摘  要:计算机是当今信息化时代最重要的标志之一。计算机及计算方法的快速发展令计算机模拟变成物理问题研究中除了实验、理论分析以外的第三种研究方法。这种变化趋势肯定会反映到大学物理课程的教学里来。又因为日新月异的计算软件的强大性能，令学习计算机技术也成为一项轻松愉快的工作。原来在大学理论物理教学之中，对与一些不能够求解析解的常微分方程和偏微分方程，如今可以使用先进的数学软件，十分方便地去求解这些方程。在了解及掌握这些解法之后，不仅使能力得到了提升，同时还能更加深刻地理解问题的物理规律。换而言之，就是在物理教学之中有可能把理论物理的学习与用计算机通过数值计算来解决物理问题的能力结合起来，从而使问题的解决变得更加便捷。

   本课题的研究的是一个具体的一个问题，四个点初始位置是正方形的四个点，相互追击，使用计算机模拟的方式得到这四个点运动的情况。而使问题变得更加便捷直观。

Abstract:The computer is current information age the most important mark of. Computer and calculation method of the rapid development of computer simulation become physical problems that in addition to the experimental research outside, theoretical analysis of the third research methods. The trends will certainly reflected in university physics course teaching. And because of the changing the powerful performance calculation software, makes learning computer technology has become a relaxed and happy. Originally in theoretical physics from the university of teaching, with some can't ask for analytical solution of differential equation and partial differential equation, now you can use the advanced mathematics software, very convenient to solving these equations. In understanding and mastering these solutions, not only make ability after has improved, but also more profound understanding of a problem physical laws. In other words, is in the physics teaching in theoretical physics are likely to use the learning and using computer numerical calculation is the ability to solve the physical problems, so that combine the solution of the problem become more convenient. 

This topic research is a specific question, four points the initial position is square four points, mutual pursuit, USES the computer simulation way to get these four little exercise. And make the problem becomes more convenient intuitive.
