木材的水分吸着和干缩湿胀——从静态到动态的研究

Studies on Moisture Sorption and Hygroexpansion of Wood from Static Condition to Dynamic Condition

较系统地介绍了木材的水分吸着和干缩湿胀从静态到动态研究的发展历程,并归纳了有关恒定温、湿条件和湿度循环条件下及湿度循环过程中3个阶段木材水分吸着和干缩湿胀的研究成果及存在的问题,同时对今后需要研究的课题进行了讨论。旨在帮助木材科学工作者对该领域的研究进行较全面的了解,并希望他们能够从中得到启迪和借鉴,把这方面的研究工作提到一个更新、更高的层次上。

This paper introduced systematically the progress of research on moisture sorption and hygroexpansion of wood from static condition to dynamic condition, and summarized the previous investigations and problems in studying moisture sorption and hygroexpansion of wood under three stages of constant temperature and humidity, cyclic humidity condition and humidity circulating process, respectively. Moreover, some prospects for future study were proposed. The purpose of this paper is to provide an overall understanding about studies in this field, and further to promote the research onto an advance level.
