| 摘 要： | 为了揭示不同处理方法对竹材表面性能的影响规律，该文以毛竹为研究对象，采用ESCA和FTIR分析技术，对不同部位和不同处理条件竹材表面的碳氧比和C1s4种结合形式的分布情况，以及红外光谱的谱峰位置和相对吸收强度进行了分析.结果表明:不同部位和不同处理条件下竹材表面的碳氧比有很大差异；竹材表面主要以木素和各种抽提物为主；高温干燥导致竹材表面易挥发的抽提物分解，使部分纤维素和半纤维素的结构特征得以显露，而硼酸处理效果不明显；高温处理和硼酸处理后竹材表面的自由羟基减少，活性降低；竹黄表面的活性自由羟基的数量高于竹青表面.

| Abstract: | To explore the effects of different treatments on the surface chemical performance,components of Phgllochys heterocyclavar.pubscensewere studied in this paper.The carbon to oxygen ratio(C/Oratio),distribution of C1sinfour combiningforms,andthe positionandrelative absorbingintensityof peaks of Fourier TransformationInfrared Spectroscopy(FTIR)were analyzed by Electron Spectroscopy for Chemical Analysis(ESCA)and FTIRunder various positions and processing conditions of the bamboo surface.Results showedthat:there were significant differences in the carbon to oxygen ratio(C/Oratio)among various positions and processingconditions;lignin and abstracts mainly made up the surface of bamboo;high temperature drying resulted in the decomposition of volatile abstracts in the surface,whichindicated some structure of cellulose and hemicellulose,while the effects of processing with boracic acid were not apparent;the bamboo processed in hightemperature and with boracic acid showed decreasedfree hydroxide and activity at the same time;theamount of active free hydroxide of inner layer was higher thanthat of the outer. |
