This refraction has a couple of interesting results.

这种射可以导致几个有趣的结果。

Now we're going to talk about refraction of light.

今天我们要讲的是光线的射。

Slowing a wave changes its direction, a process called refraction.

放慢光波了其方向，这个过程被称为射。

Those telescopes that do not employ reflection use refraction.

那些不利用反射的望远镜利用的是射。

Standard stuff - carbon date the cork, run a molecular test on the wax, spectroscopic refraction on the glass.

一些常规程序根据碳含量鉴软木塞年份，给蜡做分子测试，分光镜射来测试玻璃瓶身。

Technically, this changes the index of refraction, but in plain English that means blue light is no longer bent the right way.

从术上讲，这会射率，但用简单来说，这意味着蓝光不再以正确的方式弯曲。

Those telescopes that do not employ reflection use refraction. They have a system of lenses, an idea first used to look at the stars by Galileo.

那些不利用反射的望远镜利用的是射。他们有透镜系统。利用透镜系统的想法最早是伽利略用来观测星星的。

Tomorrow, the 21st, was the day of the equinox; the sun would disappear below the horizon for six months not counting refraction, and after its disappearance the long polar night would begin.

明天21日是春分，析光作用映出的阳光不算，太阳以后就要没水平线下，有六个月不能出来，太阳不见，极圈的长夜时期就开始了。

The key to understanding what that means lies with the term refraction, the ability of a transparent medium, like glass, water, or the eye to change the direction of light passing through it.

理解这代表什么的关键取决于这个术语光能力，一个透明媒体的能力，如玻璃，水，或者眼睛，当光穿过它时，来光的方向。

At 11: 45 the sun, by then seen only by refraction, looked like a golden disk, dispersing its last rays over this deserted continent and down to these seas not yet plowed by the ships of man.

正午差一刻，单从光作用看，太阳像金盘一样现出，它对这从没有迹来过的海面，把它的最后光芒散在荒凉无的大陆上。
