The light propagation characteristics and light spot converter principles inside a cone are studied based on the principle of total reflection of light.

提出了一种圆周型光斑模式转换器——透明玻璃圆锥体，根据光的全反射原理论证了光在该圆锥体中的传输规律和对光束光斑模式的转换原理。

About 4,000 light-years from planet Earth toward the nautical constellation Puppis, the nebula spans over a light-year and is energized by ultraviolet light from the central star.

这个星云位在航海星座的船尾座内，离地球约有四千光年远，大小略高於一光年，在中心星紫外辐射的激发下发光。

A novel catalytic resonance light scattering method for the determination of traces of formaldehyde in blood plasma was developed. It was based on the fact that potassium bromate reacted with pyronine Y to form association nanoparticles which gave stronger resonance light scattering effect, and formaldehyde can catalyze potassium bromate oxidizing pyronine Y resulting in decreasing of the intensity of resonance light scattering in sulfuric acid.

在稀硫酸介质中，溴酸钾与吡啰红Y能聚集成较大粒径的纳米微粒而使共振光散射增强，而甲醛能催化溴酸钾氧化吡啰红Y而导致体系共振光散射减弱，据此建立了一种灵敏、简单、快速测定血浆中痕量甲醛的新方法。

Industry that, even though it might be to enable HP notebook CULV original characteristics of the demands of the light completely disappeared, but still a good delaying tactic, mainly due to HP's thin-and-light notebook CULV must be quarter of 2009, Section 4 will be released into the market, Acer CULV notebook is expected to debut in the near future attack will take the lead in market share, HP in this window to launch the product is expected to not only alleviate the Acer notebook CULV possible impact, but also as part of its real thin and light notebook before launching CULV product of the transition.

业者认为，尽管惠普此举恐将让CULV笔记本原本诉求的轻薄化特色全然消失，但仍不失为一好的缓兵之计，主要在于惠普轻薄型CULV笔记本必须待2009年第4季才会推出市场，宏碁CULV笔记本预计在近期便将率先登场抢攻市占率，惠普在此空窗期推出此产品，不仅可望舒缓宏碁CULV笔记本可能带来的冲击，更可作为其真正轻薄型CULV笔记本推出前的过渡产品。

B The necessity of such light is evident from what has been said, for faith is essentially an act of assent, and just as assent to a series of deductive or inductive reasonings, or to intuition of first principles, would be impossible without the light of reason, so, too assent to a supernatural truth would be inconceivable without a supernatural strengthening of the natural light Quid est enim fides nisi credere quod non vides?

"有必要的，例如轻是显而易见的，从已经表示，为信仰本质上是一个法的赞同，正如核可了一系列的演绎或归纳reasonings ，或以直觉的第一原则，将不可能无轻的原因，所以，也赞同一个超自然的真理，就不能想象没有一个超自然加强对自然光"的回报预测单一目的的NiSi credere和非

Now, if light from the rear of the bike has further to travel to you than light from the front., then the light arriving at a particular point in time from each end must have started out at different times-when the bike was in different positions.

现在，如果光从自行车尾到你的距离比从车头到你的距离远，那么从两头发出的光同时达到某一点时，它们肯定是在不同的时刻发出的-当自行车在不同的位置。

本着以"诚信务实"为经营理念，为客户提供高品质的产品和优质的服务。

Modern Chinese artists from China's stage arts, folk art and modern Western painting and drawing useful, a point-kwong, presented by the color tone sandhi a level, the changes in light, to break through the traditional flat light, and that this light A screen Smart lively language.

现代中国画家从我国舞台美术、民间美术和西方现代主义绘画中吸取有益的因素，采用点光、色彩变调所呈现的有层次、有变化的光，来突破传统的平面光，并使这种光成为画面灵动活泼的语言。

The basic light setup consists of a main spot light (better if it's not much coloured) and a back omni light. Place a few omni lights for the glowing parts here and there. I didn't involve any global illumination, just a plain scanline render because another pass of ambient occlusion will be involved later.

基本的灯光设置包括一个主聚光灯（如果它不包含那么丰富的色彩，那就更好）和一盏背光灯，对于有光晕的地方放置一些omni，我没有加入全局照明，只是一个简单的扫描线渲染，因为另外的ambient occlusion渲染层会在晚些时候被包括进来。

Take consider of the comparison of the light efficiency and the color rendering index we can find that: one piece of 1000W plasma lamp can equivalence to 2 pieces of 1000W metal halide lamp( no considering the light declining in ceramics metal halide lamp running ), and the lifetime of plasma lamp is 2 times to the metal halide lamp, so as a total by considering the lifetime and light efficiency indexes the one shot cost of metal halide is : 2×6500×2=26000YRMB, So we can find that the plasma lamp can save us 20500YRMB in the one shot cost.

根据两款灯发光效率和显色性的工程照明指标相比较得出：1个1000W的等离子灯相当与2个1000W金卤灯的照明效果（不计陶瓷金卤灯的后期光衰），而等离子灯的寿命是金卤灯的2倍，综合寿命和照明效果两项指标，在一次性投入上，金卤灯是2×6500×2=2.6 万元，由此可见，等离子灯的一次性投入比金卤灯节省2.05 万元。

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。
