自从1946年世界上第一台电脑诞生以来,电脑技术日新月异,令人类的生活图象大为改观,世界因它的存在正以空前的速度向前发展。作为水利人,电脑也愈来愈向我们走近。但许多人还是不能全部明白:电脑到底能为自己作些什么? 1.运算工具。这是人类开发计算机的最初动机。如π值的计算,18世纪的数学家高克斯花了20年方算到707位,而现代计算机推算到上千万位也仅几小时的功夫。今天,计算机在高科技研究及工程设计等领域的计算能力,使人们的工作效率空前提高。如果你是一位技术人员,完全可以充分利用 Ever since the birth of the world’s first computer in 1946, computer technology has changed so rapidly that the images of human life have greatly changed. The world is at an unprecedented rate because of its existence. As water conservancy people, the computer is approaching us more and more. But many people still can not fully understand: what can computers do for themselves? 1. Computing tools. This is the first human motivation for developing a computer. For example, in the calculation of π, the 18th century mathematician Max spent 70 years in 20 years, and modern computers count to tens of millions of hours and hours. Today, the computational power of computers in the fields of high-tech research and engineering design enables people to work more efficiently. If you are a technician, can take full advantage of
