另外，通过与膨胀蒸发源模型及同位旋相关的渗透模型分析结果的比较，发现这种差别主要是由同位旋相关的反应动力学所造成的。

Several isospin amplitudes are found to be larger than the one from BSW factorization method.

这表明B介子无璨弱衰变存在较大的末态相互作用。

Since ρ〓,ω are neutral vector mesons, the G-parity breaking is caused by the isospin symmetry breaking. We study the form factor of π, F〓, which is an important observable related to ρ〓-ω mixing problem.

在这个问题中，由于ρ〓，ω都是中性矢量介子，因此G宇称的破坏主要是由同位旋对称性破缺引起，在讨论这个问题时我们首先讨论了对ρ〓-ω问题有重要意义的π介子的电磁形状因子F〓。

The development of new experiments for neutron halo is briefly described, while the isospin and energy dependence of Glauber theory and its importance in describing halo nuclei -nucleus scattering are discussed.

The effective interactions extracted in the RMF approximation contain the effect ofthe DBHF short range correlation and isospin structure.

提取的在RMF下的有效相互作用包含着DBHF的短程关联效应和同位旋结构，为研究有效相互作用的同位旋相关性提供了理论基础。

We compare the results with the analytic results from the weak coupling limit and the strong coupling limit. As an extension, when think about the dispersion relations for SU(2) trapped bosons, we find that we can not get the inverse effective mass directly from the dispersion relations of the holon-isospin excitation for the wave function from Bethe equation is not the eigenstate wave function of the total momentum.

作为推广，我们还研究了无限深势阱中SU(2)玻色子的各类激发态的色散关系，发现由于直接的Bethe Ansatz 波函数不是总动量的本征态，所以不同通过直接的色散关系来给出质量有效质量比。

By calculating the neutron skin thickness of nuclei in the range of Z = 8 ~ 120, A = 5Z/3 ~ 3Z ,we find a linear relation between the neutron skin thickness and the isospin asymmetry degree δ:, which is in agreement with the result extracted from the measurements by antiproton annihilation method i.e.:.

我们发现中子皮厚度随对称能系数 a s 以及对称能在饱和密度附近的斜率L、曲率Ksym的增大呈现近似的线性增大的趋势，对称能越硬的核势确定的中子皮越厚。

We include the electromagnetic effects consistently in the QCD sum rule approach to keep the final sum rule gauge invariant. Then we study the role of electromagnetic effects in the isospin symmetry breakings of the system.

我们把电磁相互作用自洽地包括进来使最后的求和规则是规范不变的，然后研究电磁效应在体系的同位旋对称性破缺中的作用。

We make a concise review of this method and use it to calculate the radiative decays of the vector mesons, the baryon magnetic moments, the isospin symmetry breakings in π,ρsystem and πNN coupling constants. All of our results agree well with data.

我们对这一方法作了扼要的评述，应用它计算和分析了矢量介子的辐射衰变宽度，重子磁矩，π和ρ体系的同位旋对称性破缺以及πNN 耦合常数的同位旋对称性破缺等，都得到了与实验符合得很好的结果。
