摘　　要：以毛竹材为研究对象,探索不同竹龄、竹秆部位、竹壁部位对毛竹材动态黏弹性的影响。结果表明:在相同的测量条件下,随着测试温度的升高,毛竹材的贮存模量逐渐减小,损耗模量先增大后减小。随着竹龄的增加,毛竹材的贮存模量和损耗模量逐渐增大;在竹秆轴向上,毛竹材的贮存模量和损耗模量自下而上逐渐增大;在竹壁径向上。Taking moso bamboo wood as the research object, the effect of different age, bamboo culm and bamboo culm wall on the dynamic viscoelasticity of bamboo wood is explored. The result shows：under the same measurement conditions, with the rise of test temperature, the storage modulus of bamboo wood gradually decreases, with the loss modulus showing a trend of increasing first and then decreasing;with the increase in the bamboo age, the storage modulus and loss modulus of bamboo wood gradually increase ; in the axial direction of the bamboo culm, the storage modulus and loss modulus of bamboo wood gradually increase from bottom to top ; in the radial direction of the bamboo culm wall, the storage modulus and loss modulus of bamboo wood gradually increase from inside to outside.
