An R-space approach to the simulation and fitting of a structural model to the experimental pair distribution function is described, to investigate the structural disorder (distance distribution and stacking faults) in close-packed metals. This is carried out by transferring the Debye function analysis into R space and simulating the low-angle and high-angle truncation for the evaluation of the relevant Fourier transform. The strengths and weaknesses of the R-space approach with respect to the usual Q-space approach are discussed.

一种用于分析密堆积金属中堆垛层错的真实空间方法：G（r）建模和Q空间反馈。

描述了一种R空间方法，用于模拟和将结构模型拟合到实验对分布函数，以研究密排金属中的结构无序（距离分布和堆垛层错）。这是通过将Debye函数分析转移到R空间并模拟低角度和高角度截断以评估相关傅里叶变换来进行的。讨论了R空间方法相对于常规Q空间方法的优缺点。
