摘　　要：本文研究了两水平无重复因析试验散度效应BH估计的性质,给出了BH估计无偏性的充分必要条件,求得了它的近似方差.并在多个模型下对BH与MH估计进行了模拟比较.In this paper,the property of BH estimator in unreplicated two-level factorial experiments was studied.The necessary and sufficient condition of the unbiasedness property was given.The variance of BH estimator was presented.Finally,the comparison of BH and MH estimators was taken through simulation.
