摘　　要：用"剥皮法"处理了腾冲地震台2002年1月至2008年8月视电阻率数字化观测资料。结果表明:"剥皮法"反演计算速度快且稳定;反演后的资料明确显示深部电阻率存在明显变化,这一变化与地表气候及人文干扰无关,可能与2008年5月12日汶川8.0级地震有关。Using the ＂peeling method＂, we processed the digital observational data of apparent resistivity from Jan. , 2002 to Aug. , 2008 in Tengchong Seismic Station. The results showed that the inversion process of ＂peeling method＂ possessed fast calculation speed and stable. Inversion result showed that there exited evident changes of resistivity in deep layers. Those changes weren＇t associated with the interference of climate change and humanity activities, and might be associated with Wenchuan Ms8.0 earthquake in May 12, 2008
