摘　　要：对ZnCl2溶液在不同外界环境光存在下的激光拉曼光谱的影响进行了探讨。研究表明不同的外界环境光,自然光和室内荧光灯光,都会对拉曼光谱产生干扰效应,存在着特征谱线,倒峰或尖锐正峰。虽干扰表现不同,但都有影响,不能忽略。因此,在进行溶液拉曼光谱检测时,需在暗室或暗罩中进行,以完全隔离外界环境光的影响。The laser Raman spectra influenced by environmental light were studied in the determination of ZnCl2 solution. The environmental light included the natural light from outdoors and the light from indoor fluorescent. The results show that different influences on the laser Raman spectra of ZnCl2 solution can be produced in different environmental light. There were some characteristic spectral lines, minus peaks or sharpened peaks. These influences cannot he ignored. The determinations of laser Raman spectra must be made in darkroom or in the sheathing or mantle etc.
