摘　　要：计算混沌统计特征量前必须先获得重构相空间的维数,因此给出了最大特征值不变法、几何不变量法、虚假邻点法、预测误差最小法、最小Shannon熵法、经验赋值法六种确定方法,得出了应用最大特征值不变法和最小Shannon熵法的工程案例计算结果。It is necessary to get the dimension of re-constructed phase space before calculating the chaotic statistical. characteristics. Six methods are offered which are the measurement of the on unaltered maximal characteristic value, the measurement of changeless geometry mete, the measurement of false nearest neighbors, the measurement of minimum prediction error, the measurement of minimal Shannon entropy, and the measurement of the experience evaluation. An engineering case is given to explain the application of the measurements of the unaltered maximal characteristic value and minimal Shannon entropy.
