散分了``请大师现场翻译一下``有关计算机的！

请翻译下段文字！（如是机器翻译那就算了`）
人们有时候用“代”来为现在计算机分类，每一代都以某种重要技术为特征。第一代计算机使用真空电子管作为逻辑门。著名的第二代计算机中包括UNIVAC 1，建成于1951年。第二代计算机于1962年前后开始出现。当时CDC和IBM公司成功的推出第一台采用晶体管的商业性的计算机。60年代后期到70年代，集成电路的使用标志着第三代计算机的诞生。它使以较低成本建造速度更高、性能更可靠的计算机成为可能。到了80年代，计算机开始采用大规模集成电路个超大规模集成电路，它们通常被称为第四代计算机，尽管它们与第三代计算机相比，差别并不十分明显。第五代计算机突出了人工智能，着重研究机器推理及逻辑编程语言等。它与前几代计算机不同，因为，到目前为止，其研究成果尚未对商业性的计算机市场产生任何直接的重大影响。
参考答案:Sometimes people divide computers by "generation",and each generation take some important techniques as a characteristic.Vacuum tube is used for logic door in the first generation.The second generation included UNIVAC which setted up in 1951,appeared about 1962.The CDC and IBM company released the first transistor computer successfully .Between late 60's and 70's , the usage of the integrated circuit symbolized birth of the third generation .It maked lower in cost, higher in speed and more dependable in function computer possible.Till 80's, the computer made of large scale integration and super large scale integration. They usually called the fourth generation, though there were little difference between the thirth generation and the fourth .The fifth generation's advantage is artificial intelligence, and that's differents arelogical machine and assemble language .
So far, its research hasn't brought any direct important influence on business computer market.
