GS型重力仪面板常数测定的研究

THE STUDY ON SCALE VALUE CALIBRATION OF GS-GRAVIMETER

摘要:

系统分析了GS-15-216重力仪多次在重力基线场标定的结果,并与厂家给出的面板常数进行对比,认为GS型重力仪的面板常数存在长期变化,应定期重新标定;检修或工作状态的变化也会引起面板常数的改变;面板常数是仪器测程的函数,必须分段标定以便拟合一条常数曲线.

Abstract:

Based on the systematical analyses calibration results of GS-15-216 gravimeter in base line field of gravity and the comparison between the results and the scale values provided by manufactory,it is shown that scale value of the gravimeter should be calibrated periodically because of its change with time,repairing instruments or changing work status would change the value and since scale value is a function of scale position,it must be calibrated one segment by one segment to fit a constant curve.
