重力计算中的潮汐改正分析

The Adjustment of the Earth Tide in Gravimetry Caculation

详细介绍了重力固体潮汐改正的来源和计算公式,针对潮汐因子的取值进行了分析讨论,同时就海洋负荷潮汐模型对重力潮汐的影响展开阐述并给出简算公式,最后得出,不同等级的重力测量计算采用相应的计算公式,其计算精度为±2×10-8 ms-2。

This paper introduces the origin of the gravity solid tide correction and the formula for the correction in details. we analyze and discusse the evaluation of the tide factor. The ocean loading tide influence on the gravity tide is also discussed and the deduced formula is given. At last it draws the conclusion that different levels of gravity measurement and calculation showld adopt corresponding formula, the calculation precision is ±2×10-8 ms-2 .
