" In addition, refractive index can also be used to 'invisibility', for example, objects with high borosilicate glass materials can also be 'invisible' when moving in glycerol with a refractive index close to its own, " Chu noted.
“此外，折射率也可以用来‘隐形’，比如高硼硅玻璃材料的物体在折射率接近自身的甘油中运动时也可以‘隐形’，”褚指出。

折射率
某种介质的折射率 n 等于光在真空中的速度 c 跟光在介质中的相速度 v 之比：
比如水的折射率是1.33，表示光在真空中的传播速度是在水中传播速度的1.33倍。
历史上，折射率最早出现在折射定律中， n1sinθ1= n2sinθ2, 其中，θ1与θ2分别是光在介质界面上的入射角和折射角，两种介质的折射率分别是n1与n2。

In optics, the refractive index or index of refraction n of a material is a dimensionless number that describes how light propagates through that medium. It is defined as
where c is the speed of light in vacuum and v is the phase velocity of light in the medium. For example, the refractive index of water is 1.333, meaning that light travels 1.333 times faster in a vacuum than it does in water.
