Abstract：This paper describes the geological characteristics and core physical characteristics of the body strain gauge TJ-II in Xiaotao seismic station,and introduces the operation of TJ-II body strain meter in Xiaotao seismic station. The paper uses the tide factor of M2 wave and the relative errors to measure the overall accuracy and stability. Based on the analysis of the characteristics of the coseismic effect and short impending anomaly of observation data from the TJ-II over the past year,the practical significance of the study on the prediction of the future middle strong earthquakes in the future of the small pottery area is preliminarily discussed.
