摘　　要：提出了一种分析未知晶体对称性的新方法,并给出了此种方法对二维晶体应用的结论.过去人们可以通过未知晶体的晶格图,根据尼格里胞间接得到未知晶体所属的布拉菲格子.但是这个新方法不同于尼格里方法,它能够更方便地得到相同的结论.同时提出了配位形这个新术语.A new method to research the symmetry of unknown crystal is presented and a conclusion on two-dimension crystal structure concerning this method is arrived at. In the past, Niggli's cell could be used to obtain indirectly the type of Bragg's lattice to which the unknown crystal lattice belongs by crystal lattice pattern, but this new method is different from Niggli's, in that, it can directly and conveniently get the same result, and also a new term, coordination shape, is coined in this article.
