理论和实验上证明了电偶极矩Ｄ同角动量Ｉ近似满足线性关系，说明了Ｃｏｒｉｏｌｉｓ力和离心为对Ｄ的作用．第一次借权重线性最小二乘法拟合得到３１个核实验的基态电偶极矩Ｄ０．比较了宏观－微观方法，平均场理论，分子偶极集团模型和实验的Ｄ０。 The theoretical and experimental results show that the electric dipole moment D and the angular momentum I satisfy the linear relationship approximately, indicating the Coriolis force and the centrifugal effect on D. For the first time, the ground-state dipole moment D0 of 31 nuclear experiments was fitted by linear least squares method. The macro-microscopic methods, mean field theory, molecular dipole group model and experimental D0 are compared.
