我们曾经介绍过一种荧光R显带的方法［10］，在此基础上建立了一种在显带染色体上直接观察杂交信号的新的定位方法：在细胞培养时，同时加入BUdR和Hoechst33258，PI染色后即呈现清晰的荧光R带带型，用彩色和全色黑白胶卷照相均可得到满意的结果，尤其适用于国内具有一般条件的实验室。

A highly sensitive fluorescence quenching method for the determination of iron based on the system of iron-oxfloxacin-SDS has been developed. In NaAc-HAc medium, iron reacts with oxfloxacin and SDS to form a non-fluorescent ternary complex which can quench the fluorescence intensity of oxfloxacin.

在表面活性剂十二烷基硫酸钠存在下，铁能与氧氟沙星形成络合物而猝灭氧氟沙星分子的内源性荧光，使其荧光强度显著降低，据此，提出了铁氧氟沙星SDS体系测定铁的荧光分析新方法。

The fluorescence emission peak of inclusion complex shifted toward short waves and fluorescence intensities decreased in the presence of DNA. The quenching constant was calculated to be 6.12×10~4L mol~(-1) by Stern-Volmer method. The quenching mechanism was studied. The interaction ofβ-CD-TH inclusion complex and thionine with DNA were compared.

荧光光谱实验的结果是DNA对硫堇包合物的荧光峰有蓝移和猝灭效应，猝灭常数Ksv为6.12×10~4L mol~(-1)；探讨了其荧光猝灭机理，比较了硫堇包合物和游离态硫堇与DNA作用程度的大小。

Use a total internal reflection fluorescence microscope to observe, the latter can be sent to filter out the background fluorescence.

这里用全内反射荧光显微镜来进行观察，就可以把后者发出的背景荧光过滤掉。

According to the fluorescence quenching and the fluorescence changing of mixed solution with irradiation time it was indicated that the photo-induced electron transfer between triazine as an electron acceptor and intra-molecular charge tranfer compounds as an electron donor have occurred in these systems.

通过荧光猝灭和体系荧光随时间的变化可看到作为电子受体的三嗪分子和作为电子给体电荷转移化合物间的光诱导电荷转移作用。

Thin leaf section were prepared from fresh tissues of YS-lnfected and healthy citrus plants, when observed under a fluorescence microscope (Type, Olympus AH-FL-2), a yellow fluorescence was distinctly observed in the YS-infected phloem tissues and not in the phloem tissuses of healthy plants and of those infected with tristeza, exocortis, canker, scab, greasy...

将健叶和黄龙病叶叶柄用保险刀片徒手切片，在透射式荧光显微镜下检查，可看到健叶叶柄的木质部导管细胞壁发黄色荧光，韧皮纤维细胞发绿色荧光，而病叶叶柄韧皮部中有1～多个鲜明的黄色或黄绿色荧光团块。这种特异性的荧光，在健叶柄韧皮部中是没有的，其它由病毒、类病毒、细菌、真菌等病原引起的病叶柄韧皮部中亦没有此种特异性荧光。
