光反射

One is based on the photoelectricity diffusibility reflection theory. In this method, an expensive photoelectricity sensor is laid closely with the signatures which are lightened by red LEDs. It will be judged by the analog reflection value from the detected area whether the signature is good or not. The other method uses the complex electronic image processing technology to identify some content in the signature.

一是采用光电扩散反射原理，利用特制的光传感器，在和书帖密切接触的情况下，以红色LED作为投光源照射书帖，根据检查区域内的反射光的强弱模拟量大小进行判别；二是使用复杂的电子图像识别技术，针对书帖中部分内容作图像识别。

The transmittance and dispersion relations of one-dimensional photonic crystals containing negative refraction materials were calculated.

利用这一特征可以制造高品质的宽带全方位反射镜，有望在半导体量子阱激光器、共振腔光发射二极管等光电子器中的谐振腔中发挥重要作用。

What? In essence, DLS measures the intensity of light scattered by molecules in solution.

实际上，DLS直接测量的对象是溶液中运动中的众多分子反射的光的强度。

Double refraction and reflection of sequential crystal interfaces with arbitrary orientation of the optic axis are discussed.

3研究了光轴方向任意的单轴晶体的连续双折射双反射。

By focusing on the narrator Ishmael's analogy of human mind as "light" and "color", the main ways of interaction with Nature presented in the novel are incorporated into a whole to reveal the essential truth about Melville's vision of man-nature relationship that Nature is but a meaningless, amoral existence like the Spanish coin the Doubloon on the mast of Pequod, reflecting what the human mind inscribes on it; while human is a spiritual isolato in this colorless, atheistic world.

通过作为麦尔维尔代言人的叙述者伊什梅尔关于人的思想与"光"和"色"之间的类比，文本中隐含的对于自然的几种认识可以合成一个意义整体来揭示麦尔维尔关于人与自然的关系之观念的核心内容，即自然是无意义的，超道德的，就像钉在裴廓德号桅杆上的西班牙金币都布隆一样只会反射出人的思想对它的书写；而人类在这一无意义的无神的世界中只不过是一个精神上的孤独者，只能在人类自身的友谊与亲情之爱中寻找出路。

If there were any inhabitants of the moon, they would see our earth reflecting the light of the sun, again like a huge mirror hung in the sky. They would speak of earthlight just as we speak of moonlight.

假如月亮上有居民，他们也会看到我们反射太阳光的地球同样就像一个巨大的镜子悬在空中，他们也会像我们谈论月光那样谈论地球光。

Still, while the crescent Moonis overexposed, surface features can be seen on the dim lunar nightside illuminated by earthshine - light from sunlit planet Earth.

虽然下弦月的亮区过度曝光，但在地球反照光(被地球向日面所反射的阳光)的照耀下，可以清楚认出暗区的表面特徵。

A novel scheme that improves SOA dynamic performance via increasing properly the facet reflectivity of device is proposed, and is validated in theory by the high-speed dynamic model. Simulation results show evidently that this scheme is superior to other schemes in the efficiency of dynamic characteristic improvement, steady-state gain, output ratio and external condition requirements.

提出了通过适当增加SOA端面反射率来改善SOA动态特性的新方案，并利用SOA高速动态响应模型进行了理论验证，模拟结果证实了该方案改善SOA动态特性的有效性以及在稳态增益、输出信号消光比和对外部泵浦条件的苛刻程度方面相对其他方案的优势。

At first I only know bruck is the idol of American younglings, afterwards I returned back to Taiwan ,even in Beijing last year ,I saw her poster everywhere, I was so surprised at her charm.

起初我只晓得布鲁克雷德丝是美国少男少女崇拜的偶像，后来回台湾，甚至去年在北京，居然也四处看见她的海报，才惊讶她的魅力之大。
