内全反射 meaning in English

inner total reflection

But if a substance with a higher index of refraction ? such as skin ? is pressed against the window , the light will be absorbed at the points of contact , a phenomenon called frustrated total internal reflection
但是如果有个折射率比较高的物质（例如皮肤）压住窗口，位于接触点的光就会被吸收，这个现象称为受抑内全反射。
The polarization - dependent diffraction characteristics of the metallic echelle and the total internal reflection ( tir ) types of diffraction gratings are studied , and optimal design method based on the hybrid diffraction method is presented
针对目前衍射光栅器件在损耗、偏振敏感性等方面的不足，本文对金属反射型以及内全反射型凹面光栅的偏振相关的衍射特性进行了矢量分析，并基于混合衍射方法提出了更为准确有效的优化设计方法。
