| 摘 要： | 利用相位随机化的替代数据方法可对动力系统实测时间序列数据的随机或混沌特性进行判定。本文对服从不同分布的随机数相位随机化后对动力系统实测数据生成的替代数据及其所对应的判值的影响做了分析研究。计算结果表明：不同分布的随机数相位随机化后对临界值无质的影响，从而进一步论证了相位随机化方法的可行性和实用性．

| Abstract: | Surrogate data method of phase-randomized is proposed to identify the random or chaotic nature of the data obtained in dynamic analysis. In this paper, the influence of critical value by the different distributed phase-randomized to the data obtained in dynamic analysis is studied. The calculation results validate that the phase-randomized of the different distributed random number is less influence for the critical value. This offer the foundation of the feasibilty and practicality of the phase-randomized method. |
