- 对于Epstein-Nesbet划分,微扰展开式是大小一致的. 而对于另一种划分(Chen,F;Davidson,E.R.;Iwata,S.Int.J.Quantum Chem.,2002,86:256,见公式(24)的讨论),其展开式大小不一致.One perturbation series corresponding to the so-called Epstein-Nesbet partition was found to be size consistent up to the fourth order,and another perturbation series(Chen,F.;Davidson,E.R.;Iwata,S.Int.J.Quantum Chem.,2002,86:256,see the discussions about Eq.(24) ) was found to be not size consistent starting from the second order.
