国家重力计量参考网的初步建立研究

Preliminary Research in the Establishment of National Gravimetric Reference Network

重力加速度的计量有着非常重要的作用,不仅体现在计量科学和防震减灾等基础研究领域,还体现在压力、测力、衡器和大地测量等专业的实际应用领域。2016—2020年,中国计量科学研究院承担并实施了"重力计量专题服务"项目,项目组远赴西藏、新疆和香港等地区,顺利完成了50余个站点重力加速度的量值传递,初步建立了国家重力计量参考网。以后将进一步完善国家重力计量参考网。

The measurement of gravitational acceleration plays a very important role,which is not only reflected in the basic research fields of metrology science,earthquake prevention and mitigation,but also in the practical application fields of pressure, force measurement, weighing instrument, geodesy and other professional fields. From 2016 to 2020,China National Institute of Metrology undertook and implemented the project of "Gravity Metrology Special Service". The project team went to Tibet,Xinjiang,Hong Kong and other regions,successfully completed the transmission of gravity acceleration in more than 50 stations,and initially established the National Gravity Metrology Reference Network. In the future,the team plans to further improve the National Gravimetric Reference Network.
