| 摘 要： | 采用平行因子法(PARAFAC法)对太湖水样溶解性有机质(DOM)三维荧光光谱进行解析。通过比较因子数分别为3，4和5时，PARAFAC模型的核一致函数、 激发和发射光谱误差平方和、 各水样模拟的三维荧光光谱和残差谱图等情况，选择因子数为3作为太湖水样DOM三维荧光光谱PARAFAC模型的最佳因子数。太湖水样DOM的3类主要荧光组分分别是类腐殖质荧光物质、 类色氨酸荧光物质、 类酪氨酸荧光物质。 |

| Abstract: | Parallel factor analysis method was used to analyze the three-dimensional fluorescence spectra of dissolved organic matter in the water of Taihu Lake. Based on analysis of the error squared sum of excitation and emission wavelength, the core consistency and the simulation of three dimensional fluorescence spectrum and residual spectrum when the factor of the PARAFAC model is 3, 4 and 5, results show that the best factor number of parallel factor model was three. The three fluorescence components were identified, including humic-like component, tryptophan-like component and tyrosine-like component. |
| Keywords: | Parallel factor analysis Dissolved organic matter Taihu Lake Three-dimensional fluorescence |
