The Other is to get the value through the stationary value principle of general potential energy or other similitude method with correlationenergy.
另一类是用总势能驻值原理或其他类似的有关能量的方法求解。

In this paper we discussed the method of selection of pair correlation functions and the rectification of interelectronic correlationenergy in molecular systems.
本文讨论了分子体系中对相关函数的选择以及电子相关能的校正问题。

Meanwhile, the correlationenergy calculated by the hybrid approach of DFT and HF is smaller than the HF value in magnitude, the difference being explained by the stationary correlationenergy.
