营养试验中消除动物异质性的研究

STUDY ON ELIMINATING HETEROGENEITYAMONG ANIMALS IN NUTRITIONALEXPERIMENTATION

本文提出利用随机不完全区组设计消除营养试验中动物异质性的方法，并举出实例说明方法的应用。计算结果表明，这种方法能有效地校正处理、误差平方和与处理均数，相对于完全随机设计能增加设计效率６３％，对提高试验结果的可靠性具有重要作用。

? The author of this paper proposed the method of eliminating the heterogeneity among animals in nutritional experimentation using randomized incomplete block design,and gave a practical example in illustration of this method for useThe computational results showed that treatment and error sums of square and treatment means are adjusted,and that the desigh relative to complete randomized design has a gain in efficiency of 63 per cent for playing an important role in improvement in the reliability of observational data〖KH*2]
