摘要
本文通过分析绝对重力测量点的精度和分布，为我国重力基本网（1985）系统科学地选择了可靠的绝对基准。分析LOR-G型重力仪的特性，采用合理的数据处理方法有助于提高重力基本网的精度。从而建立了点重力值中误差为±5～±13微伽的国家重力基本网（1985）系统。通过外部检核证实了该网的可靠性。

Through an analysis of the accuracy and the distribution of absolute gravity sta-
tions, a reliable absolute datum is selected on a scientific basis for the fundamental gra-
vity standardization net of China 1985. Character analysis of LOR-G type gravimeter
and the adoption of reasonable data processing method help to increase the accuracy,
thereby the national fundamental gravity standardization net with a mean error of ±5-
±13 μgal for a singal station is established. The reliability is also validated by outside
check.
