摘要
分析对比了各国、各国际组织的标准、准则、手册,澄清了紫外线领域内一些意义模糊的概念,阐述了描述紫外线辐射场的新专业术语"剂量率"和"辐射照度",并讨论了传统的"辐射强度"概念的不严谨性。对UVDIS这一术语所代表的紫外线计算方法进行了深入调查,澄清了在紫外线辐射剂量计算方面的一些误区。在紫外线辐射剂量分布的表达上,指出了现有方法在数学上的不合理性,提出了紫外线辐射剂量分布用概率密度进行表达的方法。
The standards,guidance,manuals from various countries and international organizations were analyzed to clarify the ambiguousness of some key conceptions in the field of UV.The new terminologies of"fluence rate"and"irradiance"were introduced,by which the UV radiation field was depicted.The scientific defect of conventional terminology of"UV intensity"was discussed.Terminology UVDIS,which represents a specific UV calculation method,was deeply investigated.Some misunderstandings/errors in the calculation process of UV dose were clarified.The illustration of UV dose distribution used currently in literatures was pointed out to be unreasonable,and the rational one,which brings in the conception of probability density,was proposed.
