发荧光

After preprocessing video of a fluorescing cocklebur leaf to remove noise and normalize changes in lighting, they identified the patches by looking for segmentations of the data that yielded the optimal division of light and dark regions.

通过预处理发荧光的苍耳属植物叶片后，科学家们通过数据的分割找到了发荧光的部分，并找到光照度最佳的区域。

A second study published in the April 15, 2007 issue of Cancer Research, showed even greater sensitivity with a compound designed to fluoresce while bound to the surface of cancer cells.

另一研究发表在2007年4月15日出版的《癌症研究》，研究发现，发荧光的化合物和肿瘤细胞表面结合时，检测的灵敏度更高。

The results also indicated that the mode of binding of the complex to DNA was intercalation action.

分析结果表明，THP以嵌入方式与DNA发生相互作用，并且生成了不发荧光的络合物。

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。

From the photophysical behaviors of 1, 3, 4-triaryl-2pyrazoline compound (TPP16) at low temperature, it can be considered that the twisted configuration between pyrazoline ring and the non-substituted phenyl group on the position 1 is the fluorescence configuration of conjugated system Ⅰ, and the twisted configuration between pyrazoline ring and P-nitrobenzene group is fluorescence configuration of conjugated system Ⅱ.

研究了1，3，4-三芳基-2-吡唑啉化合物TPP16在低温时的发光情况，发现：在低温77K下，共轭体系Ⅰ(苯基-N1-N2＝C3-苯基)在非极性溶剂中不发荧光，在极性溶剂中有较强荧光发射；而共轭体系Ⅱ(N1-N2＝C3-C4＝对硝基苄叉)在非极性溶剂或极性溶剂中均有荧光发射，表明N1所联取代基与吡唑啉环相扭曲的构象是共轭体系Ⅰ的发光构象，而对硝基苄叉与吡唑啉环相扭曲的构象是共轭体系Ⅱ的发光构象。

Researchers have created a new imaging compound in mice that selectively binds to certain cancer cells and glows, or fluoresces, only when processed by these cells.

研究人员发明了一种可在小鼠中选择性结合被某种癌细胞处理的，可发光或者说发荧光的成像化合物。

"Nocturnal crawler, a scorpion remains well camouflaged under a flash-light's beam, but fluoresces in ultraviolet light , a reaction that remains a mystery to scientists."

夜间爬行者，一只蝎子很会伪装在手电筒的光线，但是发荧光的紫外线，一种反应遗留一种神秘的事物留给科学家。

The split between the two groups can hardly be papered over.

这两个团体间的分歧难以掩饰。

This approach not only encourages a greater number of responses, but minimizes the likelihood of stale groupthink.

这种做法不仅鼓励了更多的反应，而且减少跟风的可能性。
