以莎丽格木材为研究对象,对其解剖特征、密度、干缩率及关键力学性能等材性指标进行测试和分析,并与改良处理前的山杨做了对比,以期为莎丽格木材的应用提供理论依据。实验结果表明,莎丽格木材纤维长度和宽度平均分别为1 284.26、25.91μm,纤维长宽比为50.62,纤维的壁腔比和腔径比分别为0.27、0.67。莎丽格木材基本密度、气干密度和全干密度分别为0.41、0.49、0.46 g/cm3。莎丽格木材弦向、径向、体积的气干干缩系数为0.322%、0.128%、0.476%;弦向、径向、体积的全干干缩系数为0.054%、0.031%、0.385%,气干差异干缩为2.612、全干差异干缩为1.818。莎丽格木材的抗弯强度为72.85 MPa、抗弯弹性模量...

Salicaceae wood was studied as well as its anatomical characteristics,density,shrinkage and key mechanical properties were tested and analyzed,and compared with the unmodified Populus tremula,in order to provide the theoretical basis for the application of Salicaceae wood.The results show that the average fiber length and width of Salicaceae wood are 1 284.26μm and 25.91μm respectively,and the fiber length-to-width ratio is 50.62.The double wall thickness to cavity ratio and cavity to diameter of fiber are 0.27 and 0.67,respectively.The basic...
