| 摘 要： | 运用mapsis软件前兆异常分析中的差分、从属函数等计算方法对新10号泉硫化物测值进行异常识别。结果表明：（1）差分和从属函数异常以高值异常为主;（2）差分异常对应近场MS≥5地震对应率为100%（6/6）,对远场MS≥7地震对应率为66.7%（4/6）;（3）差分和从属函数异常最大量对近场MS≥5地震的震级和震中距相关性不明显;（4）差分和从属函数异常有一定同步性。

| Abstract: | Using difference,subordinate function methods in Mapseis soft to analyze the abnormal change of sulfid in New No.10 spring,the result shows,（1）the abnormal shape is high value anomaly;（2） the difference abnormity is high value for the earthquakes with MS≥5 in the near region,low value for the earthquakes with MS≥7 in the far region;（3）the relation between max-value of abnormity and magnitude,epicenter distance of MS≥5 earthquakes is not evident;（4）there is certain synchronicity between difference and subordinate function abnormity. |
