The relation between the characteristic excitation band and the emission band is interpreted with the simple configuration coordinate curve model.

Pankove和Hutchby[2 ] 分别测量了35种元素作为注入杂质的GaN的光致发光谱，他们发现其中大多数杂质的发射峰在2 。1 5eV左右，即黄带

The absorption peak and PL emission peak of PPV-PQ in the solid state, were shift to long wavelengths compared to their corresponding peaks in solution due to strong inter-chain interactions and increased coplanarity.

结果显示，由于在固态下存在较强的分子间作用，分子链的共平面性增加，所以PPV-PQ无论是紫外-可见吸收，还是荧光发射光谱，在固态薄膜下都比在氯仿溶液里发生明显红移。

Energy consumption and environmental emission are evaluated for a 5000t/a cornstalk pellet fuel plant.

以5000t/a的秸秆成型燃料生产厂为例，评价了其生命周期能耗和环境排放。

In 1871, not only emission lines but also absorption lines were detected in the coronal spectrum.

在1871年，在日冕光谱中不仅有射线而且还有吸收线被发现。

At the eclipses of 1868 and 1869, observed from Siam and from the United States, respectively, the first coronal emission line was detected: about 25 years later, it was said to be from the element 'coronium', by analogy with the prior discovery of helium.

1868-1869的一次日蚀期间，观测者由泰国和美国分别观测，第一个日冕射线被检测到，大约25年后，被证实来自元素"coronium"，于氦的发现类似。

So, we make the selective emission through the one step diffusion method by the countercheck effect instead of by the ordinary two step diffusion method.

因此，我们认为可以通过利用SiO_2的阻挡作用，结合机械刻槽和丝网印刷，通过一次扩散宋代替通常的分两次进行扩散宋制作"选择性发射极"的方法。

Based on the data from Eurostat New Cronos database about the GDP, energy consumption and emission of greenhouse gases of European Union in 2003, we explore the relationship between three aspects of social-economy activities. Summary description and regression analysis are adopted in this research under SAS.

基于Eurostat New Cronos数据库提供的欧盟25个国家2003年的GDP、能源消耗与温室气体排放数据，在SAS系统下，运用描述性分析与回归分析，检测了欧盟25个国家经济发展、能源消耗与温室气体排放之间的相关性。

"Aah!" It was not a spoken word, but an emission of breath from the Duke of Croydon.

"噢！"这声音不像是从口中说出来的，倒像是从克罗伊敦公爵鼻子中呼出来的。

The use of the web to spread fears that flicking the switch on the LHC could create a Black Hole that could swallow up the Earth particularly concerned him, he said.
