摘　　要：整理淮北台2014年以来SS-Y伸缩仪观测资料,分析其在年、月、日和短时(数十分钟)不同时间尺度下对气压效应响应的差异,通过建立适当的数学模型拟合出相应的响应曲线,结果表明:在短周期时间尺度下SS-Y伸缩仪对气压效应的修正方程改进效果显著。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.
