摘　　要：对代县地震台体应变观测数据与气压的相关性进行分析,得出其相关系数,表明两者的相关性显著,气压对观测数据存在明显的影响;经一元线性回归处理后,去除气压影响的观测曲线幅度明显变小、更光滑,说明用此法可排除气压造成的影响。The correlation of volume strain observation data and the barometric pressure in Daixian Seismological Station is analyzed to obtain the correlation coefficient.The results show that the correlation between the two is significant,and the barometric pressure has a significant effect on the volume strain observation data.After the simple linear regression processing and removing the influence of barometric pressure,the amplitude of the observation curve is obviously smaller and the curve is smoother.It indicates that this method can remove the effect of barometric pressure.
