| Abstract: | According to the observation data of SS-Y extensometer at Huaibei Seismic Station since 2014,the differences of its response to air pressure effect in different time scales of year,month,day and short-time(tens of minutes)are analyzed.And by establishing appropriate mathematical model,a corresponding response curve is fitted.The results show that the modified equation of pressure effect can be improved obviously by SS-Y extensometer in the short-time scale. |
