紫外线的

Ultraviolet sunlight can stimulate melanin in the skin, freckles and other skin diseases induced change, the impact of your face, so medical experts will be sunny beauty known as the skin Callisthenics enemy, that women in particular should be careful, even the coldest winter "Ultraviolet" still strong, so applying sunscreen when they go out the best.

阳光中的紫外线可刺激皮肤中的黑色素，诱发雀斑等皮肤病变，影响你的容貌，因此医学美容专家将阳光称为皮肤健美的敌人，强调女性尤其要当心，即使是寒冷的冬天里"紫外线"也依然强烈，所以外出时最好涂抹防晒霜。

This paper introduces the principle and history of Ultraviolet Disinfection Technology and its main functions, such as broad-spectrum sterilization,Effectively killing of giardiasis and Cryptosporidium Hominis, and advanced oxidation process,which respectively solved a difficult problem in water treatment domain, namely By-products of disinfection, threat of Giardiasis and Cryptosporidium Hominis, and refractory biodegradation organic compounds pollution.

本文概述了紫外线消毒技术的原理及发展概况，详细介绍了紫外线技术在水处理领域的三大功效：即广谱杀菌，有效杀灭贾第鞭毛虫和隐孢子虫，以及高级氧化功能，这些功能分别解决了水处理领域的三大难题：消毒副产物问题，贾第鞭毛虫和隐孢子虫的抗氯性问题，以及难降解有机物污染问题。

The UV radiation created is converted to visible light as it passes through a phosphor coating on the surface of the tube.

因为激活的电子从高能态退到低能态，他们放射出紫外线，当通过玻璃管表面的三基色荧光粉时，产生的紫外线转化成可见光。

They signal when your skin type has absorbed a critical amount of U radiation. But Reinhold said it was more important to deelop a feeling for how much sun your skin can take.

当你的皮肤吸收的紫外线量达到临界值的时候它就会发出信号，Reinhold说更重要的是它能使你感觉到皮肤能够吸收多少紫外线。

The principals and features of UV and four chemical disinfection processes were introduced in this paper, and it was pointed out that UV disinfection may become a succedaneum of traditional chemical disinfection methods.

介绍了四种常用的化学消毒法和紫外线消毒法在应用中的原理及特点，指出紫外线消毒法可能取代传统的化学消毒法并且具有广阔的应用前景。

A wide-brimmed hat or cap will block roughly 50 percent of the UV radiation and reduce the UV radiation that may enter your eyes from above or around glasses.

宽边幅帽子将阻挡大约50％的紫外线辐射，减少紫外线辐射从眼镜的上面或周围进入眼睛的可能。

The stabilities of the extract from sanguisorba under different pH, light, heat, ultraviolet ray, oxidant, reducing agent and additive agents were studied. It was indicated the products could widely used in the condition of weak acid or neutral, while they were not stable to heat and light, so they should be used without light and at low temperature. The products had a strong ability to withstand ultraviolet ray. They could easily be oxidized and degraded by oxidant while they were not easily affected by reducing agent and were almost not affected by additive agents. The extract from the stem of sanguisorba was analyzed by UV and FTIR, showing that the structures of the active components were not changed during ultrasonic wave extracting.

研究了pH值、光、热、紫外线、氧化剂、还原剂以及添加剂对地榆提取物稳定性的影响，结果表明地榆提取物适合弱酸或中性条件下使用，使用范围比较广；但对光热稳定性较差，适合在避光低温的环境；具有很强的抗紫外线能力；氧化剂对地榆提取物稳定性影响较大，会加速其降解，还原剂对地榆提取物影响不大；其他添加剂对其稳定性几乎没有影响；并通过UV和FTIR光谱分析，超声波浸提没有对地榆根茎中有效成分的结构发生改变。

Sleever International has developed a new decorative UV-barrier Sleever concept whose transparency is claimed to reveal and enhance the product whilst providing effective protection against ultraviolet light.

Sleever国际已开发出一种新的装饰紫外线阻隔Sleever概念，其透明度是声称揭示和提高产品的同时提供有效的保护，防止紫外线。

Biocontrol may be an alternative to avoid these problems in tobacco disease control. Ata28 strain is an antagonistic bacterium against tobacco brown spot was isolated from healthy tobacco in Chongqing.

Ata28菌株是从重庆烟区烟草健康植株上分离获得的烟草赤星病拮抗细菌，在PDA平板上可明显抑制烟草赤星病强致病力菌株Tbs3的生长，温室控病效果较好；为了进一步提高拮抗细菌Ata28菌株对烟草赤星病的防治效果，本研究采用紫外线、紫外线和氯化锂、硫酸二已酯及微波对Ata28菌株进行诱变选育，以期获得拮抗性能更强，生物学性状更好的优良菌株，为大田使用提供理论依据和实践经验。

The ultraviolet ray shielding ability of common glasses and glasses containing cerium or neodymium at different concentration were compared.

研究了在玻璃中掺杂铈和钕对玻璃的紫外线屏蔽能力的影响，分析了其紫外线吸收的机制。

The split between the two groups can hardly be papered over.

这两个团体间的分歧难以掩饰。

This approach not only encourages a greater number of responses, but minimizes the likelihood of stale groupthink.

这种做法不仅鼓励了更多的反应，而且减少跟风的可能性。
