摘要
深入认识地球深内部结构和内部动力学问题一直是基础地球科学研究领域的前沿热点,传统方法主要依赖于地震技术。近几十年来,随着新兴的现代重力观测技术革新(尤其是高精度超导重力技术的成功应用),使得检测地球内部动力学现象和物性信息成为可能。本文简述了我国在本领域近年来利用现代高精度重力技术在检测地球自由振荡、自由核章动、内核平动振荡、潮汐模型与极潮和内部结构方面的研究成果进展。
The exploration of deep internal structure and internal dynamics of the earth has always been a hot topic in the field of basic geoscience research.Traditional approach relies mainly on seismic technology.However,in recent decades,the innovation of modern gravity observation technology(especially the successful application of high-precision superconducting gravity technology)makes it possible to detect the earth's internal dynamics and physical information.In this paper,we summarize the research progress of Chinese group in detecting the earth's free oscillation,free core nutation,inner core translational oscillation,tidal model and polar tide and the internal structure by using modern high-precision gravity technology in recent years.
