摘要：探讨了环境光的存在，对谷氨酸钠溶液的激光拉曼光谱的影响。研究表明，不同的环境光，自然光和室内荧光灯光，会对拉曼光谱产生不同的干扰效应，存在着特征谱峰、负峰或尖锐正峰，干扰的影响不能忽略。建议在进行溶液激光拉曼光谱检测时，需在暗室或暗罩中进行，以完全隔离环境光的影响。

Abstract：The laser Raman spectra influenced by environmental light have been studied in the determination of sodium glutamic acid solution. The environmental light included natural light from outdoors and the light from indoor fluorescents. The results show that different influences on laser Raman spectra of sodium glutamic acid solution can be produced in different environmental light. There were some characteristic spectral lines, minus peaks or sharpened peaks. These influences cannot be ignored. The determinations of laser Raman spectra must be performed in darkroom or in the sheathing or mantle etc.

Key words：Laser Raman spectra;Instrumentation condition;Environmental light;Determination influences;Sodium glutamic acid
