本文以H_2和Na_2的静电计算为例,对静电方法进行了分析,指出静电平衡准则在静电计算中的重要作用。无疑在静电计算中波函数的选择是起决定作用的。本文的计算和分析进一步指出,波函数中波函数的类型是起决定作用的,而轨道指数的不同选择方案影响是次要的,这就为进一步改进静电方法指明了方向。 In this paper, we take the electrostatic calculation of H_2 and Na_2 as an example to analyze the electrostatic method and point out the important role of electrostatic balance in electrostatic calculation. No doubt in the electrostatic calculation of the choice of wave function is decisive role. The calculation and analysis in this paper further point out that the type of wave function in the wave function plays a decisive role, while the influence of different choice of orbit index is secondary, which indicates the direction for further improvement of the electrostatic method.
