摘要
使用太阳直射光谱系统,记录太阳直射紫外光谱;并透过伞面材料,记录相应的紫外光谱;通过计算得到伞面材料相应波长的紫外UVA透过率,建立紫外UVA透过率谱;比较平均UVA透射比,分析过滤紫外UVA的能力。伞过滤紫外UVA的太阳光谱测试方法具有便于操作的现实意义。
Direct UV spectrum was recorded using direct sun spectral system,and UV spectrum of sunlight through umbrellas was also recorded.UVA transmittance spectrum was obtained by calculating UVA transmittance of the umbrella material.The ability to filter UVA of umbrellas was analyzed by the average UVA transmission.It was great importance to the measurement of sunlight and UVA filter of umbrellas.
