摘　　要：文中论述了随机变量的筛分与混和现象；由Ｋｏｌｍｏｇｏｒｏｖ－Ｓｍｉｒｎｏｖ检验表明，筛分与混和对随机变量分布的影响是强烈的；基于顺序统计量理论和Ｌｅｂｅｓｑｕｅ分解定理，导出了筛分律与混和律的表达式。Screening and mixing is a general phenomenon in statistical analysis of strength of fibres and its composites. In this paper, the fundamental concepts and terms of screening and mixing phenomenon have been expounded first. It has been showed that the effects of screening and mixing on distribution is strong by the Kolmogorov Smirnov's test. The expressions of the screening law and the mixing law have heen derived in view of the order statistic theory and the Lebesgue's decompose theorem, and the correctnes...
