摘要
利用组合式多功能光栅光谱仪、澳钨灯和吸收池,对遮阳护肤品进行光谱特性分析,对样品的基线和透射谱进行对比,同时配合对样品透过率的分析,可以得到样品的防紫外线性能,从而开发出一个非常受学生欢迎的综合性应用性实验。
The anti - ultraviolet properties of sample sunlight - blocking cosmetiee can be tested by analysing the spectral properties, comparing the baselines and transitivity spectrums and analysing the penetrance with multi- functional raster spectrograph, bromine tungsten light and absorption pond. In this way, a synthetical applied experiment is developed which win be well- received among the students.
