摘要
概述了两种不同类型的静电反馈装置的基本原理，介绍它们在区域重力测量、微重力测量、垂直梯度测量、固体潮观测和周期误差标定等方面的优越性及实际应用效果。根据四台仪器的标定实践，研究了反馈系统的线性度检测与调整和转换因子的标定问题。最后提出了还有待研究的几个问题。
The basic principle of two kinds of electrostatic feedback instruments are described in this poper.The effects of application of electrostatic feedback instrument to the regional gravity measurement,the microgravimetry,the vertical gradient measurement and Earth tide survey are reported.Besides,according to the calibration of 4 gravimeters,it was studied to inspect and adjust the linearity of the feedback system and calibrate the translation parameters.Finally,some problems which need to be studied in future are presented.
