Reflections from the ground and subsequent refractions by the ozonosphere, cause the usual repeat focus pattern . 地面的反射以及随后臭氧层的折射，会引起那种常见的重复焦点现象。
The light reflected and refracted several times by a droplet and then finally returned to the observer is therefore white . 光由粒子反射和折射数次，最后到达观察者，所以是白色的。
If the light is traveling in the opposite direction, the reverse is true and the ray is bent away from the normal . 如果光线沿着反方向行进，那末就有逆关系成立，即光线更远离法线而折射。
Refraction usually makes it possible to cover a given area in a shorter time and more economically than with the reflection method . 折射法一般能以比反射法更短的时间，较少的费用勘探一个指定的地区。
It may be worthwhile to remark that the refracted and reflected waves are always excited in their totality if the following inequality holds . 但却值得指出，折射波和反射波总是全部被激发的，如果下列不等式成立的话。
The lens telescope, or refractor, was vastly improved when it became possible to manufacture high-quality lenses made from flint glass . 透镜望远镜，或称折射望远镜，在人们能够制造出高质量的火石玻璃透镜以后得到了很大的改进。
Film screen with highly refrected crystal - molecule 薄层屏幕加上高折射度水晶分子
And what questions do the characteristics reflect 这些特点又折射出些什么问题
