摘要

如果帕特森函数的和项仅包含卫星反射，则可以揭示基本结构的调制。各种类型调制结构的帕特森求和的例子说明了解释的困难和在确定调制的幅度和相位时发生的偏差。讨论了利用帕特森函数确定调制结构的可能性。

Limits of the Patterson Method for the Determination of one-dimensionally Modulated Structures

The Patterson function can reveal the modulation of a basic structure if its summation terms include only satellite reflections. Examples of Patterson summations for various types of modulated structures illustrate the difficulties of interpretation and the bias occurring in the determination of the amplitudes and phases of the modulation. The opportunity to use the Patterson function to determine modulated structure is discussed.
