摘　　要：研制了一种能用于红外光谱分析及原位无损检测的恒压光纤式衰减全反射(ATR)探头。基于ATR技术,并配合恒压限位装置,将该探头与样品以恒定正压力接触,可显著提高样品吸收谱的测试可重复性,多次测量偏差小于5%。用该探头分析硝酸酯增塑聚醚(NEPE)推进剂中安定剂的质量分数,测量结果与已有报道相吻合并极大提升了测量的便捷程度。所研制的光纤式ATR探头可广泛用于需对已安装材料进行反复无损检测的场合。A constant pressure fiber attenuated total reflection （ATR） probe which can be used in infrared spectrum analysis and in situ nondestructive testing is developed. Combined with constant pressure inhabiting device, the probe contacts with the sample under constant positive pressure based on ATR technique. It can significantly improve test repeatability of sample absorption spectra, and the multiple measurement error is less than 5~. The probe is used to analyze the stabilizer mass fraction in nitrate ester plasticized polyether （NEPE） propellant. The measurement results are in agreement with previous reports, and it can greatly improve the measurement convenience. The developed probe can be widely used in the occasions where the material has to be carried on nondestructive test repeatedly.
