紫外照度的定义及量值统一

UNIFICATION OF DEFINITIONS AND VALUES IN ULTRAVIOLET IRRADIANCE

紫外照度测量中量值混乱的主要原因是其定义不统一.比较了几种常用的紫外照度定义方法的优劣.在此基础上提出了以紫外辐射产生的辐射效应为基础的统一的紫外照度定义方法.对 A,B,C 3个波段的紫外测量仪器推荐了标准响应函数,其中 A 波段为模拟光化学、光生物学效应等几种典型紫外效应的2个二次函数,B 波段为健康效应的效能函数,C 波段为杀菌效应的效能函数.

The reasons of confusion in ultraviolet irradiance values are studied.It is because the definitions are not unified.The characters of some methods defining ultraviolet irradiance are compared and an unified de- fining method is proposed on the bases of ultraviolet radiant effect.The standard responce functions of the instruments measuring ultraviolet wave- bands A,B,and C are recommended,in which waveband A is two quadratic functions simulating several typical ultraviolet effects in such as photochem- istry and photobiology,and waveband B and C are corresponding to effi- cient functions of healthy effect and sterilizing effect respectively.
