In the case of 〓unknown,this dissertation derived the exact distribution of related statistics,and thenproposed the multivariate covariance control charts:the A chart and the 〓 chart based onthe sample generalized variance and the maximum and the minimum eigenvalues.

当分布参数〓未知时，本文通过推导有关统计量的精确分布，建立了基于样本广义方差和最大、最小特征根的多元协方差控制图—A图和〓图，为实际应用奠定了基础。
