三体问题是一个困扰学术界多年的难题. 自牛顿在《自然哲学的数学原理》中首次定义三体问题开始，人们已经在

这个问题上努力了300 年之久. 欧拉和拉格朗日先后研究了一些较为简单的三体系统问题，而庞加莱首先考虑了限制性的三

体问题，但发现其轨迹十分复杂而无法描绘. 他转而证明了三体问题不存在解析解，并着手创立了一门崭新的学科———非线性动力学. 充满生命力的非线性动力学或能为人们解决这个问题提供不同的思路.

Since Newton in the Mathematical Principles of Nature Philosophy for the first time to define three body problem，people have been working on this problem for 300 years. At first，Euler and Lagrange studied some relatively simple three -body system problems. Poincaré first considered the restricted three -body problem，but found that its trajectory is too complex to be described. He turned to prove that there is no analytical solution for the three-body problem，and created a new subject，nonlinear dynamics.
