摘　　要：对ZnCl_2溶液在不同外界环境光存在下的近红外激光拉曼光谱进行了研究。不同的外界环境光,如自然光和室内荧光灯光,都会对近红外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。建议在进行溶液拉曼光谱检测时,须在暗室或暗罩中进行,以完全隔离外界环境光的影响。The near-infrared Laser Raman Spectra influenced with environmental light had been studied in determination of ZnCl2 solution. The environmental lights included such as natural light from outdoors and light from indoor fluorescent. The results shows the different influences of nearinfrared laser Raman spectra of ZnCl2. There were some characteristic spectral lines, minus peaks or sharpened peaks, which cannot neglect. The experiment when carries on the solution near-infrared Raman spectrum examination,must be carried on in the darkroom or the dark cover or the sheathing or the mantle etc,to completely isolates the external environment light influence.
