相变量 meaning in English

phase variable

A real physical system may involve many variables but only one or more of them can be detected by modem data collecting equipment in recent years , the technique of phase space reconstruction is frequently applied to analyse and process time series . its significance is that the topological characteristics such as fractal dimension can be obtained , on the basis of investigation and research about the technique of phase space reconstruction up - to - now , this paper is also devoted to develop a new method for the prombles of detecting deterministic chaos of time series obtained from experimental data
一个实际的系统可能会涉及多个相变量，但在实际问题中只能得到部分相变量的信息，近年来人们发展了相空间重构方法，能够通过单变量信息重构吸引子，这种方法在时间序列分析和处理中得到广泛应用，其意义在于能在拓扑等价意义下恢复吸引子的拓扑特征，本文第三章在国内外有关时间序列的相空间重构研究状况基础上，致力于发展对时间序列进行确定性检验的新方法，即研究时间序列的分布规律和赫斯特指数，并在相空间重构的基础上，提取吸引子的特征指数。
