中文说明：相空间重构是一种混沌时间序列的重要处理方法，而cao法则是计算相空间重构嵌入维数的重要方法，与G-P 平均位移法相比较，抗噪能力强，计算嵌入维数更加准确！
English Description：
Phase space reconstruction is an important processing method of chaotic time series, and Cao rule is an important method to calculate the embedding dimension of phase space reconstruction. Compared with G-P average displacement method, it has strong anti noise ability and more accurate calculation of embedding dimension!
