摘要
在探讨LaCosteG型重力仪气压响应的数学力学模型及模型参数测定方法的基础上,提出了一种实用的气压改正程序。根据北京高崖口基线的实验观测资料,计算了G570仪器的气压响应模型参数,并对灵山基线的观测结果进行了气压改正,基本消除了气压影响,明显提高了观测精度。
In this paper,a mechanical model to account for the atmospheric effect on LaCoste G gravimeters is presented.And a convolution method is used for the atmospheric effect correction. The model parameters for the gravimeter G570 are determined using many times of observations at the Gaoyakou baseline.In the end,the method is applied to the observations at Lingshan baseline,the application shows that the atmospheric effects are removed on the whole and that the observation precision is obviously increased.
