摘　　要：采用以DPG为主要成分的药液对印度紫檀（Pterocarpus indicus）、红酸枝木（Dalbergiaoliveri）、鸡翅木（Cassia siamea）和花梨木（Pterocarpus macarocarpus）4种红木进行了处理,分析了不同浓度的药液对处理材ASE和MEE的影响。结果表明,经过药液处理后试件的ASE和MEE随DPG比例的增加而增大,木材尺寸稳定性明显改善,药液中DPG所占比例一般控制在20%~50%之间,综合效果较好。Four kinds of rosewoods, i. e. , Pterocarpus indicus, Dalbergia oliveri , Cassia siamea, and P. macarocarpus, were treated by chemical a solution mainly consisting DPG. Influences of the liquicl on wood properties of ASE and MEE were investigated. The results indicated that with the increased of DPG, the ASE and MEE of the treated samples increased, and the dimensional stability of the timber improved significantly. The general effects were better when the proportion of DPG in the chemical liquid was between 20% and 50%.
