The relative integral intensities of the ESCA core electron lines, oxygen and nitrogen to carbon, O18/C18 and N18/C18, are used to indicate the relative degree of grafting of acrylic acid (AA) and acryla-mide (AM) as monomers, respectively.

• 本文对表面接枝纤维用X射线光电子能谱(ESCA)进行分析测试,以谱中氮(或氧)原子1s内壳层电子和碳原子1s内壳层电子谱线的积分强度相对比值来表征接枝程度。
