terminal by the mobile terminal multi-antenna systems, especially mobile phone measures only one wavelength or even smaller very strict restrictions, and require smaller antennas and seek with the mobile terminal equipment conformal. If we want such a harsh place multiple antenna size constraints and its corresponding control circuit Yi support adaptive techniques are in the Tian Xian unit, the control circuit miniaturization Tichu extremely difficult requirements. At present mobile communication systems and mobile personal communications systems used by the standard antenna structure is a monopole antenna or the built-in PIFA, the antenna is clearly unable to meet both the need for multiple antenna systems.

Therefore, mobile terminals, particularly in mobile terminals, on one hand required size of the antenna element itself to further miniaturization and high efficiency; the other hand, work to solve the original wide-band single antenna element in the application to multiple antenna system, after some band antenna unit of work becomes narrower, so as to achieve scale mobile broadband multi-antenna systems. In addition, mutual coupling between antenna elements ProBook 4515s battery Yi in isolation is a key indicator of the efficiency impact of the antenna, the antenna matching unit to be good, mutual coupling / isolation determine the antenna efficiency, but also the correlation between antenna elements and antenna The pattern, which directly affects the capacity of MIMO communication systems and quality.

August 12, 1981, IBM started joint Microsoft and Intel co-production of civilian micro-computer. The so-called civilian is to give individuals and general business use, this can be a truly personal computer. It’s CPU is only clocked at 4.77MHz memory 64K. The operating system is Microsoft produced DOS1.0, the price of this computer up to 3 005 U.S. dollars. Apple Computer was advertised to the 18 on into the personal computer market welcomed. 18 on the 5150 called the Personal Computer?, It means in English inside the PC, then out of it, the first letter of the two words together, called a PC.

IBM PC’s birth, to the computer industry has brought far-reaching impact. IBM PC, Lenovo Ideapad Y650 battery the significance of the most revolutionary is that it is open standards, IBM open all the technical details and design secrets, where it bought the operating system from Microsoft, and from there to buy the Intel CPU chip, and allow Microsoft and Intel You can sell other companies products again. IBM is willing to disclose all technical documents, sincerely welcome the development of peer-to join the ranks of the PC. For IBM, this step lightly, this giant of the world’s most traditional groups, public renunciation of all hardware and software alone manufacturing strategy, not only the general user Renke the personal computer, and to promote electronic and computer companies around the world competing Transferring PC, copy out the product is IBM PC compatible.

IBM PC appearance, led the personal computer market, a huge development, as the world’s personal computer market has great potential, it has always maintained a fast momentum; also the associated computer-related and other industries, such as software, electronics, materials , network, etc., are driven by its rapid HP ProBook 4311s battery development has made to the world brought great economic benefits.

Apart from the economic and social benefits outside the PC, also known as personal computers, PC on us personally, influence is enormous. Because of its powerful, it changed the way we work, study and live. Now, a person can stay at home work at home, learning, living, as long as there are networked computers at home can be.

Apple’s philosophy is Think Different (extraordinary;). Apple has always insisted on their own ideas, whether software or hardware are doing different, kind of cold the computer image removed from people’s minds, creating a colorful and user-friendly computer age.

In addition to personalized look outside Apple’s performance is very outstanding, TOSHIBA Satellite E105 battery especially in graphics processing. As Apple’s powerful graphics capabilities, often used as a graphics workstation for graphic, video and design work, therefore, its price is also more expensive than the PC computer.

Compared to other companies like Apple with a technology innovator and artist, rather than commercial home disadvantage in the market competition is inevitable, a company against the entire PC industry, and the natural is not a victory. But in recent years, Apple has made great progress, it is the market and the needs of users on the first one, the recent diversification of the business philosophy initial success, iPod and other Apple products, hot drive performance, but that does not Apple represents all accepted by the market, compared to other IT giants, Apple is still not really strong.

The reason why the decline of Apple, is its pride and strength. Apple is not compatible with too many things, from hardware to software, seem to earn their own living one person to control the entire market, while Microsoft and the PC open to ideas to conquer the whole world, the apple is still no such sense of openness, Apple, if not to market to do the greatest degree of compromise, then Apple will never become a mainstream choice, always played in specific VGP-BPS15 battery areas of expertise in the role of the nobility alone.

20th century 90’s, Apple’s Steve Jobs back at the former president, since then, Apple’s image of the fashion alternative to re-cut a striking figure in the II sector, which causes great concern to computer users, Apple’s old and therefore advocate cheered.

January 2006, Apple announced the Macintosh with Intel processors to produce series of personal computers, Apple Computer turning Intel. Apple Computer Inc. said it will end in 2007, have adopted all of its flagship product of the old processor. This shows that Apple started to give up its policy of not opening up the future how, let us wait and see.

Battery storage life refer to standard rules Ding or human cells under the conditions of charge storage time, in general, until after the end of the battery storage, battery capacity requirements remain some value, otherwise, as does not meet the storage life requirements, or as a storage life is short, the main factors affecting the storage life of the battery occurred within the physical, chemical, electrochemical changes.

A battery is the battery life under certain discharge continuous or intermittent discharge, discharge to the termination voltage of the time, the main factors affect the life of the system is discharging the battery’s capacity, active material utilization, resistance, etc.

The cycle life of secondary battery is charging and discharging of a certain system, ProBook 4710s battery capacity reduced to the specified value before experienced the number of charging and discharging, or cycles, cycles. Affect the cycle life of secondary battery main factors: the battery inside the impurities, batteries and electrode structure, the nature of the electrolyte, the stability of active substances. The main impact of different factors of the battery not the same.
