摘要
木材经机械加工成木屑时,木屑表面的高聚物分子共价键断裂而产生自由基。本研究用电子自旋共振波谱仪观察福建21种常见树种木屑的自由基强度,与树种、材性关系,并就其自由基的类别和稳定性进行分析。
When the wood was made by the machine to wood powder, it will induce free radical formation due to molecular ractare of their chemical components. This studies deal with some results of ESR investigation of free radical formation of 21 major tree species in Fujian. Attempts are made for the i-dentification of these tree species radicals and their stability and the relation between intensity and tree.
