摘要
本文简短地评述了模型修正中现有若干完备模态空间技术,并强调了在模型修正中利用完备空间作为参考基的重要性。同时证实了完备空间内的两种矩阵型公式的相通性。随后,本文又引伸出完备空间内的两种元素型模式,其中之一正是作者曾提出过的。最后略述了完备模态空间内的设计参数修正法,并同时又推荐了一种可供使用的完备空间设计参数法。
The some complete space teehniques in the field of model correction are briefly revi- ewed and the signification of using Complete Modal Space(CMS)is emphasized in the present paper.Also the identicalness of two matrix-type methods in CMS is demons- trated,which means such two kinds of the formulae are essentially the same.Then the paper has derived two element-type formulae and has suggested one procedure of design parameter correction in CMS.
