摘　　要：利用坐标变换,导出对称轴的变换公式.对于空间群,利用布拉菲格子对对称元素的平移的限制,导出对称元素分布所需满足的条件,从而求出空间群对称元素的分布,并对空间群P4的对称元素进行分析.Based on the coordinate transformation, the formula of symmetry axes transformation is driven. For the space group, because Bravais Lattices restricts the symmetry factor's translation, the latter must satisfy the term driven, then the distribution of Symmetry Elements of space group in crystal structure can be got. By the role, the space group P4 is analyzed to get its Symmetry Elements.
