| 摘 要： | 研究了杉木、马尾松木材管胞零距纵向抗拉强度.结果表明,杉木早材管胞纵向抗拉强度介于310MPa～733MPa,平均499MPa;马尾松早材管胞纵向抗拉强度介于300MPa～590MPa,平均461MPa.两个树种的早材管胞纵向抗拉强度在树高方向(1.3m～7.2m)差异不显著,没有明显的变化规律;含水率对早材管胞纵向抗拉强度的影响不显著,但总体趋势是气干态的强度高于饱水态. |

| Abstract: | The zero-span tensile strength of tracheids of the Chinese-fir and masson-pine were researched.It was shown that the longitudinal tensile strength of early wood tracheids of the Chinese-fir is from 310 to 733 MPa with an average of 499 MPa and tensile strength of masson-pine is from 300 to 590 MPa with an average of 461 MPa;The longitudinal tensile strength of early wood tracheids has no significant variation was observed along tree height from1.3m to7.3m,and no significant variational trend;the effect of m... |
| Keywords: | Chinese-fir masson-pine tracheids zero-span tensile strength |
