具有VRL8350静电反馈装置的拉科斯特重力仪性能的研究

A STUDY OF THE LCR GRAVIMETER WITH VRL 8350 FEEDBACK SYSTEM

1983年,美日科学家Harrison和Sato发展的一种静电反馈技术成功地用于拉科斯特流动重力仪,使这一技术迅速推广到世界各国。本文将讨论具有VRL 8350静电反馈装置的拉科斯特重力仪的线性问题,研究拉科斯特重力仪在非反馈和反馈条件下,仪器纵水泡对重力仪的灵敏度、固有周期和阻尼的影响。

So far, more than ten LCR gravimeters, both model G and D, have been transformed with feedback system VRL 8350 (1985) according to the Harrison-Sato method (1983). We discuss here the linearity of the LCR meter with the feedback system. Moreover, the eigen period, damping and sensitivity with respect to the longitudinal level have been investigated under various conditions, with and without feedback.
