何为紫外线?紫外线是电磁谱中波长从100-400nm辐射的总称,分为长波紫外线(UVA)、中波紫外线(UVB)和短波紫外线(UVC)。紫外线来源有两种,一种是太阳辐射产生的紫外线(最大天然源);另一种是来自人工的紫外光源。
What is UV? UV is the electromagnetic spectrum of wavelengths from 100-400nm radiation collectively, divided into long-wave ultraviolet (UVA), ultraviolet (UVB) and short-wave ultraviolet (UVC). There are two sources of UV light, one is UV radiation (maximum natural source) from the sun and the other is from artificial UV light sources.
