一束光

It is proven that the choice of entrance of light and the beginning of the tangent from crystal surface has no effect on resolving the final direction of light in crystal by Huygensdiagraph and a conclusion that light will still spread in line in singleaxiscrystal is drawn.

当光波入射至单轴晶体时，由于晶体结构的各向异性，入射光波在晶体中将分成两束，一束称o光或称寻常光，另一束称e光或非寻常光，这种现象被称为双折射。对于o光和

Light holds between its hands The white hill and black oaks, The path that goes o, The tree that stays; Light is a stone that breathes By the sleepwalking river, Light: a girl stretching, A dark bundle dawning; Light shapes the breeze in the curtains, Makes a living body from each hour, Enters the room and slips out, Barefoot, on the edge of a knife; Light is born a woman in a mirror, Naked under diaphanous leaves, Chained by a look, Dissolved in a wink; It touches the fruit and the unbodied, It is a pitcher from which the eye drinks clarities, A flame cut in blossom, a candle watching Where the blackwinged butterfly burns; Light opens the folds of the sheets And the creases of puberty, Glows in the fireplace, its flame becomes shadows That climb the walls, yearning ivy; Light does not absolve or condemn, Is neither just or unjust, Light with impalpable hands raises The buildings of symmetry; Light escapes through a passage of mirrors And returns to light: Is a hand that invents itself, An eye that sees itself in its own inventions.

光 双手拥着白色山峦与黑色橡树林，前行的路，停留的树；光是梦游的河旁呼吸的石光：一个女孩舒展，一束暗色破晓。光勾勒出帘中微风的形状，每时每刻造出一个鲜活的身体，光著脚，踩著刀刃；蹑入房间，又溜走；光是镜中诞生的女人，裸露在透明的叶底，被目光锁定，瞬间消逝；它触摸著果实和无形，眼睛在它的水罐饮著清晰，火焰绽放如花，蜡烛目睹黑翅的蝴蝶燃烧光展开被单的折皱与青春期的皱痕在壁炉里光芒焕发，它的火焰成影在墙上攀爬，怀恋著长春藤光既不赦免也不谴责无公平与不公平而言光，用无法察觉的双手举起对称的建筑；光在镜子的通道里逃遁返回于光：一只发明自己的手，一只在自己的发明中看到自己的眼。

Spearman finally broken in the house, hiding in his military officer in Germany before the playing of Chopin's first Ballade, the bunch of moonlight straight from Spearman shed to the top of the left shoulder, the kind of light symbolizes a kind of sacred; have a bunch of astigmatism in the German officers to fight the front, and this light treatment, this made us think he is like a penitent sinner.

在斯皮尔曼最后藏身的破房子里，在他在德国军官面前弹奏肖邦的第一叙事曲时，一束月光径直的从斯皮尔曼左边的肩膀上方洒下来，那种光象征着一种神圣；还有一束散光打在德国军官的正面，而这种光线的处理，却让我们觉得他像一个正在忏悔的罪人。

Four laser beams as 40K and 87Rb cooling and repump lights are obtained by using acoustic optic modulators to offset the frequencies from the three ECDL lasers. Four light beams with the different frequencies are injected into four slave lasers for injection locking, then Rb cooling light, K cooling light and K repump light are injected into a semiconductor tapered amplifier in a master oscillator-power configuration.

采用三台外腔光栅反馈半导体激光器、四台注入锁定激光器和一台半导体激光放大器组成激光系统，三台外腔光栅反馈半导体激光器通过声光调制器产生四束光，分别作为40K和87Rb原子的冷却光和再抽运光，四束不同频率成份的激光分别注入锁定四台从激光器，然后Rb cooling光、K cooling光和K repump光再同时注入半导体激光放大器进行放大。

The laser diode system is composed of three external cavity diode lasers and four injection diode lasers and a tapered amplifier. Four laser beams as 40K and 87Rb cooling and repump lights are obtained by using acoustic optic modulators to offset the frequencies from the three ECDL lasers. Four light beams with the different frequencies are injected into four slave lasers for injection locking, then Rb cooling light, K cooling light and K repump light are injected into a semiconductor tapered amplifier in a master oscillator-power configuration.

No wonder, then, that such a beam makes all materials vaporise and that it makes possible temperature of millions of degrees.

因此怪不得这样一束光会使所有的材料气化，并能产生几百万度的温度。

Before 9th long life pavilion image of Buddha bunch of light, this time just when noon.

第 9 幅万寿亭佛像前的一束光，此时正值中午。

That is, if has bunch of light to send out by each second 300,000 kilometer speeds from this galaxy, then must pass through in 13,000,000,000 to be able to arrive at the Earth.

也就是说，如果有一束光以每秒30万千米的速度从该星系发出，那么要经过130亿年才能到达地球。

A light slowly, very slowly, comes into the bouncers eyes.

一束光慢慢的，非常慢的进入了Bouncer 的眼睛里。

So if a shuttle lands near you or sends a beam your way folks, use it!

所以如果飞船降落靠近你或向你的发送一束光请赶快进入到飞船内！

We have no common name for a mime of Sophron or Xenarchus and a Socratic Conversation; and we should still be without one even if the imitation in the two instances were in trimeters or elegiacs or some other kind of verse--though it is the way with people to tack on 'poet' to the name of a metre, and talk of elegiac-poets and epic-poets, thinking that they call them poets not by reason of the imitative nature of their work, but indiscriminately by reason of the metre they write in.

索夫农 、森那库斯和苏格拉底式的对话采用的模仿没有一个公共的名称；三音步诗、挽歌体或其他类型的诗的模仿也没有——人们把&诗人&这一名词和格律名称结合到一起，称之为挽歌体诗人或者史诗诗人，他们被称为诗人，似乎只是因为遵守格律写作，而非他们作品的模仿本质。

The relationship between communicative competence and grammar teaching should be that of the ends and the means.

交际能力和语法的关系应该是目标与途径的关系。
