| Abstract: | According to the working principle of the SS-Y tensometer,this article analyzes disturbance characteristics from air pressure change of Huaibei seismic station.The results show that air pressure is the main interference on the extensometer, and the relation between the SS-Y tensometer and air pressure is direct ratio. Through quantitative analysis, mathematical formulas are established to catch tensometer and air pressure change disturbance. |
