The 1s electron cloud in hydrogen atom has the largest probability density distribution around a spherical shell with Bohr radius a 0. The author thinks the probability density distribution and electron cloud belong in fact,to statistic regularity, and imply a macro-time scale is used, therefore in hydrogen molecule the product of energy and time is far larger than Planck Constant.

氢原子中 1s电子的电子云呈球形，电子的最大几率密度分布出现在玻尔半径a0 的球壳内，认为几率密度分布及电子云属统计规律，意味着已经使用了宏观时标，这样就使氢分子体系中能量和时间的作用量远大于普郎克常数；根据电子云的交叠，用经典力学计算了基态氢分子的结构常数，获得键长、键能及力常数的表达式分别为Re=2a0 ，De=ze/4 2a0 ，k=ze/2 2a30 ，采用原子单位 a 。u 。

After thecomplete genome extraction of the strain was performed, the genomic DNA was partiallydigested by restriction enzyme Sau3AⅠ, the DNA fragments from 1 to 5Kb was clonedinto prokaryote expression vector pET-28a-c, and transformed host bacteria. The resultsshowed that we succeeded in constructing the gene expression library of haemophilusparasuis serovar 5, which is fundamental for the study of advanced gene screening. Inaddition, primer design was performed based on haemophilus influenzae in this study. In addition, PCR was performed by using genomic DNA of haemophilus parasuisserovar 5 as the template. The results demonstrated that we obtained two neo-gene:23SrRNA gene(conserved gene belonging to the large-subunit of ribosome) and adenylatecyclase gene(encodes adenylate cyclase and participates in converting adenyl nucleosidetriphosphate to cyclic adenosine3",5"-monophosphate). Furthermore, the phylogeneticanalyses between the species was performed, and neighbor-joining tree was constructedbased on comparison of 23S rRNA gene sequences, so it was illuminated betweenHaemophilus parasuis and other species in molecular evolution relationship.

The results showed that the reaction activity between glycinin (7S subunit) and maltodextrin was high, and the reaction proceeds quantitatively regardless of the variation of protein and polysaccharide mass ratio. The molecular properties of the formed conjugates are also highly uniform. The reaction activity between β-conglycinin (11S subunit) and maltodextrin is relatively lower Compared to that of glycinin, and the molecular properties of these conjugates are affected by the variation of the R values.

To obtain a better understanding of the microbiota inhabiting the intestinal tract of wood-feeding lower termites, the European subterranean termite, Reticulitermes santonensis (Isoptera: Rhinotermitidae), was used as a model system. The diversity and structure of the bacterial community in the different niches of the gut, as well as the distribution and location of major bacterial phylotypes within the intestinal tract was evaluated using various molecular techniques such as clonal analysis, DNA fingerprinting, and fluorescence in situ hybridization. In addition, the symbiotic bacteria associated with the flagellate, Pyrsonympha vertens in the gut of the closely related Eastern subterranean termite, Reticulitermes flavipes , were phylogenetically characterized.

Between 4-9L exposures, C2H4 has a desorption channel at 155-180K. C2H4 desorption at 130K maybe results from BrCH2CH2Br absorbs in Br atom toward surfaces, after C-Br bond scission, because C2H4 has no opportunity to touch surfaces so it desorbs at low temperature. C2H4 desorption at 210K is likely to be desorption limited that, BrCH2CH2Br docomposes to C2H4, only to desorb at higher temperature. This C2H4 desorption channel maybe comes from defect site desorption.

曝露量在4-9L之间，C2H4在155至180K的范围内也有脱附的管道。130K的C2H4脱附可能是因为BrCH2CH2Br分子以Br原子朝向表面的方式吸附，在断了C-Br键后，C2H4分子没有机会接触到表面在低温就脱附了。210K的C2H4可能是脱附所决定的，亦即BrCH2CH2Br分解后在表面形成C2H4，随后温度升高至较高温才从表面脱附，此C2H4管道也许是来自缺陷位置上的脱附。
