| 摘 要： | 对同一地震所激励的伸缩仪和体应变仪的体应变响应进行了对比分析,结果表明,这两个观测系统所记录到的是叠加在体应变固体潮背景上的一种振荡衰减变化。这两个系统分别对发生在印尼、中国台湾和福建的几次远震、地方震和近震作出了不同程度的响应。体应变响应幅度约为10-7～10-9,并且体应变仪的响应幅度大于伸缩仪的。同一观测系统的响应幅度与地震能量成正比,响应延迟时间与震中距成正比。 |

| Abstract: | We conduct a comparative analysis of volumetric strain response of extensometer and the volumetric strain response of body-strain gauge to the same earthquake.The two observational systems recorded an oscillating attenuation change overlaying the background of the solid tide of volumetric strain.The two systems differently response to Indonesian distant shock,inland earthquake and Taiwan earthquake.The magnitude of volumetric strain response of these two systems to the earthquakes varies from 10-9 to 10-7.T... |
