Simulation of X-Ray Diffraction Profiles By Computer

摘要: 提出一种模拟X射线衍射线的方法，即在构造Voigt函数的基础上叠加服从泊松分布的随机数，并对模拟结果进行统计检验，以考察它是否符合泊松分布，同时考察是否可把模拟衍射线与实测衍射线看作来自同一个总体。结果表明，可用模拟衍射线代替实测衍射线。并用实例说明如何应用模拟衍射线来解决实际问题。

Abstract: A method to simulate X-ray diffraction profiles by using Voigt function and Poisson distribution was established. The statistical evaluation showed that the measured and the corresponding simulated X-ray profiles could be viewed as coming from the same parent population. Results demonstrated that the simulated profiles could be used to replace the measured ones and to solve such problems as evaluation of absolute errors in analyzing X-ray diffraction profiles.
