摘　　要：应用地震前周、月会商中各前兆手段提出的短期前兆异常动态变化，研究了地震短临异常的某些特征和综合预报指标。其最大的特点是应用在不知未来是否有地震的情况下提供的短期异常，总结了地震预报的经验。所以，是从一个新的角度研究的，而不同于以往的震例总结。因此，该经验更接近于日常实际的预报，可能更具有实用性。Some features and comprehensive indexes of anomalies appeared just before anevent are studied based on dynamic changes of the short- term precursor provided by theweekly and monthly discussion meeting. The most noticeable benefits of the methodmentioned here are to obtain earthquake prediction experiences while not sure whetherthe event would occur. Therefore, our results been gained in a new way, which is different from the previous results by using the old methods, The experience from the re-search is closer to the real prediction circumstance and more useful.
