| 摘 要： | 根据漳州地震台深井观测系统中探头上、下端面共8分量应变观测单元及台站洞体内伸缩仪的应变固体潮观测资料,利用相互垂直的一对线应变分量共5种组合的方式计算出本地的面应变，并与固体潮理论值进行两两相关分析比较。结果表明，深井观测系统的4种面应变组合的变化形态较伸缩仪面应变更接近固体潮面应变理论值，其中6#8#组合为最优组合，与固体潮理论值相关系数高达0．9418，而伸缩仪组合与理论值相差较大，相关系数仅为0．7838。Venedikov调和分析显示，深井观测系统的内在质量优于洞体内伸缩仪的观测质量。

| Abstract: | According to strain tide observation data of 8-component strain meters unit in the deep bore observation system and extensometer in the cave in Zhang Zhou seismic station, we make use of a pair of line strain components which are orthogonal and have totally five assembles to calculate plane strain of Zhangzhou City and compared with the solid tidy theoretical value. The result shows that the shape change of four kinds of plain strain assemble of deep bore observation system is more close to the earth tide theoretical value than the extensometer. Among of them, the 6#8# assemble is the best and the coefficient is about 0. 941 8, while the theoretical value with extensometer comparatively large, the related coefficient is 0.783 8. The Venedikov harmonic analysis shows that the inherent quality of deep bore observation system is better than observation quality of extensometer in the cave. |
