摘要
通过新疆温泉地震台FGM01磁通门磁力仪资料和温度资料,经相关分析和回归分析发现:温泉地磁台地磁场各分量子夜均值与探头温度相关系数较高,存在准线性关系,回归分析能够有效的剔除温度影响;通过回归残差分析,可以看出温泉地磁场存在年周期、半年周期变化;垂直分量Z子夜均值的回归残差与同一观测点形变资料存在同步变化,在一定程度上提取与地下介质变化有关的信息。
Based on the data of FGM-01 fluxgate magnetometer and temperature data of Xinjiang Wenquan Seismic station,through correlation analysis and regression analysis,it is found that the midnight mean value of each component of hot spring geomagnetic field has a high correlation coefficient with the probe temperature,and there is a quasi linear relationship,so regression analysis can effectively eliminate the influence of temperature;through regression residual analysis,it can be seen that the hot spring geomagnetic field has an annual cycle and a half year cycle The regression residuals of z-midnight mean of vertical component have synchronous changes with the deformation data of the same observation point,and the information related to the change of underground medium has been extracted to a certain extent.
