| 摘 要： | 如果重原子具有高于结构的赝对称性,使用重原子法应获得具有多解形式的轻原子位置,我们引入一个赝结构模型并导出了赝结构衍射结构因子FM(H)的表达式,给出了校正项|EP(H)|的估算值。将多解型重原子法应用于一个未知结构,获得了完美的赝结构图象。

| Abstract: | We applied the heavy atom method to obtain the light atom positions of multi-solution type in the case of heavy atoms possessing a pseudo-symmetry whiCh is higher than that of the who'e structure. We introduced a model of pseudo-structure, derived an expression of diffraction structure factor FM(H) for a pseudo-structure and gave an estimate of correction term |EP(H)|.When we apply the heavy atom method of multi-solution type to a known structure, a perfect pseudo-structure pattern in obtained. |
