查询词典 Fresnel

That is, movement adds only a fraction of the medium's velocity to the light (predicted by Fresnel in order to make Snell's law work in all frames of reference, consistent with stellar aberration).

三、讨论了微波雷达测量对流层顶高度的原理和方法，介绍了Fresnel散射模型，并通过对比研究实验研究了测量方法的可行性。

For single vug,when the lateral scale of vug is smaller than Fresnel radius,and the vertical scale is smaller than tuning thickness,the reflection amplitude of vug is proportional to its scale. For carbonate reservoir with random arranged vug,seismic wave amplitude is proportional to vug density.Key words random medium;forward modeling;carbonate;vug
