同时反射 meaning in English

concurrent reflex
simultaneous reflex

In the attenuated - total - reflection ( atr ) multi - layer structure , light reflectivity can be highly dependent on layer parameters such as the layer thickness and refractive index . a tiny change in these parameters can lead to a large change in the light reflectivity
衰减全反射( atr )结构是光学上一种较为特殊的反射型结构，在一定的条件下，反射光的空间强度和频谱成分都会受到结构参数的影响和控制，同时反射光也携带上了结构本身的信息。
