摘要
系统阐述了实用完备模态空间（ＰＣＭＳ），对该ＰＣＭＳ与原完备模态空间的等价性给出新的证明；又借助一种优化正交技术对ＰＣＭＳ作了改进，这种改进对某些应用是必要的。ＰＣＭＳ已成功应用于多个方面。同时，将本文结果向复模态空间进行拓展也是很有意义的。
As summary of the study of Practical Complete Modal Space(PCMS),this paper describes systematically the authors results scattered in literatures.For the requirement of applications,a new PCMS improved by using an optimal Gram Schmidt orthogonalization method is proposed.The accomplished applications of PCMS in some respects are briefly presented.Of course,the PCMS described in this paper is not the best.
