| 摘 要： | 利用紫外光谱法和一阶导数光谱法对不同树种及同种树不同产地的阔叶木木屑的浸提分进行了分析。结果表明．不同树种、同树种不同产地阔叶木木屑浸提物的紫外光谱图中。吸收峰的峰数、峰形有一定的差异：一阶导数光谱图中。正、负峰的峰数、峰位、峰形及振幅值的比值差异显著．据此可对阔叶木木屑进行种类的鉴别。

| Abstract: | Extracts of hardwood chips of different kinds,and the same kinds but from different places was investigated by UV spectroscopy.It was found that the UV absorption peaks and spectrum patterns for different extracts show certain differences.In the first derivative spectrum,the number of positive and negative peaks,the peak value and shape,and the amplitude ratio for different extracts show remarkable differences.It is concluded the method could be used to distinguish wood chips. |
