| 摘 要： | 以Nd：YAG的二倍频532 nm激光为激发光源，用激光诱导荧光(LIF)方法对几种不同水体中溶解有机物(DOM)和叶绿素a(Chl-a)的荧光光谱进行了测量和分析;并以水体对532 nm激发光的散射进行了水体浊度特性的研究，给出了散射光强度与浊度的关系曲线;研究结果表明，用此种方法测量水体浊度和污染物浓度可对水体质量进行有效的监测。

| Abstract: | In the experiment a frequency doubled radiation of Nd:YAG laser was used for excitation at 532 nm. The fluorescence spectra of dissolved organic matter (DOM) and chlorophyll a (Chl-a) in several types of water samples with laser-induced fluorescence (LIF) measurements using a 532 nm wavelength excitation source were measured in the laboratory, and the spectral characteristics of DOM and Chl-a were analysed. The characteristics of turbidity were investigated by measuring the amount of scattering light of suspended particles in the water volume. The curve of scattering intensity against corresponding turbidity of SiO_2 is showed. The possibilities of water quality monitoring based upon the fluorescence spectral characteristics of contaminations and the turbidity by means of LIF method. |
