By using AM1 method, the structures and electronic properties of N-methyl-2.(2.-thiophene)-pyrrolo[3,4]C60 (MTPC) and N-methyl-pyrrolo[3,4]C60 (MPC) have been studied. Based on the AM1 geometry optimizing, the electronic spectra and second-order nonlinear optical polarizabilities (() of MTPC and MPC were calculated by using INDO/SCI method combined with Sum-Over-States (SOS) expression.

努尔哈赤和皇太极的天命思想具有明显不同,前者的核心是“皇天眷佑后金”,而后者的主流意识是“天命靡常,惟德是辅”。他们的天命思想经历了一个从“敬天”到“信天”再到“疑天”的演变过程,最终完成了与儒家天道观的接轨。他们天命思想的每一次演变都与后金政治的内容和运作方式密切相关,而历次演变了的天命思想都或推进或制约了后金及大清社会的发展。
