| 摘 要： | 试验研究了红松木材在纵向压应力屈服条件下微观结构的变化。结果表明：与素材相比，屈服条件下试样的自由基浓度显著增加，碳含量相对减少，氧含量相对增加；由压应力产生的机械自由基主要来源于纤维素主键Ｃ－Ｏ键的断裂。

| Abstract: | The change of microstructure of Korean pine (Pinus koraiensis) was studiedby means of the longitudinal compression stress under the yield condition. Theresults show that. as compared with the control wood, the concentrations of freeradical of sample wood under the yield condition increase significantly. the carboncontents decrease and the oxygen contents increase relatively. The free radical produced by the compression was derived from the break of C-O linkage whichis main linkage of cellulose of wood. |
