摘要

本文利用有色对称的理论讨论了螺旋型高分子链晶体结构所属空间群的演变规律性。得出：(1)有序链结构的空间群是无序链结构空间群的有色空间群；(2)对称性较低的螺旋链所属空间群是高对称螺旋链所属空间群的有色空间群；(3)从而得出空间群演变的方向、途径和结果，总结出其演变的规律性。

Abstract

The present paper investigated the varied regularities of space group of crystal structure of helix type polymer chains in terms of coloured symmetry theory. The results indicate: (1) For the same polymer

the ordered arrangement of chains must have a space group that is the coloured space group of the discordered arrangement. (2) For the different helix-type polymers

the lower symmetry crystal form must have a space group that is the coloured space group of the higher symmetry form. (3) The direction

path and result of a change from the space group to its coloured space group are given.
