紫外线

With too much exposure to UV light, your skin overheats and becomes red and painful, and may later peel or blister.

过多暴露于紫外线光，你的皮肤过热而成为红色和痛苦，以及稍后可能会剥离或生殖器疱疹。

To culture antibiotic overproducing strains, the study include using different physical and chemical factors to induce Streptomyces thermocarbonxydus var shandaensis to mutation. After original strain were mutagensised by UV combined LiCl、~(60)Co、 DES, 9 high-yield strains were obtained.

通过紫外线加氯化锂复合诱变得到高产菌株UV—18、UV—19、UV—20，其中菌株UV—19的发酵上清液抑菌圈直径是原种的1.875倍；通过~(60)Co诱变得到高产菌株Co—22、Co—36、Co—38，其中菌株Co—38的发酵上清液抑菌圈直径是原种的1.68倍；通过硫酸二乙酯诱变得到高产菌株DES—21、DES—31、DES—37，其中菌株DES—21的发酵上清液是原种的1.52倍。

Guanosine overproducing mutant was derived from Bacillus subtilis T1001 by using ultraviolet and diethyl sulfate. The mutant was selected directionally and step wisely on the agar plates containing methionine sulfoxide and 8 azaguanine(8 AG).

以枯草芽孢杆菌T1 0 0 1为出发菌株，经紫外线、硫酸二乙酯逐级诱变处理，选育出腺嘌呤缺陷型菌株，然后经蛋氨酸亚砜、8 氮鸟嘌呤( 8 AG)结构类似物平板定向筛选，获得鸟苷高产菌株TA2 0 8。

It quickly pivoted to bring its ultraviolet/optical and X-ray telescopes to observe the burst location.

它迅速地相像使其紫外线/光学和X射线望远镜观察爆裂位置。

This procedure precipitates proteins and hydrophobic peptides that interfere with UV measurement.

这种产品在紫外线的干扰下测量的沉淀物蛋白质和疏水性的缩氨酸。

Illuminated by ultraviolet light, a knob coral pulsates with color as if lit from within.

被紫外线照亮后，环菊珊瑚随着似乎从内部发出的光彩而搏动。

Fluorescence occurs when ultraviolet radiation from just outside the visible spectrum is absorbed and re-emitted as visible light,thus increasing the total amount of light refected from a surface.Fluorescent brightening agents are commonly added to paper and boards to make them brighten and whiter and to increase the possible density range that can be achieved when printing on them.

荧光发生时，紫外线辐射从外面可见光谱吸收和再音量为可见光，从而增加总额轻refected从surface.fluorescent增白剂补充常用纸张和议会，使他们 brightenandwhiter，并把可能的密度范围时，才能得到印刷出来。

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。

Wearing sun-protective clothing, which is available online, can make more sense than slathering on sun-block lotion.

穿着防紫外线的衣服比大量涂抹防晒霜来得更有效。这种衣服可以在网上购得。

The fabrics have nice washing fastness after soaped 20 times.

对织物皂洗20次后测试其抗紫外线效果，发现织物具有较好的耐洗性。

KATHERINA. What is your sir, that you send for me?
