Abstract
The ultraviolet (UV) spectrum is divided into UVC (200-280 nm), UVB (280-320 nm) and UVA (320-400 nm). Of these only UVB and UVA are of environmental significance since UVC is effectively absorbed by ozone in the earth's atmosphere. UVB wavelengths penetrate the epidermis and are almost completely absorbed in the upper dermis while UVA penetrates to the deep dermis.
摘要
紫外线（UV）光谱分为UVC（200 - 280纳米）、UVB（280 - 320纳米）和UVA（320 - 400纳米）。其中只有UVB和UVA具有环境意义，因为UVC在地球大气层中被臭氧有效吸收。UVB波长穿透表皮，几乎完全被真皮上层吸收，而UVA则穿透至真皮深层。
