摘要:
 为了摸清观光木人工林木材的基础材性，对其进行合理的开发和利用，测定和分析了27年生观光木人工林木材的主要物理力学性质。结果表明，观光木人工林木材属轻密度等级材；体积干缩系数属小，差异干缩属中等。抗弯强度、抗弯弹性模量、顺纹抗压强度和冲击韧性分别为79.79、6 517.88、42.38 MPa和26.01 kJ·m-2，对应的强度等级分别为2级、1级、2级和2级；端面、弦面和径面的硬度分别为43.66、30.62 MPa和27.48 MPa，其中端面和弦面硬度均达到了中等硬度水平。木材的综合强度为122.17 MPa，属高强度树种；木材的综合品质系数达到2 929.7×105 Pa，属于高等级材。
Abstract:
 Physical and mechanical properties of the woods collected from a 27-year old Tsoongiodendron odorum plantation were analyzed to provide scientific evidence for the rational development and application of the wood. The results showed that the wood belonged to low density grade wood. The oven-dried volumetric shrinkage coefficient was small, and the difference of oven-dried shrinkage was belonging to middle category. The values of bending strength, modulus of elasticity, compressive strength parallel to grain and impact toughness were 79.79 MPa, 6 517.88 MPa, 42.38 MPa and 26.01 kJ·m-2, respectively. The grade of bending strength, compressive strength parallel to grain and impact toughness were of the second level and modulus of elasticity was of the first level. The values of hardness on cross, tangential and radial surfaces were 43.66 MPa, 30.62 MPa and 27.48 MPa, respectively. The hardness of cross and tangential surfaces were medium. The comprehensive strength was 122.17 MPa, belonging to high strength species. The comprehensive quality coefficient was 2 929.7×105 Pa, belonging to high quality wood.
