远光

The observer is at a great distance compared to the other dimensions of the experiment and the rays are nearly perpendicular to the reflecting surfaces, then the path difference between the two waves (corresponding to r1-r2 in the preceding section) is just twice the thickness d of the air wedge at each point.

如果观察者比起实验装置来讲距离较远而且光线较接近于垂直反射于表面，那么这两光波的光程差(在前面所述的相应部分 r1-r2)就仅仅是空气劈尖在该点处的厚度 d 的两倍。

The light curve is characterized by a broad peak after periastron, as well as a smaller peak just before apastron.

其光变曲线由一个位于近星点之后的宽峰和一个正好位于远星点之前的小峰组成。

On the beach when we took off his shoes and bare feet of the same towards the coast, far from the sea up the sand and soft tread and Shibuya, where Kennedy was occasionally broken stone and Beja to the feet, through this "deep shallow kick kick "of the beach, came to the coast, from sea water near the beach and the beach is just a different, affected by sea erosion as a result of long-term, so flat like a huge ink paintings of the paper, see both want to get trampled in the above its smooth feel, afraid of their own footprints printed on the above, the destruction of the picture.

在沙滩时我们都不约而同的脱下鞋子光着脚奔向海边，距离海水远的沙子踩上去又软又涩，在那儿偶尔还会被坚石和碎贝扎到脚，走过这段"深一脚浅一脚"的海滩，来到海边，离海水近的沙滩和刚才的沙滩又是有着天壤之别，由于长期受海水冲刷，所以平坦得像一张巨大的画水墨画的宣纸，看上去既想在上面踩几脚感受一下它的平滑，又怕把自己的脚印印在上面，破坏了这天造地设的"画卷"。

I am experiencing this kind of feeling now: Another name for Guangdong Province of Mu of channel of admonish show off is planted the flame that? of armour of Xin Chun Tuo cannot find outlet; to discover far has a very small amount from beginning to end however, running over to look is the wildfire on animal body however there is a few dazzled to glimmering all round; green light, the whoop that accompanying loud and jarring ignore far ignore close... good, too good to avoid you moral nature takes a phone to dial 110, I must admit, I did not search savage in divine clothes tree, never also track Hua Nahu; in Shaanxi town level ground I am to sit before computer merely, cudgel one's brains for, think hard, pray god can save me from inside inspirational and dried up lair come out, good let me write to still calculate pretty good column.

我现在正在经历这种感觉：在黑夜的丛林中往返奔走，却始终找不到出路；发现远处有一星半点的火光，跑过去一看却是动物尸体上的磷火；四周有几点荧荧绿光，伴着粗重的喘息声忽远忽近……好吧，为了避免你过于好心地拿起电话拨110，我不得不承认，我并没有在神衣架寻找野人，也不曾在陕西镇坪追踪华南虎；我仅仅是坐在电脑前，绞尽脑汁、冥思苦想，祈祷上帝能把我从灵感枯竭的泥潭中拯救出来，好让我写完一篇还算不错的专栏。

By using two groups of cylindrical lenses perpendicular to each other, the marking shape window of semiconductor laser is imaged and rectangle and this imagery is then collimate d to infinite by collimating objective.

利用互相垂直的两组圆柱面镜把半导体激光器的条形窗口成像为矩形。再用球面准直物镜组把此象"准直"到"无限远"。该系统把激光器发出的发散光束压缩到在±0.0025弧度内出射光。两组柱面镜的同种倍率互为倒

More than 50 GaAs/GaAlAs High Power Single Quantum Well Semiconductor Lasers are aged. The threshold current decreases during the early aging (first 520 h) and the largest decrease is 57 mA. From the aging result of more than 1000 h at constant current, we find that output power increases during the early aging , and then decay slowly according to exponent law.

通过对50余只808nm的GaAs/GaAlAs高功率单量子阱远结半导体激光器的老化实验观测，在老化初期（前520h），阈值电流随老化时间的延长而下降，下降幅度高达57mA，从1000h多的恒流电老化结果可以看出，器件的输出光功率在老化初期有所上升，随后，表现出按指数规律缓慢下降的行为。

Another 400,000 kilometers away, the Moon's sunlit crescent shines brightly, its night side illuminated by Earthshine.

而在另一边，距离我们大约40万公里远的月球在太阳的照射下闪闪发亮，其夜晚面被地照光照亮。

The tracking precision is got by measuring the far-field facula position of the beacon.

通过测量回馈光远场光斑的位置变化可以得到端机的跟瞄精度。

One system is used for the realtime measurement and record of the laser facula,and another for the realtime measurement and record of the optical intensity.

根据实验的目的和原理，自行研制了两套实验系统：一套为光斑实时测量和记录系统，另一套为光强实时测量和记录系统。运用以上两套实验系统进行了激光远场实验，记录了大量实验数据。

Finally, according to market conditions and market products this article paper analyzes the trends in the development of camera technology, and designs a color night vision camera.

最后根据市场情况和市面上产品的情况分析了摄像机技术的发展趋势，并设计了一款彩色夜视摄像机。

Only person height weeds and the fierce looks stone idles were there.

只有半人深的荒草和龇牙咧嘴的神像。
