| 摘 要： | 对银川台所使用的SQ－70型石英摆倾斜仪的格值变化作了较深入的分析。一年中该台南北向格值平均变化0．160×10^-3″／mm，东西向格值平均变化0．133×10^-3″／mm，2个测向的格值变化与其倾斜量、洞体室温之间存在显著相关性。同时还将格值变化对γ值的影响作了分析。

| Abstract: | In this paper, the calibration＇ s change of the tiltmeter with quartzferous pendulum used in Yinchuan station is analyzed. In one year, the average change of the calibration in the NS direction is 0. 160 × 10^ -3″ / mm, and EW is 0. 160 × 10^-3″/mm. The calibration＇ s changes of the two directions have obvious correlat- ability with their tilt value and the cave temperature. |
