从木材构造、化学组分和水分等因素对木材动态黏弹性的影响及其机理进行了综合评述。从木材构造方面,阐述了树种、应力木,以及木材的心边材、幼龄材与成熟材、纹理方向、早晚材和微纤丝角等对木材动态黏弹性的影响规律;针对木材化学组分,重点归纳了弹性纤维、黏弹性基体以及抽提物对动态黏弹性的影响机制;总结了木材动态黏弹的水分依存性。最后,对木材动态黏弹性的进一步研究提出了建议。 The effects of wood structure, chemical composition and moisture on the dynamic viscoelasticity of wood and its mechanism were reviewed. From the aspect of wood structure, the influence laws of tree species, stress wood, wood heartwood sapwood, young wood and mature wood, texture direction, morning and evening wood and microfibril angle on wood dynamic viscoelasticity are described. For wood chemistry group The mechanism of the influence of elastic fiber, viscoelastic matrix and extractives on dynamic viscoelasticity was summarized. The moisture dependency of dynamic visco-elastic wood was summarized. Finally, the further research on the dynamic viscoelasticity of wood is put forward.
