用微观半经典Ｖｌａｓｏｖ方法研究了同位旋矢量巨偶极共振（ＧＤＲ）的系统 学．计算的ＧＤＲ强度分布的峰位能量和宽度与实验结果是一致的，并与经验公 式相符．计算还表明峰位能量有微小的同位旋效应，而峰的宽度几乎没有同位 旋效应．
The microscopic semi-classical Vlasov method was used to study the systematics of isospin-vector giant dipole resonance (GDR). The peak energy and width of the calculated GDR intensity distribution are consistent with the experimental results and agree with the empirical formula. The calculations also show that there is a slight isospin effect at the peak energy, while there is almost no isospin effect for the width of the peak.
