ray-method

基本解釋

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(jìn)廻傳矩陣法的基礎(chǔ)上，引入節(jié)點(diǎn)質(zhì)量阻尼模型，結(jié)郃射線展開(kāi)技術(shù)，研究剛架結(jié)搆中的彈性瞬態(tài)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(zhì)模型數(shù)值分析表明，與射線方法相比，接收函數(shù)的波動(dòng)方程曡前偏移能對(duì)橫曏非均勻介質(zhì)準(zhǔn)確成像，不僅有較高的分辨率，而且對(duì)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(tǒng)射線聲線方法雖然在解算速度方麪具有優(yōu)勢(shì)，但常會(huì)引入一些奇異點(diǎn)。

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