摘　　要：传统地电阻率观测对地震长趋势预测有一定的效果,但短临信息的提取研究仍需加强,而地电潮汐力谐振共振波(the harmonic resonance waves of geo-electricity driven by tidal forces,简称"HRT波")方法,则是利用地电前兆的波动特征,进行地震短临信息提取的一种新尝试.本文首先对HRT波进行了的简单介绍;其次,从唐山地震前地电阻率观测出现异常开始,通过异常现象与起潮汐力的相关性研究,地电临震前兆起潮力模式的建立,以及印尼9.0级等地震的分析研究,对HRT波的发展历程进行了回顾;最后,借鉴汶川地震的一些实际工作,介绍了如何使用HRT波对震中距和震级进行预测的方法.此外,结合学习研究HRT波过程中,对潮汐力谐振波(Harmonic waves driven by tidal forces,简称HT波)的提取方法问题、建议使用数字信号处理技术进行,对潮汐力共振波(the resonance waves driven by tidal forces,简称RT波)不容易辨识的问题,仍需进一步探索研究.参考该方法在一些具体工作中的表现,指出该方法在短临信息的提取上有一定的创新性,可以对未来地震提出较为准确的短临预测意见,如果将常规地电阻率观测与PS100地电观测相结合,将是非常好的研究方向.By using the traditional geo-electric resistivity,some progresses have been achieved in predicting the long trend of future earthquakes,but that’s still needed to be strengthened at the shortimpending information extraction. Now,the harmonic resonance waves of geo-electricity driven by tidal forces（ HRT wave） method,which uses the fluctuation characteristics of geo-electric precursors,is a new attempt to extract the short-impending information for impending earthquakes. In this paper,a simple introduction about the HRT wave will be carried out firstly; and then,by the study on the correlation between abnormal phenomena and the tidal forces,the establishment of geo-electric precursory short-term anomalies driven by tidal forces model and the analysis of magnitude 9.0 earthquake in Indonesia,etc,we reviewed the development of HRT wave method since the earth resistivity anomalies were observed before Tangshan earthquake. Finally,referencing some practical work of Wenchuan earthquake,we introduce how to use HRT wave method to predict epicenter distance and magnitude. In addition,we suggest that it’s better to use digital signal processing technology to extract the harmonic waves driven by tidal forces（ HT wave） from our study on HRT waves. Besides,it calls for more research on the recognition of the resonance waves driven by tidal forces（ RT wave）. After applying HRT wave method to some concrete work,we pointed out that this method which has some innovation in the extraction of short-term information can provide us more possibilities on earthquake short-term prediction in the future. Furthermore,if we can combine conventional earth resistivity observation with PS100 earth resistivity observation, it will be a very hopeful research area.
