我国地球形状及重力场研究的进展

本文总结了我国解放三十年来重力学上的成就。首先叙述了我国普遍重力测量工作。此外,围绕天文大地测量网的天文点周围进行了十分密集的重力测量,以保证天文重力水准计算的精度。还进行了作为地球物理勘探及其他科学研究昕用的重力测量。由天文重力水准所得的天文大地高程异常图已经完成,空间异常及布格异常图正在编制之中。在理论研究方面,也进行了不少的工作。

RESEARCHES ON GRAVIMETRY AND FIGURE OF EARTH IN CHINA

The paper summarizes the gravimetrieal works which were done during the 30-year's period after the founding of the People's Republic of China. First of all, we have accomplished the general gravity survey throughout the country. Besides, very dense gravity surveys were carried out around the astronomical points of the astro-geodetic nets, in order to provide the, precisions for the calculations of the astro-gravi-metric levellings. Other surveys were also done for special purposes, such as for geo-physical prospectings and other scientific researches. Maps of astro-geodetic height anomalies obtained by the astro-gravimetric levellings were completed. Maps of free-air and Bouguer anomalies are now under compilation. For the theoretical researches, lots of works have also been carried out.
