紫外线的

ABSTRACT: This assay initially discussed the researches and developments of syntheses and reforming of the tetratlycidyletyer of tetraphenol ethane applying to the copper clad laminate and simply explained its principles and functions of UV-ray shield and fluorescence.

本文对四官能环氧树脂[1，1，2，2—四乙烷四缩水甘油醚]的合成与改性及在覆铜板中的应用作了初步探讨，并对其屏蔽紫外线与产生荧光的机理作用作粗浅的阐述。

A triatomic molecule of oxygen; a natural constituent of the atmosphere, with the highest concentrations in the ozone layer or stratosphere; it is found at a level between 15 and 30 km above the Earth, which prevents harmful ultraviolet B radiation, which causes skin cancer and threatens plant life, from reaching the ground.

中文解释=具有三个氧原子的分子；是大气的天然组成成分，主要集中在臭氧层或同温层中；在地表15~30公里以上的高度，能防止引起皮肤癌和危害植物生长的有害紫外线B辐射线到达地表。

While giving unexpectable moisture to skin, it can fully purify and restore skin cells. It forms a natural plant barrier, which carefully protects skin from ultraviolet radiation, dust and other kinds of radiation, at the same time, relax and revive skin, and help to complete skin restoring process.

在源源为肌肤注入意想不到的水分的同时，更将其净化和修复细胞的特质发挥至淋漓，一层天然植物的屏障，小心呵护表皮肌肤免受紫外线、灰尘和各种辐射，同时舒缓肌肤，帮助完成肌肤自然修复过程。

Since it is not yet mandatory in the US or Canada for manufacturers to rate the UVA protection capabilities of a sunscreen it's up to us to do our homework.

由於现在还不是强制性的在美国或加拿大为制造商率长波紫外线防护能力的防晒霜，它的成立给我们做我们的功课。

One product that disinfects water with UV light is called AquaStar, made by Meridian Design.

其中有一款由meridian design制造的名为Aquastar的机器就是利用的紫外线来对水进行消毒的。

Excellent flex fatigue resistance - Excellent UV resistance The excellent definition of the sections with of the Extrudes thin.

优良的电线使抵抗疲劳-优良的紫外线抵抗用优良的定义挤出瘦的区段。

Indeed it looks like Mars has been cold and dry for billions of years, with an atmosphere so thin, any liquid water on the surface quickly boils away while the sun's ultraviolet radiation scorches the ground.

事实上，看起来像火星一直在寒冷干燥的数十亿年的时间，这样的气氛清淡，任何液态水表面迅速归结距离，而太阳的紫外线辐射scorches地面。

Calcium, blood calcium decreased, the brain caused by increased nerve excitability plant, resulting in baby night waking, night terrors, night irritability, sleep; baby should be given calcium and vitamin D and more sun: A, calcium: elemental calcium daily 200-300mg (1) Composite Calcium Granule: 2-3 packets a day (each contains calcium 100mg)(2) the activity of calcium granules: 4-6 packets per day (calcium per tablet 50mg) B, fill D : daily 400-800IU (1) concentrated cod liver oil drops: 2-4 drops per day (2) vitamin D2 candy: the daily 400-800IU (3) vitamin D3 injections: once a month, 20-300000 IU attention these objects must be a doctor's prescription, prescribed application. C, to the sun to vitamin D, ultraviolet radiation to the skin 7 - dehydrocholesterol into vitamin D3, to help calcium absorption, could be a day outdoors on the sun for half an hour each afternoon. 3, bile is a yellow pigment bilirubin, was it yellow staining and faeces, after bilirubin by oxidation into biliverdin, thus making green manure, the manure discharge encountered in diapers in the air oxygen, so that oxidation of bilirubin biliverdin, so that the surface of green manure.

缺钙、血钙降低，引起大脑植物性神经兴奋性增高，导致孩子夜醒、夜惊、夜间烦躁不安，睡不安稳；应给孩子补钙和维生素D并多晒太阳：A、补钙：每日元素钙200-300mg(1)复合钙冲剂：每日2-3包(每包含钙100mg)(2)活性钙冲剂：每日4-6包(每片含钙50mg)B、补D：每日400-800IU(1)浓缩鱼肝油滴剂：每日2-4滴(2)维生素D2糖丸：每日400-800IU(3)维生素D3针剂：每月一次，20-30万IU注意上述物均须医生处方，遵医嘱应用。C、向太阳要维生素D，紫外线要将皮下7-脱氢胆固醇转变成维生素D3，帮助钙的吸收，可每天户外上下午各晒半小时。3、胆汁中胆红素是一种黄色色素，被它染色及粪便呈黄色，胆红素经氧化过后变为胆绿素，从而使粪便呈绿色，排出的粪便在尿布中遇到空气中的氧，胆红素使氧化成胆绿素，使粪便的表面呈绿色。

Redheads might be more susceptible to skin cancer than brunettes because of differences in the way ultraviolet light affects human pigments.

红色头发的人比深色头发的人更容易得皮肤癌，因为紫外线对不同的人体色素有不同的影响。

Laboratory research has shown that UV radiation from either the sun or tanning devices can cause oncogenic mutations in skin cells, and use of sunbeds has also been associated with increased risk for melanoma and squamous cell carcinoma.

实验室的研究已经显示，无论是来自太阳还是室内晒黑装置的紫外线都能够造成皮肤细胞的突变，并且在晒日光浴也能够增加乳癌、黑色素瘤、鳞状细胞癌的患病几率。

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。
