And then, in the foundation of the overseas scholars'study, I study RP and the CRP methods for visualization the dynamics characteristic of the phase space track as well as the complexity degree algorithm of chaos time series——ApEn algorithm. Applying these two methods based on the VB program we analyze separately the data which is obtained from complex financial system model and Lorenz system, and obtain several new recurrence plots and cross recurrence plots. This provides the graph gist of determination complex intrinsic characteristic. The results establish the foundation for exact and further division of chaos time series.

接下来，在国外学者研究的基础上，基于混沌时序形象化相空间轨迹的动力学特征的分别研究了RP和CRP方法以及判定混沌时间序列的复杂度算法的ApEn算法，基于VB程序应用这两种方法分别对Lorenz系统及实际的一类复杂金融系统模型所得到的数据进行了分析，得到了几个较为新的复原图和相干复原图，这对于判定时序数据的复杂内在特性提供了图形上的比对依据，研究结果为混沌时序的准确和进一步分类奠定了基础。
