光发射

The report of their discovery, which happened by accident, appears in the communication "White-light Emission from Magic-Sized Cadmium Selenide Nanocrystals" published online October 18 by the Journal of the American Chemical Society.

从最新一期出版的《美国化学学会杂志》网络版的"白光从硒化镉纳米晶体中发射出来"的报道可以看出，他们的研究发现也是偶然间得到的。

The Eagle emission nebula, tagged M16, lies about 6500 light years away, spans about 20 light-years, and is visible with binoculars toward the constellation of Serpens.

这幅影像是经过数位合成的彩色影像，原始的影像是三幅透过特殊发射谱线滤光片所拍摄的照片。

Skinhead drive the signal in time will not increase the laser power, so continue to drive long-term life of the severely disadvantaged.

光驱中的光头在读不到信号时就会加大激光发射功率，这样长期下去对光驱的寿命极为不利。

The spectral intensity at every point around needlepoint is obtained by subtracting the sum of emission at outer layer from the sum at inner layer, and the morphology of ionization region is determined.

反应器可上下和左右移动，发射光谱单次测量可得到光纤耦合入口所在直线上的光强之和。

The present invention relates to light diffuser plate, surface emitting light source equipment and liquid crystal display.

本发明涉及光漫射板，表面发射光源设备和液晶显示器。

Light from ordinary stars and galaxies comes largely from atoms powered by thermonuclear reactions in the hearts of stars.

来自一般恒星和星系的光，主要是那些受恒星内部的热核反应所激发的原子发射出的。

Then for the cases when the pumping power is below and above the lasing threshold, the emission intensity, excitation mode and photo distribution are analyzed from theoretical and experimental level.

然后对随机激光泵浦过程中，阈值前后的发射光强、激发模式以及光子数分布，进行了理论及实验上的分析与探讨。

The huge yellow somethings went unnoticed at Goonhilly, they passed over Cape Canaveral without a blip, Woomera and Jodrell Bank looked straight through them – which was a pity because it was exactly the sort of thing they'd been looking for all these years.

这些庞大的黄色物体抵达Goonhilly而完全没有被察觉到，经过卡纳维拉尔角时没有在雷达上留下任何一个光点，Woomera（澳大利亚的火箭发射基地）和Jodrell Bank也对它们视而不见——这真是遗憾，因为这完全就是他们这么多年以来一直在寻找的那种东西。

The HEED, XRD, and XPS results confirmed the forming of intermetallic compounds between silver and rare earth. As far as silver and lanthanum be concerned, the format of intermetallic compound is AgLa.

由此，本文首次提出了稀土元素在稀土金属间化合物中的能量传递模型，认为稀土与银金属间化合物的4f能级位于费米能级附近下方，部分局域化且与导带部分耦合。4f能级与导带能级之间的电子跃迁是稀土元素在Ag-BaO薄膜中传递能量的方式，也是光电发射增强效应的来源，而4f电子的光吸收截面随入射光子能量的增加而增大的特点则是&蓝强&现象的原因。

By comparing the influence of the solvent polarity, in the fluorescence experiment, for PTCP and PPCP, the bathochromic shifts are attributed to the locally excited process.

通过考察溶剂极性对该类D-π-A分子光物理性能(来源：A28BC论a5文网www.abclunwen.com)的影响，发现当共轭体系较小时，PTCP和PPCP发射的是本体荧光，即源于局部激发态LE态。
