摘　　要：在X射线荧光分析中,X射线通常由电子打靶产生。基于MCNP蒙特卡洛方法可以模拟入射电子能量、材料、靶角、铍窗厚度、探测器大小、靶的尺寸等等因素对X射线能谱的影响,方便快捷,成本低廉。模拟结果可以在X射线管设计前期提供数据分析和技术支持。In X-ray fluorescence analysis, X-rays are usually generated by electron excitation. Monte Carlo Method can be used to simulate the effects of various factors, such as the incident electron energy, material, target angle, thickness of the beryllium window, detector size, and target size, on the X-ray spectrum. This method is convenient, fast and cost-effective. The simulation results can provide data analysis and technical support for X-ray tube design in the early stages.
