| 摘 要： | 先对安装在湖州地震台"7号"人防山洞内的伸缩仪记录的线应变求得面应变,以及对安装在同一个山洞内的钻孔体应变仪进行气压消除后,对两者的同步观测数据进行对比和分析。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,观测到的地层面应变在固体潮频段具有可比性。

| Abstract: | In this article, plane strain data were obtained from the line side strain recorded by extensometer installed in No. 7 air defense cave of Huzhou Seismic Station, and the record of body drilling volume strain meter installed in the same cave, after eliminating gas pressure. Both synchronous data were compared and analyzed. Taking the strain solid tide of the Earth as the reference, it is found that the two types of data are basically the same strain and is proved that the surface strains observed by the two type equipments, with different length of the baseline and installation modes, are comparable in the band of solid tide. |
