第十次作业
Continue the previous problem, and construct the phase-phase plots as in Figures 3.16 and 3.17 in the different regimes.
根据课本p76,可知球的运动方程为:
得到递推关系:
根据以上递推公式,即可编写程序。

Explore the intermittency route to chaos for in more detail. Begin by calculating as a function of time for different values of . Try (which shuould be in the nonchaotic regime), and several larger values up to or so. For larger values of you should observe chaotic "hiccups" like those study how it diverges as the transition to chaos is approached. While the idea here is easy to explain, writing a program to detect hiccups is a bit tricky. One way to accomplish this is to construct a histogram of times between adjacent maxima in . In the oscillatory (nonchaotic) regime these times will all be the same. An odd value signals a hiccup.
