The earth free oscillation can be used to constrain structure of the earth interior,including velocity,discontinuity as well as density distribution.
用地球的自由振荡研究地球内部结构、速度间断面、密度分布等具有射线理论不可替代的优点。
Galerkin method is used in this paper to calculate eigen-periods and eigen-functions of free oscillations of different earth models,while boundary conditions are treated with Tau method.
结果表明:在研究地球自由振荡时,Galerkin方法是一种行之有效的方法;随着所采用的地球模型的逐步完善,计算的结果也与观测更加符合。
It is applied to detect the earth\'s free oscillations by NMWT analysis of the observed gravity variations from superconducting,it can recognize and extract the 0S0,which amplitude is only 0.
结果表明标准Morlet小波变换是一个分析自由振荡信号的理想工具。
