摘　　要：红外光谱中干涉条纹与样品吸收峰叠加,严重影响光谱定性、定量分析。本文通过将样品偏转一定角度,消除干涉条纹对光谱谱图质量的影响。该方法简单,不需重新制样。并讨论了干涉条纹峰-峰(谷-谷)间距与倾角大小的关系。Qualitative and quantitative analysis will be seriously affected when samples＇ infrared spectrums are overlayed by interference fringes. A method to eliminate this effect was presented by altering sample inclination angle. It is a much simple way and re-pretreatment is avoided. The relation between sample inclination angle and space between peaks （valleys） of interference fringes was discussed.

关 键 词：干涉条纹 谱图质量 倾角
