摘要
本文介绍了我国自行研制的新的轻小型高精度可移式绝对重力仪NIM-3型的测量原理，采用的新技术方案和仪器结构的主要特点。同时文中给出用本仪器几个典型测量结果及其准确度优于±1×10^(-7)m/s^2（±10μgal）。
This paper describes a new type NIM--3 transportable absolute gravimeter devel-
oped by National Institute of Metrology of China. It is a gravimeter of small size and
light weight. The operational princip1e. the technical scheme adopted. and the main fea-
tures of construction are given.
A number of typical measurement results obtained with this gravimeter within Chi-
na are presented. The accuracy is superior to ±10μgal.
