摘　　要：通过对乌鲁木齐地震台宽频带数字地震仪记录的具有代表性、典型性的地震波形震相分析,展示乌鲁木齐地震台宽频带数字地震仪记录波形震相特征,找出快速判定震相的方法,进一步提高大震速报质量。In this paper, reprehensive and typical earthquake waveform recorded by a wide digital seismograph of Urumqi Seismic Station is analyzed and phasic character of the waveform is demonstrated. A method of rapid determination of earthquake is found out, which could improve the quality of rapid earthquake alarm.

关 键 词：宽频带数字仪记录 波形震相特征 大震速报
