| 摘 要： | Schoenflies记号和国际记号描写对称性时,常常由于一号多义导致混乱,本文提出了克服这种混乱的建议,确立了对称元素Sn与、点群与Sn的关系。依据群论的观点将32个晶体点群划分为7个晶系,每个晶系以最大子群为代表并包括所属的其他子群。

| Abstract: | In describing the symmetry of molecules and crystals with the Schoenflies notation and international notation, these notations easily lead to confusion. This paper puts forward Some proposals to surmount the conf fusion, and determines the relation between symmetry elements Sn and n and the relation between point groups n and Sn. According to the group theory standpoint 32 crystal point groups are to be divided into 7 crySta ystems. Each crystal system delegates the greatest subgroup, with other ssubgroups included in it. |
