| 摘 要： | 探讨了环境光自然光和室内荧光灯光的存在,对PE透明塑料薄膜的近红外激光拉曼光谱的影响.研究表明不同的环境光,会对近红外拉曼光谱产生不同的明显特征峰.自然光干扰产生的是以倒峰群形式为主,而室内荧光灯光造成的干扰主要以尖锐的脉冲峰形式.虽干扰表现形式不同,但都有严重地影响,在测定时一定要引起重视,不能忽略.建议在进行透明塑料近红外拉曼光谱检测时,须在暗室或暗罩遮光保护中进行,以完全隔离环境光的影响.

| Abstract: | The influence of environmental light on the nearinfrared laser Raman spectra was studied in determination for PE plastics.The environmental lights included natural light from outdoors and light from indoor fluorescent.It shows that the environmental lights have great influences on the measurements of near-infrared laser Raman spectra for PE plastic.The influenced characteristic spectral lines exhibit as down peaks or group of down peaks for natural light,while the sharpened peaks for fluorescence light.The determinations of near-infrared laser Raman spectra of PE plastics were suggested in darkroom or in the dark cover to completely isolate the environment light. |
