【摘要】 运用Mapsis软件前兆异常分析中的差分和从属函数,对新04号泉溶解气CO₂进行异常识别,结果认为:①差分和从属函数异常形态均为高值异常;②差分异常对近场中强震和远场强震的映震率均为71.4%（5/7）;从属函数异常对近场中强震的映震率为66.7%,而对远场强震的映震率为83.3%（5/6）;两者均出现异常时,对近场中强震的映震率为66.7%,对远场强震的映震率为100%（6/6）;③差分和从属函数的最大异常量与近场中强震的震中距基本成正比,可提高地震地点预报的精度。更多还原

【Abstract】 Using difference and subordinate function methods in mapseis soft,the anomaly of CO₂ in new No.04 spring is analyzed.The result shows that:①The abnormal configuration is positive anomaly;②The reflection earthquake ratio of difference anomaly is 71.4% for the medium -strong earthquakes in near region and strong earthquakes in far region;the reflection earthquakes ratio of subordinate function anomaly is 66.7% for medium-strong earthquakes, for strong earthquakes it is 83.3%;when the two kinds anomalies occurred,the reflection earthquake ratio is 66.7% for medium-strong earthquakes,it is 100% for strong earthquakes; ③It is direct ratio between the most abnormal range of difference and subordinate function anomalies and epicenter distance.This result can promote the precision of location prediction for earthquake.更多还原
