This phenomenon coincides with Bragg equation and the lawofrefraction.
这一现象与布拉格方程和折射定律所得结果一致。

On the basis of thin-lens focal length measurement experiment, the imaging lawofrefraction-reflection system was further studied.
在薄透镜焦距测定实验的基础上，进一步讨论了折射反射系统成像的规律。

This paper, based on the straight-line transmitting law and refractionlawof light, analysed the conditions that the image of object in water will be clearly observed.
