摘　　要：借助于 ESCA(化学分析电子能谱 )研究了某些非木浆 (麦草、芦苇、甘蔗渣、竹子和红麻皮 )中表面木素和抽出物的覆盖情况，并与木浆做了比较。研究发现所有浆料的纤维表面都富集大量的木素和抽出物。在总木素含量相同的条件下，非木浆的表面木素覆盖率要高于针叶木浆。本文分析了这方面可能存在的原因。The surface lignin and extractives coverage of some nonwood pulps (wheat straw,reed,bagasse,bamboo and kenaf bark)were investigated by means of ESCA and compared with wood pulps.Strong enrichment of lignin and extractives on the pulp fiber surface was found for all of the pulps.At the same bulk lignin content level,the surface lignin coverage was found to be higher in the non－ wood pulp than in the softwood pulp.The possible reasons for this were examined.
