摘　　要：研究不同规格软木材料的吸水性,及加入渗透剂和抽真空-加压两种处理方式,对软木材料吸水率的影响。结果表明:软木材料的吸水率随其体积的增大而减小;渗透剂对提高软木粒子的吸水率有一定作用,而抽真空-加压处理的效果不显著。In this paper, the authors studied the relations between water absorption and size of cork materials （cork particles and cork bulks）, and the effects of chemical treatments and vacuum- pressure on water absorption of cork materials. The results showed smaller sized cork material absorbed more water and the chemical treatment had a considerable effect on their water absorption. It was noticed that vacuum-pressure had no significant effect on water absorption.
