不发光的

Finally, a two-mask process was attempted to extend the same concept of the chip process. Here the mask of the contact aperture was replaced by the mask of the LED pad. After etching the SiO2 and ITO in the aperture region, a lateral etch of SiO2 was made to increase the ITO contact area. Although the forward voltage of the GaN LED shows a normal value, the process yield is still low and requires further study.

二道光罩制程延伸了三道光制程的理念，只是因为透明导电层的圆孔图形，是用电极的光罩去开的，所以蚀刻完二氧化矽膜及氧化铟锡膜后，必须再做二氧化矽膜的回蚀刻，让二氧化矽再内缩进去，以增加氧化铟锡和电极的接触面积，不会造成发光二极体的顺向电压提高，但因制程良率太低，所以还须要继续研究改善。

Rows of buildings that manage to glitter and molder at the same time. Bright neon over ancient, squalid, sponge-rotted structures. If you don't go at night, you won't go. Because to see these places by daylight is to see the bottom line of our flimsy contract with life.

成排的建筑，在同一刻有的闪闪发光，有的腐朽衰颓，明亮的霓虹灯挂在古老的，肮脏的，衰朽的建筑物上，如果不是晚上，你最好别来，在白天的阳光照射下，看着这些地方，就像看着我们脆弱生命的悲惨结局。

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。

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。

The efforts that have been made to explain optical phenomena by means of the hypothesis of a medium having the same physical character as an elastic solid body led, in the first instance, to the understanding of a concrete example of a medium which can transmit transverse vibration but later to the definite conclusion that there is no aluminiferous medium having the physical character assumed in the hypothesis.

为了解释光学现象，人们曾试图假定有一种具有与弹性固体相同的物理性的介质。这种尝试的结果，最初曾使人们了解到一种能传输横向震动的介质的具体实例，但后来却使人们得出了这样一个明确的结论：不存在任何具有上述假定所认为的那种物理性质的发光介质。

Because of the high optical functions as fluorides and the ease in fabrications and high chemical stability as oxide glasses, oxyfluoride glass ceramics, as an special kinds of materials different from crystals and glasses, became a promising host materials for rare earth ions.

玻璃陶瓷作为一种不同于玻璃和晶体的特殊形态的上转换材料，由于兼具氟化物材料的好的光学性质和氧化物材料的稳定性及易于制作，可加工成各种形态的优点而可能成为一种有优良的上转换发光材料。

Parents support : It is always one in nine years to kiss a teacher and create the era of win-win, only parents invest the selected editions , push , support of the administrative affairs planning , activity , assistance of the teaching scene of course of the teaching material, all educational reforms give out light with move about shinily.

科技支援：以科技视听媒体进行教学及学习，以信息网络深化课程，以影像媒材进行宣导及教学，以信息设备强化行政效率，以监控系统维设校园安全，科技在本校不只是新鲜的工具，更是落实教育的伙伴。5。家长支援：九年一贯是个亲师共创双赢的时代，唯有家长投入教材的选编、课程的推动、行政事务规划、活动的支援、教学现场的协助，所有的教育改革与活动才能发光发亮。

Conjugated polymers which are different from traditional semiconductor, have some unique properties. Most of them are quasi-one-dimensional systems with strong electron-phonon interaction. Their carriers are composite particles, which are different from simply electron and hole, characterized with the surrounding distortion of lattice configuration (polaron with spin 1/ 2 , bipolaron with spin 0 etc.). The transport of the carriers and the process that oppositely charged polarons combine to from exciton are believed to be of fundamental importance for electroluminescence properties.

共轭聚合物具有不同于传统半导体的特性，它们是强电-声相互作用的准一维体系，其载流子不再是简单的电子和空穴，而是伴随晶格畸变的具有内部结构的复合粒子(自旋1/2的极化子、自旋为0的双极化子等)，这些载流子的输运、以及正负极化子对复合成激子的过程在很大程度上决定着聚合物的电致发光性质。

Upon this Occasion of removing my Ammunition, I took occasion to open the Barrel of Powder which I took up out of the Sea, and which had been wet; and I found that the Water had penetrated about three or four Inches into the Powder, on every Side, which caking and growing hard, had preserv'd the inside like a Kernel in a Shell; so that I had near sixty Pound of very good Powder in the Center of the Cask, and this was an agreeable Discovery to me at that Time; so I carry'd all away thither, never keeping above two or three Pound of Powder with me in my Castle, for fear of a Surprize of any kind: I also carry'd thither all the Lead I had Belt for Bullets.

烧木炭的事顺便就谈到这里。再说有一天，我正在那里砍柴，忽然发现，在一片浓密的矮丛林后面，好像有一个深坑。我怀着好奇心想进去看看。我费力地走进洞口，发现里面相当大。我在里面站直了还绰绰有余，甚至还能再站一个人。可是说实在的，我一进去就赶快逃出来，因为我朝地穴深处一看，只见里面一片漆黑，在黑暗中，忽然看见有两只发亮的大眼睛，也不知道是魔鬼的眼睛，还是人的眼睛，在洞口射进去的微弱光线的反射下，那对眼睛像两颗星星闪闪发光。

Chrysanthemum of 10 thousand birthday is lax to edaphic requirement, with the arenaceous qualitative loam with fecund, good drainage had better.

万寿菊对土壤要求不严，以肥沃。排水良好的砂质壤土为好。
