摘　　要：随着阔叶木在制浆造纸工业中的广泛应用,阔叶木中的导管组分会在纸张印刷过程中产生导管黏出现象。本文介绍了阔叶木导管的结构和特点,探讨了含阔叶木浆纸张印刷过程中导管黏出的机理,并分析了导管黏出的原因,从原料、打浆、酶处理、湿部化学、施胶、印刷等方面给出了减少导管黏出的方案。The increasing use of fast growing tropical hardwoods has led to a significant tendency of vessel picking in offset printing. The properties of the hardwood vessel elements were introduced. The mechanism and fundamentals of the vessel picking were discussed. The so- lutions to vessel picking were presented, including raw material selection, refining, fractionation by hydrocyclone, surface sizing and enzyme treatment methods.
