摘　　要：研究了日本落叶松不同无性系不同年轮的单根纤维力学性能。结果表明,不同无性系幼龄材间单根纤维力学性能差异不显著,同株落叶松单根纤维抗拉强度随着年轮的增加而增大,单根纤维弹性模量与断裂伸长率之间存在一定相关性。In this paper,single fiber tensile strength of different Japanese larch clones were studyed.The results showed that there was no significant difference of single fiber mechanical properties among different juvenile Japanese larch clones,single fiber tensile strength increased as annual ring increased in homophytic Japanese larch clones,and there was a correlation between single fiber elastic modulus and elongation.
