基于改进的广义S变换，能更好的对数据进行时频分析。-Modified S-transform and its application in data analysis

广义S变换及其逆变换，用于对非平稳信号进行时频分析，研究信号的频域特征随时间的变化情况(The generalized S transform and its inverse transform are used to analyze the time-frequency of nonstationary signals and study the change of frequency domain characteristics with time.)

广义S变换，用于时频分析，是S的改进形式(Generalized S-transform, used in time-frequency analysis, is an improved form of S)
