本文具体讨论了使用蒙特卡罗模拟对氢原子三维 “电子云 ”进行可视化的方法．根据氢原子中电子的波函数，利用 Mathematica软件和蒙特卡罗模拟方法，实现了不同能级的氢原子三维电子云的可视化，使人们对氢原子中电子的行为有更加直观的认识．同时本文也给出了基于蒙特卡罗方法的研究一般原子系统，包括有微扰系统的电子云图像的普适算法，可用于量子力学可视化课程资源的进一步开发．

This paper introduces a method to visualize the three－dimensional “electron cloud”of hydrogen atom by Monte Carlosimulation． According to the wave function of the electron in hydrogen atom，the visualization of three－dimensional electron cloud of hydrogen atom with different energy levels is realized by using Mathematica software and Monte Carlo simulation method，which makes people have a more intuitive understanding of the behav-ior of the electron in hydrogenatom． At the same time，this paper also gives a universal algorithm based on Monte Carlo method to study the electron cloud image of the general atomic system，including the perturbation system， which can be used for the further development of the visualization resources for the courses of quantum mechanics．
