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。

These observations suggest that PVA-MEC is an excellent fluorescent macromolecular material with a convenient method of preparation and had a good water-soluble ability.(2) An acrylic monomer bearing xanthene group, acryloyl-fluorescein was synthesized from fluorescein and acryloyl chloride. The photophysical behaviors of Ac-Flu and its copolymer were explored by recording the fluorescence spectra in solution, solid state and film in detail.

2我们采用基于荧光功能单体制备荧光聚合物的方法，选择荧光素为发色团，使它与丙烯酰氯反应，合成出含有双键的荧光素单体Ac-Flu，然后令其与丙烯酰胺共聚，制备得到含有荧光素生色团的水溶性荧光聚合物poly(Ac-Flu-co-AM)。

Since the molecular clip of glycoluril is also an important supramolecular host but few studies have been done in the field of fluorescent chemosensor,we proceeded with some experiments and research in this field as a trial and designed a series of novel fluorescent chemsensors including different three-dimensional cavities by introducing the fluorophores into the receptor.Their recognition and sensing abilities toward various metal ions and neutral guests were studied.

因此，我们(来源：A1dBC论文网www.abclunwen.com)做了一些尝试性的研究，在传统的甘脲主体化合物上引入荧光发色团，设计了一系列新型的、拥有不同立体空腔的荧光分子夹，并研究了它们对各种金属阳离子以及酚类中性客体分子的识别和荧光传感性能。

The results show that the chlorite jade is in dark green, semi-translucent to opaque, and lepidoblastic texture, with hardness of 2.5, refractive index 1.58 and density 2.60 g/cm^3. It has homogeneous texture and less fissures, and no fluorescence under ultraviolet fluorescence lamp. XRD analysis shows that the mineral composition of the chlorite jade is mainly chlorite.

结果表明，该绿泥石玉呈深绿色、微透明－不透明集合体，具鳞片变晶结构，裂隙少，质地均匀，在紫外荧光灯下不发荧光，摩氏硬度为2.5，折射率为1.58，密度为2.60g/立方公分。X射线衍射分析结果表明，该绿泥石玉的物相为绿泥石。
