在发展一揽子分子轨道法和多环芳烃线性符号、即特征数的基础上，提出了适用于任意共轭系的，蕴含分子一切拓扑信息的线性符号；即包括无环系、稠合系、集合系、非苯稠合系及其相应含杂原子系，取代衍生物系的特征数线性符号系统．提出了从这种简捷的线性符号，在计算机自动构成Ｈｃｋｅｌ矩阵和Ｆｏｃｋ矩阵的策略和方法．从而实现了无需输入矩阵，在算机上，原则上可对任意共轭系自动进行任意自洽场分子轨道计算的算法．
On the basis of developing a package of molecular orbitals and polycyclic aromatic hydrocarbons (PAHs) linear symbols, ie, the number of features, linear symbols suitable for any conjugate system containing all topological information of molecules are proposed. That is, they include acyclic systems, condensed systems, Department of non-benzene fused systems and their corresponding heteroatoms, substituted derivatives of the number of linear system of symbols. From these simple linear symbols, the strategies and methods of automatically constructing Hckel matrix and Fock matrix in computer are proposed. In this way, an algorithm that can automatically perform any self-consistent field orbit calculation on any conjugate system can be realized on the computer without inputting the matrix.
