| 摘 要： | Ｗｉｎｇｅｒ分布中互谱项严重影响了其物理解释及其应用。本文在分析Ｗｉｇｎｅｒ分布互谱项的特征后，讨论了消减互谱项的方法，并应用于机械状态监测实际信号分析中，机械特征相当明显，且得到了较为理想的时一频分布结果。

| Abstract: | Cross items in Wigner distribution have a great influence on its explanation and application.This study was designed to analyze the features of cross- items in Wigner distribution and to discuss vanons methods to eliminate cross-items. These methods are used in signal analysis experimentS and moresatisfactory time--frequency distribution results are obtained. |
