The paint membrane has the best mirror effect , and can effectively resist radiation of ultraviolet , then enhance aging - resist of decorated objects 漆膜具有最佳镜面效果，能有效抵抗紫外线辐射，增强被装饰物抗老化性。
Photochemical smog : smog produced by action of solar radiation , especially of ultraviolet radiation , on exhausts from vehicles and industry 太阳辐射，尤其是紫外线辐射对汽车和工业所排放的废气产生光化作用而形成的烟雾。
The hole in the ozone layer , which protects earth from the sun ' s ultraviolet rays , was first detected nearly 30 years ago 人们是在约30年前发现这个臭氧层空洞的。而臭氧层的作用主要是保护我们不直接受到太阳的紫外线辐射。
Measurement and assessment of personal exposures to incoherent optical radiation - ultraviolet radiation emitted by artifical sources in the workplace 对处于断续光辐射中的人体测量和评定.工作场所中人工源放射的紫外线辐射
During the course of our research in the early 1990s , we searched in vain to find sources of data on actual uv radiation levels at the earth ' s surface 我们在1990年代初期的研究过程中，没找到地球各地紫外线辐射的实测资料。
A great deal is now known about the kinds of damage produced in the dna by ultraviolet radiations , to a lesser extent , by ionizing radiations 目前已经知道很多关于由紫外线辐射以及在较小程度上由电离辐射引起dna损伤的种类。
3 . the surface of reactor is covered by silicon organic lacquer which will resist ultraviolet radia - tion , so the reactor can be operate in all weather 3 .电抗器表面覆盖有耐紫外线辐射的硅有机漆，具有良好的耐户外气候条件性能。
