摘要
地球自由振荡是一种十分重要的地球动力学现象,用重力技术检测地球自由振荡,结合地震技术可为获得地球内部精细结构提供一种重要手段.本文概要综述了地球自由振荡理论研究的发展和重力技术检测现状,详细讨论了利用我国武汉超导重力仪检测到的地球自由振荡本征周期和谱峰分裂现象,结合我国实际情况提出了研究展望,旨在给出需解决的学科问题和相应的策略探讨.
Earth＇s Free oscillations are the very important geodynamical phenomena, the detection of the Earth＇s Free oscillations using gravity technique, and combination of the seismological technique, it provide us with an important measure for obtaining the detail Earth＇s interior structures. The present status on the progress of the theoretical study and detection using gravity technique of the Earth＇s Free oscillations are summarized briefly in this paper. The eigenperiods of the Earth＇s Free oscillations and the frequency spectral splitting phenomena detected using Wuhan superconducting gravimeter in China are discussed in details. Combining with the our real condition in China, the research prospects are given in order to point out the scientific subjects to be solved necessary and the corresponding politic approach.
