The top eigenpairs at the title mean the maximal,the submaximal,or a few of the subsequent eigenpairs of an Hermitizable matrix.Restricting on top ones is to handle with the matrices having large scale,for which only little is known up to now.This is different from some mature algorithms,that are clearly limited only to medium-sized matrix for calculating full spectrum.It is hoped that a combination of this paper with the earlier works,to be seen soon,may provide some effective algorithms for computing the spectrum in practice,especially for matrix mechanics.

【摘 要】多年来，一直提倡的素质教育让我们反思一个问题：谁是课堂的主体？或者说谁是课堂的灵魂？是教师主体，还是学生主体，这要视教学内容而定，没有一成不变的固定模式，也没有一个明确的框架。本文通过一堂英语语法课教学详细阐述了自己的观点，希望与各位同行分享、共勉。 【关键词】素质教育 新课标 教师主体 学生主体 中图分类号：G4 文献标识码：A DOI：10.3969/j.issn.16
