New Study in Simplified Formula of Variance Components Estimate

WANG Zhong-feng(Changchun Institute of technology,Changchun130012,China)  
This paper advances a new simplified fomula of variance components estimate,that is the one to distribute the redundant observation components to every measured value,discusses its statistical property,and proves that it is practical by a example.
