By applying these two tools,we mainly discuss the problems as follows:1 Perturbation identities for the generalized polar decomposition:By applying singular value decomposition, we study the perturbation bounds of the generalized polar decomposition under unitary invariant norms when A is perturbed by addition or multiplication,respectively and give our bounds in identities.2 A class of new unitary invariant metrics: This paper generalized a class of new unitarily invariant metrics and give the upper-bounds and lower-bounds by C-S decomposition.

利用这两个强有力的工具，本文主要讨论了如下问题：1 矩阵广义极分解的扰动等式：利用奇异值分解，本文分别讨论了加法扰动和乘法扰动下矩阵广义极分解在任意酉不变范数下的扰动界，并首次以恒等式的形式给出了酉极因子和半正定因子的扰动界。2 一类新的酉不变度量：本文推广了文[22] 中的结论，定义了一类新的酉不变度量。

When treat-ing the spectra, transition, scattering problems, we must use the semi-microscopicapproach. The main new conclusions in this thesis are following:We found the different shrinking effect in ∧ hypernuclei and 〓 hypernuclei, the shrink-ing effect in ∧ hypernuclei are confirmed in a recent experiment;We also found a new approach to treat the configuration mixing of ∧∧ hypernuclei and〓 hypernuclei and that the conversion process may change the spectra and widths of〓 hypernuclei;For the first time, we investigate the neutron star matter without the ∑ hyperon butwith the new meson 〓(975) and φ(1020), we found the contribution of 〓 and φ canmake the equation of state of neutron star soften, and the maximum mass of neutronstar reduces;we extract a set of optimum parameters of the optical potential for the scattering of 〓with nucleus, we found that the 〓 nucleus optical potential need a bigger imaginarypart.

本论文所取得的主要新成果是：独立揭示∧超核和〓超核的不同的收缩效应，其中∧超核的收缩效应被最新实验证实；提出了处理∧∧超核与〓超核混合态的新方法，并发现conversion过程使〓超核能谱和宽度改变；首次在中子星研究中在不包含∑超子的同时考虑新介子〓(975)和φ(1020)，并发现这可使中子星物质的状态方程变软、中子星半径变大、质量变小；独立提取了〓核光学势的一组最佳参数，并证明〓+核光学势要求一个较大的虚部。
