摘　　要：以乾陵台地倾斜、地应变观测为基础,研究了自2001年数字化记录以来有同震记录的分钟值观测曲线,探讨了同震形变响应的物理特征,结果表明面波延迟时间、同震最大变幅、持续时间等与各个地震的震级、震中距存在一定程度的线性或正比分布关系;同震衰减特征与地震参数、仪器性能、地基结构等因素有关。On the basis of the digital observation of crustal tilt and ground strain at Qianling seismostation, the digital records of the minutely co-seismic observation curves since 2001 are studied and the physical characteristics of co-seismic deformation responses are studied. The results show that there are linear or proportional distribution re- lationship in a certain degree between the delay time of surface wave, the biggest shock, duration, and the magni- tudes, the epicenter distances of all earthquakes. Besides, the coseismic attennation characteristics are related to some factors such as earthquake parameters, instrument performance, foundation structure.
