摘　　要：对加卸载响应比理论在地震预测中的应用进行分析,提出了对"正地震"和"负地震"震级根据加载库仑应力的半日潮振幅进行加权的研究思路,并应用于1999年台湾集集地震、2002年阿拉斯加Denali地震和2003年日本Hokkaido地震的震前加卸载响应比的计算。结果表明,相比较传统加卸载响应比,权重加卸载响应比更能突出震前的异常信息。After analysis to tile Load/Unload Response Ratio（LURR） theory and its application in earthquake prediction, I proposed the idea to weight the magnitude of the ＂positive earthquake＂ and ＂negative earthquake＂ according to the amplitude of Coulomb stress generated by half- day solid tides. I applied it to 1999 Chichi earthquake in Taiwan, 2002 Denali earthquake in Alaski and 2003 Hokkaido earthquake in Japan. The results show that the weighted LURR can make the anomaly prominent compared to the traditional LURR.
