英语翻译
The invention of electronic computers makes it possible to free man from the labour of complicated measurement and computation.
A high speed electronic computer can carry out up to one hundred million arithmetical operations in one second.A computation which would have taken years of human work in the past is now done in a few seconds.A number of various complicated problems which could not be solved before have been solved with the help of computers.
Accurate measurement and exact computation are the bases of modern engineering and scientific research.Every engineering worker must determine accurately the amount of any change that the material to be used undergoes in different conditions.
And every science worker will have to make numerous accurate computations before he can say that the results of his experiment are correct.Yet there exist complex computations in science and engineering which science workers are unable to make because they are too long and too complicate.Here is an example which can illustrate how much time some of them may take.In order to solve a complicated chemical problem a chemistry worker must make about four million operations.It would take him years to work the problem out,while electronic computing machine would do the same job only in a few second.
We may divide electronic computers into two groups:machines that can control and those that can count.The former is used in satellites,guided missiles,weather-forecasting instruments and other devices,both simple and sophisticated.And the later can add,subtract,multiply and divide.Such machines are to do any operation which we can reduce to arithmetic.Besides,they are able to combine many problems and take them in any order.

电子计算机的发明使我们能够从复杂的测量和计算劳动力中解放.
一个高速电子计算机在一秒钟可以进行高达一亿算术运算.计算机工作在过去计算是要花费几年但现在只需要几秒钟.对以前许多各种复杂问题得不到解决的,现在在计算机的帮助下已经解决了.
准确的测量和精确计算,是现代工程和科研基础.每个工程的工人必须准确判断的任何材料可以在不同条件下经历的变化.
另外,每一个科学工作者将不得不进行大量精确的计算,才可以说他的实验结果是否正确.然而,存在着复杂的科学和工程计算的科学工作者都无法进行,因为他们太漫长,太复杂.这里有一个例子可以说明他们为此总共要花费多少时间.为了解决复杂化学问题,化学工作者必须作出约四百万次的操作.这将花费他多年去解决这个问题,而电子计算机器只会在几秒钟做同样的工作.
我们可以分为两类电子计算机：机器,它可以控制和那些可以计算的.前者是用在卫星,导弹,天气预测工具和其他设备,既简单又复杂.以及后来的可以加,减,乘,除.这种机器是做任何操作,我们可以减少算术.此外,他们能够将许多问题根据他们的重要性重新排序.
