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，毛竹材的贮存模量和损耗模量由内而外逐渐增大。

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.
