查询词典 longitudinal

To prove our theory, we have done some experiments: 1 observed the focusing and scanning of the longitudinal wave in isotropic solid ; 2 measured the transition process and weighting effect in isotropic solid; 3 observed the focusing of SAW wave on YZ-LiNbO〓 metaled surface and defocusing as deviation from the pure-mode direction.

The numerical results of stationary and transient Green'sfunction for high-velocity surface-head wave on some selected crystals are comparedThrough the above analyse,it is indicate that the first arrival wave mode is thelongitudinal-wave head-wave,and its propagate velocity is equal to the groupvelocity of the longitudinal bulk wave alone the surface.Furthermore,this modedoes not have the Δv/v effect,i.e.,its velocity is the same no matter the surface isfree or metalized.

通过对表面激发的瞬态和稳态Green理论分析和数值计算，表明在压电晶体表面上实际上看到的最高速的最先到达的波动模式是纵波头波，它具有沿表面纵波的群速度，而且对压电晶体，它不具有Δv/v效应，即在自由表面和金属化表面其传播速度是一样的，而压电晶体表面波及伪表面波均存在Δv/v效应。
