摘　　要：利用有色对称理论解释了各种晶体结构的空间群转变的规律性问题。得出：一个有色空间群（子群）可能代表一个相转变，从单色空间群（母群）转变为有色空间群（干群）意味着结构或是从无序变体向有序变体转变；或是从母体结构向衍生体结构转变；……等。亦即各衍生体的空间群必定是母体空间群的有色空间群（或子群）。We take the advantage of the theory of coloured symmetry to discuss the variation of allkinds of space group when the crystal mutates, and their regularities. A coloured space group mayrepresent one sort of variation. Form single colour to coloured space group, it means the structurevaries from disorder to order, from its mother structure to derivative, and so on. Finally, the the-ory of coloured symmetry is used to il1ustrate the regularities of space group variation in crystalstructure.
