The results showed that: three major peaks,humuslike fluorescence peak A,proteinlike fluorescence peaks B and C appeared on the threedimensional fluorescence spectroscopy;the DOM fluorescence intensity was well related with DOC and CODMn,indicating that fluorescence dissolved organic matter content can reflect both the organic carbon content and the organic matter content by oxidation in the water in August,during the nonalgae bloom outbreak period,fluorescence intensity had a poor correlation with chlorophyll a,indicating that phytoplankton was not the main source of the fluorescent substances.

结果显示：小江回水区DOM的三维荧光光谱主要表现出3个峰，类腐殖质荧光峰A、类蛋白荧光峰B和C；DOM荧光强度与DOC、CODMn相关性较好，表明荧光溶解有机物质的含量可以较好反映水体中有机碳和可被氧化有机物的含量；在8月份非水华暴发时期荧光强度和叶绿素a相关性较差，表明DOM荧光物质主要不是由浮游植物产生。

The results show that ponceau 4R excited by light at the wavelength of 330-430 nm can generate a strong fluorescence at the 621 nm peak wavelength with its best excitation wavelength being 376 nm, amaranth excited by light at the wavelength of 300-440 nm can generate a strong fluorescence at the 643 nm peak wavelength with its best excitation wavelength being 370 nm, tartrazine excited by light at the wavelength of 280-380 nm can generate a strong fluorescence at the 565 nm peak wavelength with its best excitation wavelength being 315 nm, sunset yellow excited by light with wavelength of 310-410 nm can generate a strong fluorescence at the 592 nm peak wavelength with its best excitation wavelength being 348 nm, and brilliant blue excited by light at the wavelength of 320-390 nm can generate a strong fluorescence at the 456 nm peak wavelength with its best excitation wavelength being 350 nm.

结果表明，胭脂红在波长330～430 nm的光激发下，产生较强荧光，荧光峰值波长为621 nm，最佳激发波长为376 nm；苋菜红在波长300～440 nm的光激发下，产生较强荧光，荧光峰值波长为643 nm，最佳激发波长为370 nm；柠檬黄在波长280～380 nm的光激发下，产生很强荧光，荧光峰值波长为565 nm，最佳激发波长为315 nm；日落黄在波长310～410 nm的光激发下，产生较强荧光，荧光峰值波长为592 nm，最佳激发波长为348 nm；亮蓝在波长320～390 nm的光激发下，产生较强荧光，荧光峰值波长为456 nm，最佳激发波长为350 nm。

Secondly, we provide a two-level model to depict the one-, two-and three-photon fluorescent process and with it to calculate the one-, two-and three-photon fluorescence intensity dependence of the incident excitation intensity and time. We study the fluorescence intensity when excitation light's time distribution are square pulse、Gaussian pulse and sech pulse. We find that the influence of excitation light's time distribution on the two- and three- photon fluorescence peak intensity is larger than the one-photon fluorescence peak intensity. Two-level model can account for the behavior of saturation fluorescence.

然后用二能级模型解释了单、双、三光子激发原理，在理论上推导出了单、双、三光子吸收诱导荧光强度与脉冲强度以及脉冲作用时间的关系，并进一步研究了入射光时间分布分别为矩形、高斯型、双曲正割型时激发溶解在氯仿溶液中的C22H22N4O样品所产生的荧光峰值光强，结果表明激发光的时间分布对双、三光子荧光峰值强度的影响比对单光子的影响要大。

Fluorescence：荧光

参阅"荧光"(fluorescence)条. 磷光若在撤去激发辐射后的一个易于观察到 的时间间隔里,所吸收的辐射能以比吸收辐射较长 的波长重新发射出来,那么这种发射光叫做磷光. 用 磷光计测定的持续时间一般从约. .001秒到几秒不 等,

Fluorescence：萤光

"萤光"(Fluorescence)是当某些物质受到紫外线能量的激励时所发射的光. 当这种激励移去时,就停止发光. "磷光"(Phosphorescence)是在激励根源移去以后仍然继续发射光线. "杀菌光"(Germicidal)是一个通用的名称,用来描述短波紫外光.

Fluorescence：螢光反應

6.Color Grade颜色等级: 钻石颜色等级与萤光反应(Fluorescence)10.钻石图解:钻石的各种特徵在图上都用符号标示出来,旁边会有符号的注解(Key to Symbols)表示图上的符号所代表的是什麼净度特徵.

Fluorescence：荧光反应

就如同褐色或灰色钻石很难同黄色钻石比较成色高低一样. (二)CZ的火光(色散光)比钻石强,会影响判断成色的准确性. (三)CZ颜色的稳定性不佳,过一段时期后,成色等级自然发生变化. 所以美国宝石学院拒绝鉴定CZ为标准成色钻石. 十一、荧光反应(FLUORESCENCE)

fluorescence spectrum：荧光光谱

采用紫外光谱(uV-spectrum)、荧光光谱(fluorescence spectrum)以及红外光谱(FT-IR spectrum)分析了SAPP以及其MTGase-聚合物的结构特征.紫外光谱结果显示MTGase催化SAPP导致它的多肽链的侧链结构发生了变化,Tyr和Trp残基的吸收峰红移说明其Ca原子的构型从非平面型转变为平面型,
