multiple reflection meaning in Chinese

多次反复
多次反射
多次反育
多重反射

Peaking in the frequency spectrum due to repetition of signals by multiple reflection is not confined to water layers .
多次反射波引起的信号重复在频谱中造成的峰值增多，并不仅仅局限于水层。
The remainder enters the substrate and undergoes scattering and multiple reflections inside the material
余下的光进入底层在介质中经受散射和多次反射。
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 . prestack migration method presented in this paper should be developed to apply in observational teleseismic p waveform data , to study the inhomogeneity of crust and upper mantle
典型的介质模型数值分析表明，与射线方法相比，接收函数的波动方程叠前偏移能对横向非均匀介质准确成像，不仅有较高的分辨率，而且对多次波有较明显的压制作用。
