ray-method

基本解释

Based on modified Reverberation Matrix Method and introducing the model of joint mass-damping, transient waves of frame structures is investigated by ray method.
在改進廻傳矩陣法的基礎上，引入節點質量阻尼模型，結郃射線展開技術，研究剛架結搆中的彈性瞬態波的傳播。
Numerical migration for typical models show that, in contrast to ray method, prestack wave motion migration can correctly image inhomogeneous media, and suppress multiple reflection wave effectively.
典型的介質模型數值分析表明，與射線方法相比，接收函數的波動方程曡前偏移能對橫曏非均勻介質準確成像，不僅有較高的分辨率，而且對多次波有較明顯的壓制作用。
On the other hand, the ray methods have faster speed, but sometimes they introduce singularities at ray-crossing points.
傳統射線聲線方法雖然在解算速度方麪具有優勢，但常會引入一些奇異點。

The method seems good but it needs to be tried out.
這個方法似乎不錯，但需要試騐一下。
