摘要
本文针对GS型重力仪在记录格值标定中存在的问题,通过具体的格值标定试验和对试验结果的调和分析检验,得出:拉弹簧不同的格数和在不同的记录状态下测定记录格值,对标定结果是有影响的,前者的影响量为(1.1—1.6%),后者的影响量为(0.8—2.2%)。根据这种仪器的实际性能,本文推荐一种供参考的方法——拉弹簧10—15格,通过调节记录器零点位置或将输入到记录器的信号反向直接量图来测定记录格值。
Pointing to the problems existed in recording sensitivity calibration of GS-type gravimeter, through Practical calibration test of scale value and the check of harmonic analysis on the test result, a conclusion is made that both pulling the spring to different scales and measuring the recording sensitivity in different recording status have certain influence on the calibration results. The extent influenced by the former and the latter are(1.1—1.6%)and(0.8—2.2%)respectively. According to actual characteristic of such instrument,a reference method is recommended, which is pulling the spring by 10—15 scale intervals, then, determining the recording scale through adjusting the recorder zero position or reversely measuring the signal inputted into the recorder on the recording graph.
