Orthochromatic film: Photographic material insensitive to red lihgt but sensitive to green and vlue lights.

Optical Switches and Variable Optical Attenuators are key components in fiber-optic communication systems and Micro-Electro-Mechanical Systems is a promising OSW technology.

光开关和可变光衰减器是光通信系统中的关键器件，而微电子机械系统技术是一种具有发展前景的光开关技术。

Chilling stress induced photoinhibition of PSII and PSI, and active oxygen species might be one of the factors causing the decrease of the oxidizable P700. PSI seemed to be more sensitive to chilling in the low light than P5II.

低温弱光胁迫引起了PSII和PSI的光抑制，而活性氧的积累可能是氧化态P700下降的一个原因，而且PSI对低温弱光比PSII表现得更敏感。

When smooth accelerant is shot by illumination, change smooth energy into electron and cavity above all, next with the oxygen in air (O2) and water element (H2O) reaction, the oxyhydrogen that generates a freeboard oxidation capacity is free base and oxygen anion (O2-).

光触媒被光照射时，把光的能量首先转化成电子和空穴，然后与空气中的氧气(O2)和水分子(H2O)反应，产生具超高氧化能力的氢氧自由基和氧负离子(O2-)。

It is found that thediffraction efficiency of the beam whose projection is antiparallel to the optical axis isdifferent from that of the one whose projection is parallel to the axis inphotorefractive crystals with unidirectional fanning.

发现具有单向光扇的光折变晶体其二波耦合衍射效率沿正负光轴两个方向明显不等。

Bao. I think he does not know the : quasar physics at all!: A simple reason: astronomers detected redshifts of quasars based on the spectr : al lines emitted from the emission line regions, which are 0.1 to 1 parsec (1p : arsec=3.26 light years) far away from the central black hole. Therefore there : is very little effect from the gravitational redshift!

观察到的类星体的光可在几日内有明显的变化，可见类星体的发光区大小在光日尺度以下，即使你认为类星体的光谱线产生于吸积盘，那么吸积盘的大小须在光日尺度以下才能不相矛盾，请你说出一个你认定的类星体吸积盘的大小尺度与该尺度内所具有的质量，及因此计算出的可忽略的引力红移。

A vibration system produces the light path difference in the interference light path and forms the modulation phase difference.

采用了一种与传统迈克尔逊干涉仪不同的干涉光路，通过光在相同传输光路中的顺时针、反时针传输，形成干涉。

Among them are four exclusive options: Daytona Gray, pearl effect; Mugello Blue, pearl effect; Sepang Blue, pearl effect; and Suzuka Gray, metallic.

其中4个专属方法有：代托纳灰，珠光效果；穆杰罗蓝，珠光效果；雪邦蓝，珠光效果；和铃鹿灰色，金属。

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。
