摘要
介绍了国家标准《国家重力控制测量规范》的制定情况,并简要说明了规范中涉及的我国重力测量的等级、国家重力控制网的分级、绝对重力测量、国家级重力仪标定基线、重力点的联测精度、重力点坐标、高程测定的方法、数据处理以及重力基准与重力测量系统等内容。该规范不仅适应现代测绘科学技术的发展和满足国民经济建设、国防建设、空间技术、资源勘查、地震监测等领域的需要,而且对于地学及相关领域中的科学研究和工程建设也具有重要的作用。
This paper describes the things involved in the development of National Specifications for Gravity Control Measurement. It briefly presents the following aspects related to the Specifications, namely the orders used in gravity measurement in our country, the hierarchy of national gravity control network, the methods used in absolute gravity measurement, base line demarcation with gravimeter of national level, the accuracy of conjunction of gravimetric points, the coordinates of these points, and the methods used in height determining, as well as the method of data processing and the gravity datums and gravity measuring systems used in our country and many others. The above mentioned Specifications not only suit the development of modem surveying and mapping science, and meet the needs of national economic development, national defense building, space technology developing, resources prospecting and seismic monitoring and so on, but also plays an important role in scientific research and engineering construction in geo-science and many other related areas.
