摘　　要：在对地下流体单项前兆进行异常识别和效能评价的基础上,应用综合异常指数方法对新疆38项地下流体前兆观测资料进行分析,结果表明该方法不仅能较好地识别和提取地震短临前兆,还能对成组地震事件有所显示。Based on the anomaly distinguishing and efficacy evaluation of single underground fluid precursor, 38 kinds of underground fluid precursor data in Xinjiang were analyzed by synthetic anomaly index method. The result shows that the method is not only good at distinguishing and abstracting short-term and impending-earthquake precursor, but also can be used to judge grouped seismic events. It supplies a method for comprehensive underground fluid prediction and short-term, impending-earthquake anomaly tracing.
