摘　　要：研究作为质点的三个天体在万有引力作用下的运动,即所谓的“三体问题”是天文学及相关物理学和数学等领域的重要科学问题。因为三体系统是一个不稳定系统,而且三体问题在数学上没有解析解;所以三体问题解的其他数学物理表达及高精度数值分析中会涉及复杂的理论公式和方法。本文针对天文学通识课上,普通听众对于常规理论化的三体问题讲解很难理解甚至觉得索然无味的问题,研发了一套三体运动可视化软件。软件可以对经典和最新的三体问题特解进行可视化呈现,也可根据用户设定的三体参数进行可视化展示。该可视化软件已应用于天文学通识课程的教学,取得了较好的效果。相关软件和教学成果可为涉及三体问题教学的通识课程提供参考。The three-body problem is an important scientific issues in the fields of astronomy and their related physics and mathematics etc.Because the three-body problem is not ana⁃lyzed in mathematics,and the three-body system is an unsta⁃ble system;the mathematical physical expression and related numerical analysis of the three-body problem will involve com⁃plex theoretical formulas and methods.When we teach the three-body problems in the general courses with those theory teaching methods,the general listeners are difficult to under⁃stand it and feel tasteless.In this paper,a set of visual threebody demo software was developed.The software can per⁃form visualization of classics and those new three-body prob⁃lems special solutions,or perform visualizations based on the three-body parameters set by the users.This visualization software applies to the teaching activities of astronomical in⁃structional general courses,and has achieved better feed⁃backs.This software and teaching experiences can be refer⁃enced to those relevant three-body teaching activities.
