摘　　要：对于由不同总体中取出的个体所组成的混杂样本在某一试验因素作用下的统计检验问题,本文提出了一种归一化的处理方法。即通过一组可将各总体化为同一预定分布的变换,滤去混杂样本中各元素从其原总体继承的由环境因素所致的分布特异性,使之成为简单随机样本,从而使我们可以排除环境因素的干扰,单纯地分析试验因素的效应。This paper deals with the problem of statistical test of a mixed sample which consists of individuals from several different kinds of population. By means of a group of transformations which can convert each population to the same distribution, we reduce the mixed sample to a simple random one. Thus we can eliminate the effect of environmental factors from the mixed sample and merely analyze the effect of the experimental factors.
