| 摘 要： | 加卸载响应比理论具有雄厚的物理基础，取太阳日照（或磁暴）过程作为加卸载，地磁垂直分量Z为响应，选取了山西临汾、太原、内蒙古呼和浩特地磁台1987年1月至1998年12月的相对观测资料，计算出其响应比值P（Z）的变化。发现P（Z）异常与周围700km范围内发生的Ms≥5．5中强地震有较好的对应关系，并对计算结果及其在地震预报中的应用进行了分析探讨。

| Abstract: | Loading and unloading theory is reasonable physically. In this study, the procedure of sunshine (or magnetic storm) is taken as the loading and unloading and its response is the vertical geomagnetic component . The changes of the response ratio
P(Z) is computed based on the geomagnetic data of L infen,Taiyuan and Hohhot stations. The result shows that the precursors of P(Z) are fairly well related to the earthquakes of M s≥5.5 within the radius of 700km. Also,how to apply this method to t he earthquake prediction is discussed. |
