| 中文摘要: |
| 在空气介质中对毛竹进行热处理，通过化学成分分析方法探讨了热处理温度（100~220℃）和热处理时间（1~4 h）对毛竹化学成分含量及颜色的影响，并结合热处理后毛竹失重率的变化情况分析了失重率与化学成分变化的相关性。结果表明，随着热处理温度的升高和热处理时间的延长，综纤维素和α-纤维素含量呈逐渐降低的趋势，而酸不溶木素含量呈相对升高的趋势，毛竹的失重率呈逐渐升高的趋势。失重率与综纤维素和α-纤维素含量之间为显著相关，颜色的变化主要由木素颜色的变化引起。 |
| Abstract: |
| In order to study the effect of heat treatment on the chemical composition of bamboo, the Phyllostachys pubescence specimens were treated under temperatures from 100℃ to 220℃ for 1～4 hours in the air. The chemical composition content and color were tested through the chemical analysis method, and the effects of temperature and treatment duration on the chemical compositon content and mass loss were investigated. The results showed that as the temperature and treatment duration increasing, the contents of holocellulose and α-cellulose decreased, but the content of lignin increased relatively. The mass loss rate and the main contents of holocellulose and α-cellulose had significant correlation，the change of the lignin color was the main reason of the bamboo color change. |
