| Abstract: | 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 eigen-periods 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. |
