三、直接法和反常散射的结合1.引言1和2节所描述的传统直接法可以概括为:把原子散射因子作为(sinθ)/λ的任意复数函数,因而也就包括了存在一个以上反常散射原子的特殊情况。邻域概念再一次起着重要的作用。对两-相位和三-相位结构不变量的条件,概率分布理论所得出的最终结果作一简短的总结。特别是描述了在它们第一邻域给出的 III. THE COMBINATION OF DIRECT AND ABNORMAL SCATTERING 1. The traditional direct method described in Sections 1 and 2 can be summarized as an arbitrary complex function of (sinθ) / λ with atomic scattering factors and thus includes the existence of more than one anomalous Special case of scattering atoms. Once again, the concept of neighborhood plays an important role. A brief summary of the final results obtained from the conditions of the two-phase and three-phase structure invariants and the probability distribution theory is given. In particular, the ones given in their first neighborhood are described
