在农业科研中,常遇到一些同处于一个统一体中的随机变量,这些变量互相联系,相互制约。为对各变量的数量关系进行定量化分析,需要用大量的原始数据,经过繁琐的计算。这样不但费时,而且易于出错(特别在变量较多时)。用计算机承担这个任务可以顺利地解决这个矛盾。 In agricultural research, we often encounter some random variables in the same unity, which are interrelated and mutually restricted. In order to quantify the quantitative relationship between variables, we need to use a large amount of raw data, after tedious calculations. This is not only time-consuming but also prone to error (especially when there are many variables). Using computers to undertake this task can smoothly solve this contradiction.
