近两年来,随着高精度绝对重力值测量工作的开展,在我国苏、鲁、皖,京、津、唐及云南等地相继布设了绝对值重力测量与相对值重力测量相结合的高精度重力监测网。重力网平差的基本计算元素由以前单一的段差值变为绝对重力点观测值与段差值两部分。由此而产生的一系列新的技术问题引起了重力测量工作者的兴趣与关注。 In the past two years, with the development of high-precision absolute gravimetry, high-precision absolute gravimetry and relative gravimetric surveying have been laid one after another in China’s Jiangsu, Shandong, Anhui, Beijing, Tianjin, Tangshan and Yunnan provinces, Gravity monitoring network. The basic calculation element of gravity net adjustment is changed from the previous single segment difference into absolute gravity observation and segment difference. The resulting series of new technical problems have aroused the interest and concern of gravimetric workers.
