Li Shenghong1,Zhou Zhangong2(1.School of Mathematics and Physics,Jiangsu University of Science and Technology,Zhenjiang Jiangsu,212003)(2.School of Information and Engineering.,Jiaxing University,Jiaxing Zhejiang 314001,China)  
For a general multiple Gauss-Markov model E(Y)=XB,cov(Y)=σ2∑V,∑ and V are the positive definitive matrices,and SB is an estimable function.The paper gave the definition of the linear Minimax estimator.Moreover,it obtained respectively the unique linear minimax estimator of the estimable function SB in linear estimator with two specified matrix loss functions.
