摘　　要：本文对先后安装在营口地震台的伸缩仪和分量钻孔应变仪的同步观测数据进行了比对和分析。以地球应变固体潮为参照,确定两种应变观测数据基本一致。证明这两种基线长度和安装方式不同的仪器,观测到的地层应变在固体潮频段具有可比性。In this article we have made analyses and comparisons of synchronized data from an extensometer and a 4-component borehole strainmeter at Yingkou seismological station. We used solid earth tide as the reference strain, the strain data from these two instruments are basically identical. That concludes these instruments with different baseline and different working principle, can observe comparable earth strain in the solid tidal band.
