the first generation of computers,which used vacuum tubes,came out in the late 1940s.univac I is an example of these computers which could perform thousands of calculations per second.in 1960,the second generation of computers was develop and these could perform work ten times faster than their predecessor.the reason for this extra speed was the use of transistors instead of vacuum tubes the second-generation computers were smaller,faster and more dependable than first-generation computers.the third-generation computers appeared on the market in 1965.these computers could do a million calculations a second,which is 1000 times as many as first-generation computers.unlike second-generation computers,these are controlled by tiny integrated
circuits and are consequently smaller and more dependable.fourth-generation computers have now
arrived,and the integrated circuits that are being developed have been greatly reduced in size.
this is due to microminiaturization,which means that the circuits are much smaller than before；as
many as 1000 tiny circuits now fit onto a single chip.a chip is a square or tectangular piece of silicon,usually from 1/10 to 1/4 inch,upon which serveral layers of an integrated circuit are etched or imprinted,after which the circuit is encapsulated in plastic,ceramic or metal.fourth-generation computers are 50 times faster than third-generation computers and can complete approximately 1000000 instructions per second.

英语翻译
By the late 50s though,as vacuum tubes were being replaced by bipolar junction transistors (BJT),tubes survived only in niche applications,such as wideband distributed amplifiers,as the BJT is basically a low to medium impedance device,and as such,is not very compatible with distributed amplifier theory.

英语翻译
The new design incorporates a large oil-less vacuum pump and a high power engine,allowing faster water suction and discharge,making it superior to any other competing brand in the same class.
Separate oil filling system eliminates the need for fuel mixing.If the lubrication oil become empty the a warning indicator will alert the operator and the engine will automaticlly shut dowm
