Atomic reactors use a lot. From the energy point of view, atomic reactors for submarines, icebreakers and other large ships and provide the impetus, but also can be used to generate electricity and heat. Is called nuclear power plant for power generation; for heating is called nuclear heating; both power generation, it is called the nuclear thermal power station heat.

With atomic-powered power plants, known as the nuclear power plant. Atomic power generation and general thermal difference not only fuel, (more…)

At present, solar stills and more used in the desalination area. We know the total amount of water on Earth although many have 1.5X1018 cubic meters, of which 97.3% is brackish water, fresh water in the remaining 27%, 2% of ice, snow and ice distribution in the polar zone and other iceberg, only 0.7% of fresh water located in rivers, lakes, for people drinking and irrigation purposes, it is not enough. In addition, with the (more…)

When we plug the memory what needs attention?

Some may think that there is nothing special about installing memory, but a lot of memory failures are due to irrational swappable memory due to the current mainstream DDR SDRAM, for example, when the first installation of the memory slots on both sides of the card Bankai Button, then observe the slot, you can find the middle of a protruding slot position. The pins on the memory also has a gap. Hold the memory ends, to align (more…)

In the course of computer failure is inevitable, I do. Typically, these failures are the more simple failure to understand the phenomenon through the fault. User can easily troubleshoot. Will also introduce the most common computer maintenance and routine maintenance methods, computer out to minimize the risk of failure.

When a computer failure, a first step into chaos square inch, the analysis on the fault occurred, such as memories of what was performed before failure occurs Naxie operation; produce what is more the fault phenomena; then the phenomenon of these failures to determine the causes of (more…)

As wireless communications, wireless networks worldwide and the rapid application of a wide range of fields, with high technology and military and civilian needs, has been the rapid development of microwave technology. Microwave industry and supporting the rapid development of academic activities is also very active, electromagnetic theory and microwave technology are also new challenges in further development.

(A) Subject Development (more…)

CPU integrated 10 million or even billions of transistors, can be divided into the control unit, logic unit, memory unit of three parts. Internal structure can be divided into: integer arithmetic units, floating point unit, MMX unit, L1 Cache unit and register.

Performance design mainly refers to the design of the electrical properties of the battery. Is designed to solve the key problems in the past, experimental data have been accumulated and accumulated experience in production, based on the performance of batteries designed to carry. Include operating voltage, operating current, capacity, life and other aspects of the design. (more…)

The concept of the battery safety of lives and property from damage and are closely related. Safety is no unacceptable risk of injury. Safety is to avoid the risk of injury and performance requirements to meet the other requirements of a balance between the security is relative, not absolute safety, even the highest security products, it will be relatively safe, so the risk assessment and security on the (more…)

China started in 1958, solar cells, developed in 1959, the first one with practical solar cell, first used in 1971, China successfully launched the second satellite, terrestrial applications in 1973. Semiconductor industry in 1979 began production of the defective silicon single crystal silicon solar cells, solar cell costs decreased to open the market for ground applications. In the 1973 to (more…)

Practical fuel cells are generating the biggest obstacle to cost. Cost of power generation equipment at the time mainly by the development costs (mainly stack of material and manufacturing costs) and run-time fuel consumption, maintenance costs, battery-for-use fees, operating costs (long-term costs) to decide. Make the (more…)
