摘　　要：对两因子的两次重复试验随机模型,在误差方差具备齐性的前提下,推导了随机效应存在性的检验规则.在两种情况下分别导出了模型的均值差的置信区间.讨论了置信区间的平均长度的变化规律.On the basis of the homogeneity of error variance,according to the random model in double repeated experiment with two factors,a test rule for the existence of random factors was deduced.The interval estimation for the difference of mean values was also presented.The changing pattern of mean length of the confidence interval was revealed.

关 键 词：随机模型 均值差 置信区间 假设检验
