| 英文摘要 | We utilize random media to describe small-scale inhomogeneity and self-organized structure in the Earth interior. A block model is adopted to describe the self-organized structure instead of traditional grids in 2-D. Gaussian, exponential, and von Karman autocorrelation functions are used to represent the isotropic and anisotropic self-organized structure. We use numerical methods to perform ray tracing and rectify amplitudes by dynamic ray tracing, furthermore, analyze the influence upon the kinematic and dynamic characteristics of seismic waves. The results indicate that seismic ray trajectories probably generate significant aberrances and the amplitudes of seismic rays may weaken or enlarge at different offsets for the existence of the self-organized structure in the earth interior; from Gaussian to von Karman, amplitudes present more obvious statistic characters. |
