本文对泰安台所使用的SQ-70型石英倾斜仪的格值变化情况作了较为深入的讨论。一年中,该台东西向格值变化为11.0×10~(-6)秒/毫米,南北向格值变化为13.0×10~(-5)秒/毫米。东西向格值变化与南北方向倾斜量间相关系数为0.96;南北方向格值偶而变化较大,与开壁龛门调摆,壁龛内温度场的分布情况改变有关。本文还将格值变化对v值的影响及利用格值变化规律鉴别震兆异常作了分析。
This article made a more in-depth discussion on the variation of grid values of SQ-70 Quartz Inclinometer used by Taian Station. In one year, the tidal range of the east-west trellis varied from 11.0 × 10 ~ (-6) s / mm and the north-south trellis varied from 13.0 × 10 ~ (-5) s / mm. The correlation coefficient between the east-west trellis and the south-north trending tilt is 0.96. The trellis values change occasionally in the north-south direction, which is related to the changes of temperature distribution in the alcove. This article also will grid value changes on the v value and the use of grid values to identify changes in the rules of earthquake anomalies were analyzed.
