热发光

The bright light, the "meteor", is due to the hot air and hot silicon and other metals in the meteoroid itself glowing from the heat.

流星的亮光是由于热的大气层、热的硅和流星体的其他金属作用下发光产生的。

A novel bis (o-aminobenzophenone) s monomer is synthesized, and is used to get three different polyquinolines containing phenylamine moiety through Frieldlander reaction. The solubilities, thermal stabilities and luminescent properties of the polymers were evaluated. All the polymers are thermal-stable, and are soluble in common organic solvents. The emission of their thin film is from excimer emission.

合成了一种新型的二邻氨基二苯酮单体，通过Frieldlander反应，可以构造出不同结构的含有类三芳胺基元的发光聚喹啉，对其溶解性、热性能进行了研究，结果表明这类聚喹啉在常用有机溶剂中的溶解性有了很大提高，同时保持了聚喹啉较高的热稳定性；研究了它们在溶液态和薄膜态的紫外可见吸收光谱和荧光发射光谱，发现它们在薄膜态下的荧光发射主要来自于分子间激基复合物发射。

I smelt the rich scent of the heating spices; admired the shining kitchen utensils, the polished clock, decked in holly, the silver mugs ranged on a tray ready to be filled with mulled ale for supper; above all, the speckless purity of my particular care - the scoured well-swept floor.

从融化的香料中我问道了浓郁的问道，欣赏着闪闪发光的厨具，擦亮了的钟，节日的装饰，整齐排列在碟子里的银杯子（晚餐的时候会在里面倒满热热的麦酒），尤其是我精心洗擦过的光洁无暇的地板。

SEM, Raman and PL spec trum were adopted to characterize the surface , structure and photoluminescence property of samples. In comparison with those prepared by anodising p type silic on, the porous silicons prepared by non-acid hydrothermal method have smooth su rface , regular shape of pores , and higher PL efficiencey.

实验采用扫描电镜、拉曼光谱和光致发光谱对样品表面形貌、结构及发光性能进行表征，并与用常规电化学阳极氧化法制出的多孔硅进行了对比研究，研究结果表明用无酸水热法制出的多孔硅表面平整，孔的形状规则，发光效能提高更多。

From the results of experiments, the best device of oligomers mixed with PBD as emitting layer : we got electroluminescence of P9 as green-blue; low turn on voltage was 4V; the best brightness was1240 cd/m2, and the best efficiency was 1.69 cd/A .

所得到的寡聚物P127，具有高的热裂解温度（3205800C），及75~2420C的Tg点。寡聚物为发光层加入PBD的基本元件里ITO/PEDOT/Polymer(P1箊27+PBD/ Ca/Mg：P9为蓝绿色发光（478nm），具有低的启动电压4V，其最大亮度为1240cd/m2，最大效率为1.69 cd/A 。

Quasi-1D features in carrier transport, recombination and emission, et al., were studied in the V-grooved QWR samples modified by selective ion-implantation and rapidly thermal annealing, by means of Micro-photoluminescence and magneto-transport measurement.

利用显微光致发光光谱研究经选择性离子注入和快速热退火后的单根GaAs／AlGaAs量子线结构体系中的载流子在输运、复合发光等方面的一维特性。

Ore-bearing and barren rocks and soils were sampled in granite type uranium deposit s, and their glowing curves and intensities were measured.

在花岗岩型铀矿床上分别采集了含矿和无矿岩石样品及含矿和无矿土壤样品，用精密热释光剂量仪测量了它们的发光曲线和发光强度，并对所测结果进行了对比分析。

The resulting luminescent materials were characterized and analyzed by IR,TG and light-decay spectrum. Their properties of water resisting and dispersion were also investigated by using pH and sedimentation test.

采用红外吸收光谱、热失重和荧光光谱等对改性的发光材料进行了表征和性能测试，并通过pH值测定结果和沉降实验对改性的发光材料的耐水性和分散性进行了测定。

Glories like glowworms,a far off shine bright,but looked to near,have neither heat nor light.

荣誉就像萤火虫，远看闪闪发光，但近看既没有热，也不发光。

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。
