The paper also introduces the new process of gravimeter research in NIM. 還簡單介紹了中國計量科學研究院在這一方面研究的最新進展。

The density of the required data of astronomical measurement, gravimeter survey and geodesic survey is not satisfied. 需要的天文測量、重力測量、大地測量等數據的密度無法滿足其需要。

The Typical Absolute Gravimeter and the Atom Interferometer are the main equipments which measure the g directly. 摘要經典絕對重力儀和原子干涉絕對重力儀是目前國際上研制用來直接測量重力加速度值的主要精密計量儀器。

A micro-Gal absolute gravimeter based on high-precision and high-stability heterodyne interferometer is presented. 本文提出的微伽絕對重力儀基于高精度、高穩(wěn)定的差動干涉儀。

The value of gravimeter surveys for gravity-change detection lies in the fact that gravity change indicates elevation change. 用重力測量檢測重力變化的意義在于，重力變化表示高程變化。
