【摘要】 尝试对敦化地震台YRY-4型钻孔应变仪记录的应变地震波持续时间进行研究,以中国地震台网统一地震目录M_S≥7震级为参考震级,用最小二乘法求得参考震级公式:M_F-P=1.92+1.48 lg（F—P）。通过验证,公式有意义,为现阶段应变地震波的应用找到一条路径。更多还原

【Abstract】 In this paper,the duration of the strain seismic waves that recorded by model YRY-4 drill strain gauge of Dunhua Seismic Station is inverstigated tentatively.Taking China Seismic Network Catalog M_S≥7 as reference magnitude,calculating the magnitude of earthquake with the continue time of the strain wave in Dunhua Seismic Station,a reference magnitude formula M_F-P= 1.92 +1.48 lg（F—P） was obtained with least squares method.By analyzing the validation,the formula we got is meaningful.It provides a path for the application of strain seismic waves in this stage.更多还原
