不同于在地球内部传播的体波(P波与S波),在地表传播的面波有着特殊的性质,主要有两种,瑞利波(Rayleigh wave)与勒夫波(Love wave)。Rayleigh wave也有翻译为瑞雷波。 瑞利波是P波与SV波大于临界角入射,由P波与SV波耦合在自由地表形成的波动(这句话对吗?),其质点运动轨迹是垂直于波传播方竖直平面内的逆行(逆时...

A Rayleigh wave and Love wave dual-mode acoustic wave generation device structure and three-dimensional modeling scheme were proposed in order to solve the deficiency that Rayleigh wave and Love wave can not be generated in one acoustic wave device.The finite element analysis method was used in ...
Surface wave data were initially collected from events of magnitude Ms≥5.0 and shallow or moderate focal depth occurred between 1980 and 2002: 713 of them generated Rayleigh waves and 660 Love waves, which were recorded by 13 broadband digital stations in Eurasia and India. Up to 1,525 source...
Related to Rayleigh wave:primary wave,Surface wave n. A type of seismic surface wave that moves with a rolling motion, causing rock particles to vibrate in directions both perpendicular and parallel to the main direction of wave propagation. Rayleigh waves are slower than Love waves. ...

The meaning of RAYLEIGH WAVE is an elastic wave confined to the surface layers of a solid medium; specifically : an elastic wave traveling along the surface of the earth with the plane of vibration coincident with the plane of propagation that is observe
The advantage of Love waves to locate seismic events, however, is mitigated by the fact that Love wave EGFs have a smaller SNR than Rayleigh waves. Here, we test the use of Love and Rayleigh wave EGFs between 5- and 15-sec period to locate seismic events based on the USArray TA in...
