较为详细地介绍了一种新的非线性、非平稳信号的处理方法-HHT(Hilbert-Huang Transform)方法,阐述了该方法的创新性,并对其有效性进行了数值检验.把该方法应用于新疆和田地电场台站和陕西西安地电场台站的观测数据,得到了各自的经验模态分解图、HHT时频图和相应的边际谱图,从这些图中可以清楚看出各自的频谱特征.最后阐述了HHT方法在地电场数据处理中的应用前景.

In this paper,we present a new method HHT(Hilbert-Huang Transform)which is invented to deal with non-linear and non-stationary data,and discuss its innovation and validity.We have applied this method to the observation data of the Hetian Geoelectric station and Xian Geoelectric station,and obtained diagrams of empirical mode decomposition,time-frequency and marginal spectrum about HHT.These figures show the spectral characteristics about two stations.Finally,the challenges and opportunities have been discussed about the application of HHT method to Geoelectric field data processing.
