Rossler方程在一定的初直下是混沌的,用四阶龙格库塔方法画出系统状态图-Rossler equation is straight down at the beginning of a certain chaos, with fourth-order Runge-Kutta method to draw the system state diagram

用这个小程序可以解杜芬方程，可以通过相图判断混沌状态，判断加入噪声和信号-With this little program can Xie Duffing equation to determine the phase diagram can be chaos, judge by adding noise and signal

用matlab对duffing方程进行求解，duffing方程是混沌算法的主要分支之一，具有效果较为良好的微弱信号检测功能。-Duffing equation is solved using matlab Duffing equation is one of the main branches of the chaotic algorithm with a the effect weak signal detection function.

duffing方程的混沌判别中使用到了庞加莱截面，即多维相空间中适当选取一截面 ，此截面不与轨线相切，不包含轨线，且便于观察系统的运动特征变化.-use Poincare chaotic duffing equation discriminant, multi-dimensional phase space appropriate to select a cross-section, this section is not tangent to the trajectory does
