X-Light is an open-source software that is written in Python with a graphical user interface. X-Light was developed to determine residual stress by X-ray diffraction. This software can process the 0D, 1D and 2D diffraction data obtained with laboratory diffractometers or synchrotron radiation. X-Light provides several options for stress analysis and five functions to fit a peak: Gauss, Lorentz, Pearson VII, pseudo-Voigt and Voigt. The residual stress is determined by the conventional sin²ψ method and the fundamental method.

X-Light：一个用 Python 编写的开源软件，用于通过 X 射线衍射确定残余应力

X-Light是一个开源软件，用 Python 编写，带有图形用户界面。X-Light被开发用于通过 X 射线衍射确定残余应力。该软件可以处理使用实验室衍射仪或同步辐射获得的 0D、1D 和 2D 衍射数据。X-Light提供了多种应力分析选项和五个拟合峰值的函数：Gauss、Lorentz、Pearson VII、pseudo-Voigt 和 Voigt。残余应力由传统的 sin ² ψ 法和基本法确定。
