In reading Kelsen, however, one has to bear in mind that, when he refers to a 'norm', he is usually speaking elliptically: he is uttering a legal proposition which stands for a legal norm, in much the same way that a picture of a dog shows the dog but does not bark.

凯尔森将法律世界分成三层，层层剥茧、步步深入，但我们在阅读凯尔森的著作时必须注意：它言说的对象是不在场的，是隐藏在法律规则背后的，是必须经过思辨才能把握的。

The protein and phospholipid constituent in membrane of neurocyte in brain of chicken with encephalomalacia was separated and studied with the method of SDS-PAGE electrophoresis and the method of high performance-thin layer chromatography respectively The fluidity of neurocyte membrane of chicken with encephalomalacia was determined for the first time The content of Ca and trace elements were determined in chicken encephalomalacia systematically and the status of Fe ion in cerebellum was observed. The activity of enzymes that were relative to metabolism of energy and neuro-medium in brain were checked systematically with the method of enzyme-histochemistry. Pathological examination was carried out by microscopic and ultramicroscopic observation. The apoptosis of neurocyte in brain was checked.

在进行临床观察、定期剖杀并检测体内V〓含量、体重和脑重的基础上，重点研究了与神经损伤有关的以下几个方面的内容：系统地检测了体内自由基代谢和抗氧化系统功能的变化；首次采用SDS-PAGE电泳法分离并检测了雏鸡脑软化症神经细胞膜蛋白组分，并以高效薄层层析法检测神经细胞膜磷脂组分；测定了脑软化症雏鸡神经细胞膜的膜流动性；首次系统检测了脑软化症雏鸡体内钙及微量元素含量，并进行了小脑组织总铁离子状态观察；采用酶组织化学方法系统地观察了脑组织中与脑能量代谢和神经递质有关的酶的活性；对相关组织进行了病理组织学和超微结构观察；并对脑组织中神经细胞的凋亡进行了检测。

It is found that organic nanotubes from keto-enol isomeric dibenzoylmethane with different diameters show unique size dependent properties according to our experimental and calculated results. With the diameters of the nanotubes decreasing, the enol isomers of DBM molecules increased, the intensity of the fluorescence emission enhanced.
