摘　　要：体应变仪数字化后,虽然采样率为分钟值,但也能较清晰地记录到一些远大震的应变波,怎样分析、认识体应变应变波的形态、特征,用应变波计算对应地震的震中距和震级是需要分析、尝试的。本文利用2011年3月11日日本本州东海岸附近海域9.0级地震,分析体应变记录的同震应变波特征,计算出震中距和震级。Our volume strain instrument is a digitalized one and its sampling rate is one per strain wave recording of the 2011 Off the Pacific Coast of Tohoku 9.0 earthquake is clear. characters of the volume strain wave and then use the volume strain wave recording of the 2011 of Tohoku 9.0 Earthquake to calculate the epicenter distance and the earthquake magnitude. minute.
