Super capacitors have a wide range of uses. It is composed of hybrid and battery systems can be used to meet the car is accelerating, start climbing the high power requirements when, in order to protect the battery system and the emergency brake in the car is an instant energy recovery to reduce energy waste and save energy. Super capacitors are also used in other systems, such as the driving force for starting the fuel cell for mobile communications and computer backup power supplies. according to energy storage mechanism, supercapacitors can be divided into double-layer capacitors and capacitor Faraday quasi two categories. Double-layer capacitor is built on the basis of double-layer theory. Charging, the electrolyte dissociation occurs, the positive and negative ions toward the movement and were adsorbed on the electrode surface, formi...

We successfully 243 IC design companies in China conducted a full sample survey, the return rate as high as 41%! This reflects the new design industry hopes a strong desire to communicate with the buyer. Survey results revealed the questions focused on IC design companies to invest, lack of system knowledge, silicon integrated circuits is difficult and the buyers of the domestic aspects of cognitive problems. In fact, these are common difficulties encountered by new industries, require the system to plan, find a breakthrough. Let us first look at the overall IC market conditions in China. Chinas IC demand in 2001 the total number reached 24.3 billion, worth 128.7 billion yuan (98% of the value point of view needs to be imported.) Compared to 2000, the number of total demand growth of 4%, but the value increase of up to 31%; should be note...
