摘　　要：利用紫外光照射椴木单板,采用X射线光电子能谱仪(XPS)分析光变色前后碳价态的变化情况。结果表明,C1和C2随着光照时间的增长,呈现出下降的趋势;C3和C4随着光照时间的增长,呈现上升的趋势。Use ultraviolet light to irradiate Veneer, and analyze the carbon valence variation before and after the light discoloration by using X-ray photoelectron spectroscopy （XPS）. The results showed that with the illumination time increased, C1 and C2 showed a downward trend, but C3 and C4 showed an upward trend.
