Organic electroluminescence devices were prepared using the new compounds with no electron transporting layer. The capability of electroluminescence was researched and their threshold voltages were between 3-5 V. It can be concluded that these compounds have good electron transporting property while they luminesce.

Based on the layer-optimized method, the devices of sandwiched structure are produced by compounding MEH-PPV and SiO 2 In three different voltage regions of alternating current, the devices luminesce differently.

在分层优化基础上，用MEH PPV和SiO2复合制成夹层结构器件，在交流电压的三个区域下，表现出不同的发光。

With the improvement of luminesce intensity and efficiency of light-emitting diode ( LED), it applications gradually extend to the lighting and display area, and so on.

随着发光二极管（LED）发光强度和发光效率的提高，发光二极管（LED）应用领域逐渐扩展到照明和显示等应用领域。

This gene codes for a green florescent protein that, in nature, makes certain jellyfish luminesce.

事实上，这种基因是一种使得某些水母发冷光的绿色荧光蛋白。

Notably, these organometallic nanosheets luminesce in the red to near infrared region, and their electronic conductivity can be modulated by visible-light irradiation.

尤其是这些有机金属纳米片在红色到计划外区发光，而他们的电子电导率可以用可见光辐照来调整。

Taking advantage of the characteristics of heat luminesce of quartz to prospect for gold deposit and make evaluation

Impatient for such treatments, theseyoungsters are taking the burden upon themselves to carve out a better face.Enter the DIY craze, a potentially hazardous fad among high school friends whoself-apply cheap and scantly regulated tools bought online.

出于对这种手术迫不及待的渴望，这些年轻人自己担负起把脸雕琢得更漂亮的重任，他们加入了DIY狂潮-------在高中学生间流行的、颇具危险的时尚。他们用在网上买的廉价且不正规的工具给自己整形。

Spending Scarlet, like a Woman, Yellow she affords Only scantly and selectly Like a Lover's Words.

自然女神鲜用黄，较之其它色。省下都付与夕阳。——大片泼蓝色，又似女人好鲜红。启用黄色时，千挑万选尤慎重，如爱人措辞。

Because the evaporation is great more than rainfall, and the ground water is deep, soil water is always in the step of wane condition and the soil nutrient are also leanness and available nutrients are scantily, which makes the eco-environment of the plateau very fragile.

由于蒸发潜势远大于降雨量，而地下水埋藏又很深，致使土壤水分经常处于水分亏缺状态，加之水土流失严重，土壤贫瘠，基础肥力低，有效养分缺乏，生态环境十分恶劣。

Among three traditional production factors i.e. capital, labour force and land, the research on the utilization condition and distribution efficiency of land is scantily done in modern economics.

与资本、劳动力相比，作为传统生产三要素之一的土地，其利用状况、配置效率在现代经济学中的研究相对比较缺乏。

Standing is not, after all, physically demanding for most people, and some scientists have questioned whether merely standing up-without also moving about and walking-is sufficiently healthy or if standing merely replaces one type of sedentariness with another.

毕竟，对大多数人来说，站立不是生理需求。有些科学家质疑，只是站立——不动，也不行走——是否足够健康；站立是否只是另一种形式的久坐。

Standing is not, after all, physically demanding for most people, and some scientists have questioned whether merely standing up without also moving about and walking is sufficiently healthy or if standing merely replaces one type of sedentariness with another.

毕竟，对大多数人来说，站立不是生理需求。有些科学家质疑，只是站立不动，也不行走是否足够健康；站立是否只是另一种形式的久坐。

The health consequences of this sedentariness are well-documented.

久坐会带来健康隐患，这一点证据确凿。
