摘要
通过对拉科斯特重力仪稳定状态的分析,认为该仪器从断电至恢复供电后进入稳定状态的时间长短与断电、静置时间长短呈正相关。原因是重力仪核心部分的弹性材料的某些物理性质在不同温度下不尽相同。当工区转换时,仪器不能断电并尽量减少静置时间,以保证测量误差满足要求。
Through analyzing the stable state of Lacoste gravimeter,it is thought that the time,from breaking the electricity of the gravimeter to supplying electricity again to the meter entering stable state,shows positive correlation with electricity off time and the static time of the meter.This is because that the elastic material of the heart of the gravimeter is incompletely the same in physical feature at different temperatures.In order to reduce measurement error,the gravimeter can not be off electricity and statically placed too long when it is transferred from one working area to another.
