摘　　要：利用傅里叶红外光谱仪对棉涤混纺面料进行了衰减全反射实验，采用多元逐步回归法选取了特征波数1000～1400cm^-1来做回归分析，对光谱数据采用中心化和一阶导的预处理方法，建立数学模型，其检测精度达到了较高水平，表明用红外全反射光谱对混纺面料纤维含量的无损测定是行之有效的。In the article, we do attenuation whole reflection to cotton and terylene mixed textile materials by use of FT- IR, adopt stepwisemultiple linear regression to choose characteristic wavenumber 1000 - 1400 cm^-1, spectrum datas are disposed by center change and differential coefficient methods in advance. Math modle is built, the test precision has very high level. So it is effective to test cotton and terylene mixed textile materials by attenuation whole reflection.
