木材的化学流变学——基础构筑及研究现状

Chemical rheology of wood-basic construct and research review.

为了使国内木材科学界对木材的化学流变学的基础理论及其研究概况有一个比较全面的了解 ,作者在归纳了作为建立木材的化学流变学基础的、关于变形和流动一般理论的基础上 ,就Stein和Tobolsky基于高分子构造变化与应力松弛之间的对应关系 ,关于物理流变学和化学流变学的分类 ,化学流变学研究与其他方法的不同之处 ,Tobolsky等关于不连续应力松弛测定方法等内容做了比较详细系统的介绍 .最后 ,以几个代表性研究为主干内容介绍了有关木材的化学应力松弛。

In order to provide an overall understanding on the basic theory and previous researches of wood chemical rheology, the author discusses some respects on the basis of the common knowledge of deformation and flow, which served as the foundation of wood chemical theology. These respects include the results by Stein and Tobolsky, such as the correlation between the change of polymolecular structure and stress relaxation, the classification of physical theology and chemical rheology, the difference between the research on wood chemical rheology and other methods, as well as a kind of non-continuous method to measure stress relaxation proposed by Tobolsky et al. At last, taking several typical researches as examples, the present research concerning chemical theology such as chemical stress relaxation and chemical creep was introduced.
