| 摘 要： | 本文根据特征离子坐标变化的特点,对黄铁矿型结构的微变化规律性进行了讨论。作了一些关系图,总结出结构中的MX。八面体随u值增加而愈接近正八面体,X(M_3X)四面体则随u值增加更扁平,并得出:成分的变化控制着u值的变化,u值的变化影响着晶体结构的微变化。

| Abstract: | This paper describes the microstructures of pyrite type compounds,and discusses the variation regularities of crystal struclure of pyrite type compounds in terms of variations in characteristic ion coordinates. Some diagrams are presented, including the diagrams of correlation between the u value of X anion and the (M-X)/a value, between the u value and the (X_7-X_1)/a value, between the (M-X)/a and (X_7-X_1)/a value et al. On the basis of the above discussion, some regularities are presented. |
