老虎吃兔子是一个典型的非线性系统，当老虎数量多的时候，兔子就容易被吃，兔子数量减少，兔子数量较少，老虎捕兔困难，老虎就饿死，老虎数量减少后，兔子繁殖加快，从而使得兔子数量增加，老虎捕食又变得容易了。利用C语言编程、利用４阶龙格－库塔法就可验证老虎与兔子的非线性生态现象。-Tiger eating rabbit is a typical nonlinear system, when the tiger population and more often, it is easy to be rabbit food, rabbit decrease in the number of rabbit small number of rabbits caught tiger difficulties, tiger starved to death, reduce the number of tigers, the rabbit breeding to speed up, resulting increase in the number of rabbit, the tiger has become easy prey. The use of C language programming, using 4-order Runge- Kutta method can verify the tiger and rabbit non-linear ecological phenomena.
