The modified QCM sensors were used to recognize the butylamine isomers in gas. The results showed that the QCM coated with both compounds had preferential affinity to n -butylamine, then i -butylamine, t -butylamine in the range of low concentrations, indicating that in the recognition process, the steric hindrance effect played an important role when forming complex with guest molecules.
修饰的QCM传感器用于识别气相中不同的丁胺异构体,结果发现,在小浓度范围之内上述两种化合物修饰的QCM均优先吸附正丁胺,之后依次为异丁胺和叔丁胺,表明在形成主客体化合物的识别过程中,空间位阻效应是一个重要因素;当分析物浓度增大时,丁胺的极性和磁性成为分子识别的主要因素。

They are:In the third chapter, the crystal structures of these new dca complexes are described anddiscussed in detail. Besides two mononuclear complexes, 1 and 2, complexes 3~15 arecoordination polymer with novel and interesting structural characteristics. 3, 6, 7, 8, 9 are 1Dpolymers, 4 and 5 are of 2D extending structure, while 10, 11, 12, 13, 14, 15, 16, 17 form thefirstly reported series heteronuclear dca coordination polymer, in which (except 10) differentbuilding blocks, with different metal ions in them, construct interesting architecture, like α-and β-type 〓 chains, ladder chain 〓, scaffold structure of 12, and "sandwich"layer structure in 15 and 16, etc..

The analytical results have shown that p ro ducts mainly consisted of some monosubstituted, disubstituted and a few trisub stituted naphthalenes. Except the low activity of HZSM-5 catalyst, all other z eolite catalysts have higher activity. HY and Hβ catalytic activities were the highest, and their naphthalene conversions attained to 79.12 and 55.79 percent respectively, but their selectivities for 2-isopropylnaphthalene, 2,6-diisopropylnaphthalene(2,6-DIPN) and 2,7-diisopropylnaphthalene ( 2,7-DIPN) were too low. ZM catalysts had good activity and much better selecti vity, especially for ZM4-3, of which its 2,6-DIPN/2,7-DIPN ratio was 2.97. Th er efore, some zeolite catalysts are recommended for shape selective isopropylat ion of coal tar naphthalene.
研究结果表明,煤焦油萘异丙基化产物主要由一取代萘、二取代萘以及少量三取代萘组成;除HZSM-5活性较低以外,其它催化剂均有较高的反应活性,其中HY和Hβ反应活性最高,萘转化率分别达75.15%和55.96%,但β位产物的选择性较差;ZM类催化剂既有一定的活性,又有较高的β选择性,是萘择形异丙基化反应理想的备选催化剂。

Compared the similarity and difference of distribution of homologous fragments on X and Y, we suggested that the sex chromosomes of spiny eel have evolved from a pair of homologous ancestral chromosomes, and during the evolution, a pericentric inversion might have occurred on the original Y chromosome, and subsequently terminal regional duplication might have followed, eventually resulting in the differentiation and formation of X and Y chromosomes, then the recombinants between sex chromosomes were repressed, so the sex chromosomes could be inherited steadily.
根据X、Y染色体上同源片段的分布的相似和相异,我们对刺鳅性染色体的分化历程进行了推测,即:刺鳅的性染色体起源于一对原始的同源染色体,通过原Y染色体上的一个明显的臂间倒位,以及染色体末端的异染色质成分的扩增,导致原始Y染色体与X染色体在染色体结构上的分化,从而抑制了X、Y性染色体之间的遗传物质的重组交换,为性染色体的稳定遗传奠定了基础。

As for the ester exchange reaction on phosphorus, it was found that N-phosphoryl histidine the fastest one among all of the N-phosphoryl aminoacids. The results studied by MNDO method indicate that due to theparticipation of imidazole group, the formation of hexa-coordinatephosphorus intermediate made the iso-propoxyl which is opposite toimidazole group more active than the other ones and much easier to leave.When iso-propoxyl left, a new penta-coordinate phosphorus intermediate wasformed, and it is sterically favorable to be attacked by an alcohol from theopposite direction of imidazole.
对于磷上酯交换反应,实验中发现N-磷酰组氨酸反应速度明显高于其它N-磷酰氨基酸,理论研究表明,侧键咪唑基参与下六配位磷中间体形成后,位于咪唑基对面的异丙氧基反应活性大大提高,即从咪唑基的对面位置发生异丙氧基的离去和另一分子醇的进攻,在能量上和空间上都是有利的。N-磷酰丝氨酸的磷上酯交换反应有着类似的特点。
