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。
