中文说明：有十几个常用的微分动力学系统，可以直接运行程序包，计算李雅普诺夫指数，并绘制处变化曲线图，仿照例子，绘制自己模型的李雅普诺夫指数，并计算即可。
English Description：
There are more than a dozen commonly used differential dynamics systems. You can directly run the program package to calculate the Lyapunov exponent and draw the change curve. You can draw the Lyapunov exponent of your own model and calculate it by following the example.
