光线的

The Law of Reflection states that the angle of reflection of a light ray is equal to the angle of incidence.

反射定律为光线的反射角等於入射角。

"Life and the memory of it cramped,/dim, on a piece of Bristol board"; it can also apply to a source of light to indicate insufficiency

"生活及其回忆在一块上等板纸上束缚着、模糊着"；它也能用于被表示不足光线的来源

生活及其回忆在一块上等板纸上束缚着、模糊着；它也能用于被表示不足光线的来源

The boy focused sun's ray on a piece of wood with a burning glass.

这个男孩用凸透镜使太阳光线的焦点集于一块木头上。

A beam throgh convex lens will be converged, so the lens is also called a converging or positive lens.

凸透镜具有会聚光线的作用，所以也叫"会聚透镜"或"正透镜"。

It can also make the light more diffuse.

这也可以增加光线的漫射。

If a particular color or wavelength of light hits the ytterbium when it is in the excited state this light will be a aplined, generating a carbon copy of the original light. In this way a very lower perfect beam can be amplified many times to produce high power beam that are nearly perfect and are therefore very focusable.

如果一种特殊的颜色或光线的波长击中 Yb ，而此时正是激发状态时，这种特殊颜色的光线将被放大产生高能量的近乎完美而且有聚焦能力的光束。

Wherever there are lights there is a little heat. One gets warm from watching the fat, secure bastards down their grogs, their steaming black Coffees. Where the lights are there are people on the sidewalks, jostling one another, giving off a little animal heat through their dirty underwear and their foul, cursing breaths.

凡有光线的地方总有一点点热气，看着大腹便便、无衣食之忧的王八蛋们喝下一杯杯烈酒和热气腾腾的黑咖啡，一个叫花子也会暖和起来，凡是有光线的地方人行道上总会有人，他们互相推挤，透过脏内衣，通过恶臭的、诅咒谩骂时哈出的气释放出一点儿热量，像牲口一样。

Macroscopically speaking, in order to compensate for the lake of large French windows, it is recommended to replace direct lighting with indirect lighting, and make artificial lighting as close to the softness of natural light as possible.

宏观看之，整体空间建议以间接光来取代直接照明，让人工光线尽量接近自然光线的柔和自然感，以弥补环境中无法拥有大片落地窗的缺憾；微观选择，灯具建议挑选立灯或壁灯来取代吊灯，一般人会误以为立灯占空间，但其实吊灯最容易让空间中的视觉受到阻断，立灯与壁灯由於倚墙而设，不但无此问题，在小区域的光源控制上更具有灵活的弹性选择。

Neither the killing of Mr Zarqawi nor any breakthrough on the political front will stop the insurgency and the fratricidal murders in their tracks.

在对危险的南部地区访问时，他斥责什叶派民兵领导人对中央集权的挑衅行为。

In fact,I've got him on the satellite mobile right now.

实际上 我们已接通卫星可视电话了
