| 摘 要： | 应用加卸载、差值、斜率法及小波分析等方法，对陕西各地磁台的资料进行处理分析，结果显示：关中地区较大范围内的地磁场变化稳定；泾阳台、乾陵台的地磁场，在昆仑山口西8．1级地震前存在异常现象，且对省内近期发生的ML4．0以上地震有前兆反映。

| Abstract: | Based on load-unload response ratio, difference value, gradient and wavelet analysis method etc, the magnetic datum are processed and analysed at all geomagnetic stations in Shanxi province. Results show that the geomagnetic field is stable at large extension in Guanzhong region. The geomagnetic field occurred abnormal at Jingyang and Qianling stations before the earthquake 8.1 at west of Kunlun Mountain, moreover, these regions occurred precursor abnormal before the ML 4.0 of recent occurrence in Shanxi province. |
