| 摘 要： | 应用电子自旋共振（ＥＳＲ）波谱仪，在实验的基础上定性或半定量地研究了在电磁辐射、水热条件，氧及臭氧等因子作用下红松试材表面自由基浓度的变化。结果表明，诸因子均能诱发木材表面自由基的形成，导致试材表面材质的劣化；以电磁辐射的紫外光波段对木材化学组分的木素成分的降解产生的自由基为主。

| Abstract: | The authors took Korean pine(Pinus koraiensis Sieb.) as sample wood and studied the change of free-radical concentration of the sample wood sur face by means of these factors:electromagnetic radiation,water,heat,oxyg en and ozone. The results showed that among above factors, the most impo rtant one which degraded the lignin and produced the free-radicals mainly is ultraviolet radiation (UV). |

| Keywords: | Free-radical Ultraviolet radiation Lignin |
