说明：  一个画一种Logistic Map 分岔图(bifurcation diagram)的程序，运行后，你们可以看到它与常规的非线性系统的行为不一样。该映射可以用如下方程表述: xn=1-a*x2n-1 其中，a――[0,2].
(Logistic Map a painting of a bifurcation diagram (bifurcation diagram) procedures, running, you can see it with the conventional non-linear system behavior not the same. The mapping equation can be expressed as follows: xn = 1-a* x2n-1 of them, a- [0,2].)
