The effects of the position and thickness of the low-velocity layer and other parameters on the zigzag dispersion curves of Rayleigh wave are also analyzed. 还深入研究了地表下低速层(LVL)介质的位置、厚度及其他参数对“之”字形频散曲线的相互影响。
Such low velocities are usually seen only near the surface in a zone called the weathered layer or the low-velocity layer. 这样低的速度通常只在地表附近称为风化层或低速层(LVL)的地带中见到。
Profile, the crustal low-velocity layer is identical with the bottom of the seismogenic layer. 剖面上,壳内低速层(LVL)与多震层的底界一致,中地壳很薄的低速层(LVL)与下地壳较厚的低速层(LVL)都具有这一规律。
Whereas the crust on the southern side has a three-layer structure and there is also a low-velocity layer. 南侧地壳为三层结构,同时有低速度层发育。
Low-velocity layer may be important seismogenic structures, and it controled the occurrence of earthquakes. 低速层(LVL)可能是重要的孕震构造,对地震的发生具有控制作用。
