通过对山东泰安基准地震台体应变仪记录的同震变化进行统计，绘制出了体应变映震能力图；2009-2012年全球共发生了91次7级及以上地震，仅有1例未记录，7级及以上地震记录能力为98．9％；其中，记录最小地震为3．5级，震中距165 km ；最远地震7．3级，震中距19498 km。同震变化幅度与震级成正比，与震中距成反比；并对地震前后出现的阶跃和畸变现象进行初步探讨，认为有些畸变可能与地震有关系。

By statistics of coseismic variation recorded at Tai’an Referential Seismological Station ,an formula of earthquake reflecting ability of body strain is figured out .Body strain at Tai'an Station has strong earthquake reflecting ability ,only one earthquake with M≥7 .0 missed .The magnitude of the minimum earthquake recorded is M=3 .5 with epicentral distance 16 .5 km ,while the farthest earthquake recorded is M=7 .3 with epicentral distance 19 498 km .Amplitude of coseismic variation is proportional with magnitude and is inverse with epicentral distance .Also ,step change and distortion ,which seem to be related with earthquake ,before and after earthquake are studied preliminarily .
