中文摘要: 1985年以来，武汉大地测量国家野外科学观测研究站积累了近35年的高精度重力观测数据；通过广泛的国际合作，建立了亚洲地区唯一的国际重力固体潮基准，建立了台站低频背景噪声模型；构建了全球重力固体潮实验模型和中国大陆精密潮汐改正模型，改善了地表质量负荷重力效应的理论模拟；探测了液态地球的近周日共振、地球自由振荡和地球内核平动振荡等与地球动力学相关的信号，并应用于研究地球深内部物性参数；提出了耦合温度场的球形分层地球的形变理论等。相关研究成果可为国家精密测绘、全球大尺度地球动力学和空间技术提供新的理论指导和背景材料。
Abstract:Since 1985, about 35-year high-precision gravity data have been being well accumulated and worldwide cooperation was effectively carried out. The unique international tidal gravity reference in Asia was established. The background noise model for low frequency in Chinese continent was constructed. A global experimental model and an accurate correction model in Chinese continent for gravity tides of the Earth were both constructed. The theoretical simulation of the effect of surface mass loading on gravity was improved. The signals related to the nearly diurnal resonance, Earth’s free oscillation and translational wobble of the Earth’s inner core were detected to investigate the physical parameters of the Earth’s deep interior. A theory which couples temperature into elastic deformation of a layered and self-gravitating spherical Earth was proposed. The above mentioned achievements would contribute to national precise surveying and mapping, global large-scale geodynamics and space techniques as roles of new instructions and/or references.
