摘    要:利用分子对称性对矩阵进行分类。通过引入对称-矩阵和超矩阵概念,并确定它们的运算规则,从而极大地简化了计算,节省了内存和改善了收敛性。由于采用了分壳层计算,避免了大量重复计算。在程序的编制中还利用了数组动态存储技术,使程序能同时用于微机和其它类型的计算机。

关 键 词:分子对称性  矩阵  从头计算程序

Abstract:The matrix elements can be grouped into shells by means of the molecular symmetry. By introducing the concepts of symmetry-matrix and symmetry-supermatrix and determining their operation methods, the computational efforts and computer memony can be greatly reduced. By using the shell integral technique, a lot of repeated calculations can be avoided. The method of storage dynamical allocation is also used in programming, so the program can run on microcomputer or other kinds of computers.
Keywords:molecular symmetry   matrix   ab initio calculation program
