摘　　要：１９９６年３月～１９９８年８月期间，伽师地区发生１１次包含６级以上地震的强震群，震前，北天山地区硫化物出现了明显的强震远场效应，并认为硫化物生成过程中明显受到压强的影响是硫化物能形成强震远场效应的最重要原因。From March 1996 to August 1998,a series of strong earthquake swarms including 11 earthquakes with Ms≥6.0 occurred in Jiashi area.Before the earthquakes,plain changes of sulphides in the north Tianshan area have been observed.It is considered that sulphides are influenced by the pressure during the process in which the sulphides are produced is the important reason of far-field affects caused by sulphides.
