According to the H NMRstudy, it was found that the protons on the cyclopentadienyl ring of 〓 were not splitted, but when one proton on the cyclopentadienylring was substituted by methyl, that is in〓 complexes, thefour protons on the ring were splitted into four groups,the 〓 between the onesignal and the others is large, the total splitting is over 2ppm. The splittings werealso affected by the halides linked with the titanium, they increase according to theorder of CI, Br, I. By the study of the 〓 Sn NMR, it is found that the chemicalshifts of 〓 are present in low field. It is assume that the large space strain causesthe angles of the tin linked with ligands deviate from the normal tetrahedral anglesresults low field shift for 〓Sn. And by MS study,there were no molecular ions for 〓 complexes in the spectra. However, for 〓 when X=CI,Br,NCO and Ar is tolyl or phenyl group,there were molecular ions,but theirabundances were very small,and no that for the iodide was found.
钛上的卤素对茂环氢的裂分也有影响,依〓,Br,I顺序,卤素对茂环氢的裂分依次加大;通过对〓的研究发现,以上这些化合物〓的化学位移都出现在低场,认为大的空间张力造成的锡的键角偏离正常的锡的四面体键角是造成〓化学位移出现在低场的原因;对这些化合物质谱的研究发现,〓系列化合物得不到分子离子峰,而〓系列的化合物,当X=〓,NCO和苯环上不带取代基或只带甲基时,则出现分子离子峰,但丰度很低,而相应的碘化物和其它化合物则没出现分子离子峰。

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。

①The collected clinical Acinetobacter baumannii isolates were more seriously resistable to Ciprofloxacin than to Imipenem;②The antibiotic resistance of clinical Acinetobacter baumannii isolates may be associated with the decline of CarO protein expression;③There is some relationship between CarO protein and ciprofloxacin-resistant Acinetobacter baumannii strains,it proves that CarO protein supports bacteria on multi-drug resistance;④CarO protein may be related to cell signalling;⑤The difference in CarO protein functional sites and structure between the sensitive strains and the resistant strains may be related to bacterial resistance.
①收集的临床鲍曼不动杆菌对环丙沙星的耐药情况较亚胺培南严重;②CarO蛋白的表达下调可能与临床鲍曼不动杆菌的耐药性相关;③CarO蛋白与鲍曼不动杆菌耐环丙沙星有一定相关性,佐证了CarO蛋白可能与细菌多重耐药有关;④CarO蛋白可能与细胞信号传导有关;⑤敏感菌株与耐药菌株的CarO蛋白功能位点和内部结构有差异,可能与细菌耐药有关。

In rat esophagus, the positive varicosities and fibres could be observed in the circular muscle layer and the muscularis mucosae layer at 21st day before birth. With the development of rat digestive tract, neurokinin A-immunoreactivity positive nerves could be observed gradually in the epithelium, submucosa, longitudinal muscle layer, myenteric plexus and submucosal plexes, while mature nerve fibres could be seen at one month after birth. 2. In rat stomach, the positive reaction of NKA initially happened in the myenteric plexus at the 14th day of embryo, and then appeared on circular muscles, longitudinal muscles, submucosal, muscularis mucosae, lamina propria and epithelium. 30 days after birth, expression of NKA is same as seen in adaulthood. 3. In rat small intestinal, the NKA-IR could first be found in the myenteric plexus of the duodenum, jejunum and ileum at 14th , 15th and 17th day before birth respectively. Then the NKA-IR occurred in the longitudinal muscle layer, circular muscle layer, intestinal villus, intestinal gland, muscularis mucosae, submucosa, submucosal plexes, mucosa plexus and deep muscular plexus.

When you cut down a tree and look at the stump, you can see that the wood has lots of dark rings in it. Long ago, the wood dried out and people kept throwing darts at the stump, the wood started to crack from the center to the sides. That is why modern dartboards have rings and lines.
