摘　　要：在管道流场中,基于希尔伯特黄变换(HHT)的非平稳信号的处理分析已经成为了目前的研究热点,从管道流场中流体信号的去噪、流型识别以及流体动态特性等方面综述了HHT的应用情况,分析了IMF能量与流体运动特性的内在关系。提出了采用流体运动的状态参数进行分析流体湍流运动的内在机理的新方法,并对管道流中流体运动规律的研究进行了展望。In the pipeline flow field,the processing analysis of non-stationary signals based on Hilbert-Huang Transfor(HHT)has become a hot research topic.The application of HHT is reviewed from the aspects of denoising,flow pattern identification and fluid dynamics of fluid signals in pipeline flow field,and the intrinsic relationship between IMF energy and fluid motion characteristics is analyzed.At the same time,a new method for analyzing the internal mechanism of fluid turbulent motion using state parameters of fluid motion is proposed,and the research on fluid motion law in pipeline flow is prospected.
