为初步判断和估求苏鲁皖和云南地区八个绝对重力点重力值的实测精度和偏差程度,1983年底用10台不同类型的石英弹簧重力仪在这两个地区的几个绝对重力点问进行了联测。综合全部资料分析后认为:(1)中国计量科学研究院所测昆明、保山、连云港、沂水四个绝对点的重力值是可靠的;(2)昆明野毛山、弥渡、徐州、怀远四个绝对点的重力值均存在明显差异,其偏差分别为-110微伽、-200微伽、-30微伽、+50微伽左右;(3)采用多台石英弹簧重力仪进行联测能获得较高精度的重力段差值。
In order to initially judge and estimate the accuracy and deviation of the gravimetric values of the eight absolute gravitation points in Sulu Wan and Yunnan regions, by the end of 1983, using 10 different types of quartz spring gravimeter, several absolute gravity points in these two regions Conducted a joint test. According to the comprehensive analysis of all the data, it is considered that: (1) The gravimetric values of the four absolute points of Kunming, Baoshan, Lianyungang and Yishui measured by China National Institute of Metrology are reliable; (2) Kunming Yomaoshan, Midu, Xuzhou and Huaiyuan IV The absolute values of the gravitational values are significantly different, the deviations were -110 micro-gamma, -200 micro-gamma, -30 micro-gamma, +50 micro-gamma; (3) The use of multiple quartz spring gravimeter joint test Get the higher accuracy of the gravity difference.
