| 摘 要： | 用加卸载响应比理论对张北－尚义Ｍｓ６．２地震国卸载响应比随时间的变化进行了较详细的研究。结果表明，震前加卸载响应比有较明显的上升异常。异常出现的时间、异常幅度大小与所选择的区域有关，与所选取的震级下限有关，而且，还与发震构造和控震构造有关。异常与地震的对应关系表现为：上升异常出现，转折并恢复到正常值附近时发震。异常持续时间，短的半年以上，最长约６年左右。

| Abstract: | In this paper,by the load-unload response ratio theory,the variational characteristics of the load-unload response ratio before and after the Ms6.2 earthquake have been studied.The result showed that there was an obvious anomaly of the loas-unload response ratio before the earthquake.The influence factors to the anomaly include time,amplitude,selected region,magnitude lower limit,and seismotectonics also.The relationship between anomaly and earthquake showed that the earthquake occurred when the anomaly raised,turned and retumned to normal.The time of the anomly lasted half a year to six years. |
