摘　　要：利用中日合作微震观测台网１９８８年３月至１９９１年３月间的地震记录计算了西安及周围地区小地震的波谱和震源参数，并探讨了震源参数与震级ＭL之间的关系.Using the small earthquake records from March 1988 to March 1991 from seismic network that was established jointly by China and Japan, source spectra and source parameters of small lo- cal earthquakes in Xi' an and its surrounding region are calculated and the relations between the source parameters and magnitude ML are analysed.
