光的

Intensity of light can simply be defined as the amount of light being emitted from a source of light.

光的强度简单的说就是从一个光源发出的光的数量。

As early as 400 BC for many years, China's "Mojing" documented book on the forward line of light, light reflection, as well as the plane mirror, concave mirror, convex imaging phenomenon.

早在公元前四百多年，我国的《墨经》一书就详细记载了光的直线前进、光的反射，以及平面镜、凹面镜、凸面镜的成像现象。

The Supersnake's engine compartment also was detailed using a combination of Meguiar's dressing products, and its engine block was polished to a brilliant concours finish.

超级眼镜蛇的发动机的部件也使用了美光的专用产品，同时，在给发动机进行抛光之后，它呈现了耀眼的光彩。

By adding Polarization Maintaining Fiber on output terminal of SLD and Loyt depolarizer behind polarizer , the Degree of polarity can be reduced to 10 -3 ,and influence of outside conditions to light-wave′ state of polarization can be reduced too.

利用在光源出端加单段保偏光纤和在消偏器后端加Loyt消偏器，可以使进入光纤线圈的光的偏振度降到10-3数量级，降低了因外界因素对线圈中光偏振态的影响而产生的光纤陀螺偏振误差。

Summary: erythritol,an all- natural bull sweeter,offers sensorial as well as functional benefits for use in such food. it can improve taste quality by adding body and mouthfeel,and it is capable of masking unwanted off-flavors often associated with intense sweeteners.

赤藓糖醇是一种清华紫光的官方网天然甜味剂，它可以在功能性食品中使用，它能带来良好的口感，给人清华紫光的官方网的味觉。

Based on MATLAB,this paper explores extraordinary ray 's locus and its features in crystal when uniaxial crystal is turning.

基于MATLAB探讨单轴晶体转动时非常光在晶体内的轨迹及其特征，分析单轴晶体转动一周时非常光的轨迹在晶体内转两圈的条件，利用MATLAB给出这些条件的数值解。

The flash exposure with the Canon - as far as I can see (although I might very well be wrong)- doesn't seem to take into account the exposure settings dialed in for ambient light, but instead measures just the flash exposure at the particular f-stop.

这两张照片对环境光的曝光差了一级。佳能闪灯的曝光—至少我感觉是这样，当然我也可能是错的—没有综合考虑环境光曝光的设置，只考虑了快门速度。

And with decrease in light intensity,the shape of palisade mesophyllchanged from column into invert pyramid.The higher proportion of granum thylakoid,more granum in one ganum thylakoid and lower ratio of chlorophyll a to chlorophyll bwere also the responses of leaves to shading.

在庇荫环境中，栅栏组织薄壁细胞由全光的柱状变成倒锥形、叶绿素a/b率显著降低、叶绿体中基粒类囊体所占的比例提高、每个基粒类囊体垛的片层数量增加等，也是幼树提高叶片对弱光利用能力的主要标志。

It reformed the coventional grazing incidence method of reflecting x ray, and made it possible to reflect x ray in normal incidence way.

它从根本上改变了传统的掠入射反射x光的方法，使正入射反射x光成为可能，并极大的促进了x光学的发展。

It reformed the coventional grazing incidence method of reflecting x ray, and made it possible to reflect x ray in normal incidence way. It moves x ray optics forward greatly.

它从根本上改变了传统的掠入射反射x光的方法，使正入射反射x光成为可能，并极大的促进了x光学的发展。

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。
