摘　　要：以欧洲山杨为研究对象,研究其经过热处理后的木材力学性能变化,并与黑龙江紫椴的材性进行比较,探索欧洲山杨代替椴木做木制铅笔杆材的可行性。实验表明,经热处理后的杨木板的弹性模量、硬度和冲击韧性都有明显变化,其中冲击韧性的降低非常显著。With Populus tremula as the research object, the change in the mechanical property of wood after heat treatment is studied and compared with the wood properties of Heilongjiang Tilia Amurensis to explores the feasibility of substituting Populus tremula for basswood to make wooden pencils. The experiments show that after heat treatment, the elastic modulus, hardness and impact toughness of Populus tremula have changed obviously, with impact toughness droppng noticeably.
