分子性

Accordingly, aromatic compounds can be divided into three groups and a delocalized π system itself is always destabilized, the dependence of aromatic ring current upon the CT was reveled, and ring rigidity has been defined as a new aromatic index.

据此，我们提出了芳环化合物新的分类准则，揭示了芳香环流起因的必要条件，定义环的刚度为芳香性一个新判据。发现，分子内基团间的局部作用同它们对分子整体性能的影响是完全相反的。

In this paper, the concepts of twelve countable compactness in symmetric topological molecular lattices are introduced.

在对称拓扑分子格中引入12种可数紧性的概念，着重指出了它们在极不连通的对称拓扑分子格中的内在联系。

And 0.949〓 respectively. From the model, the substitution of Pro (119)αto Ala in bar-headed goose Hbα〓β〓 interface, which is unique among bird and mammal Hbs and thought to be critical for the enhanced oxygen affinity in bar-headed goose Hb, causes no significant change in protein structure.

大量的研究工作认为，鸟类和哺乳动物Hb分子中a〓β〓亚基交界面唯一的氨基酸突变：Pro（119）α→Ala对于斑头雁Hb分子O〓亲和性的提高是关键的。

From the statistical analyses of the descriptors used in the evolution procedure, three of them, including the partition coefficient (APlog98), indicator, E-State key were found to be the principal features affecting the biological activity, which supplies a guide for the design and reconstruction of new Ribonucleotide Reductase Inhibitors.

同时，通过分析在遗传优化过程中分子参数出现的频度，还得到了可能对活性影响较大的几个重要分子参数，它们分别是水／辛醇分配系数(ALogP98)、指示因子以及电性拓扑态指数。对该类抑制剂的设计和改造提供了指导。

This indicates that these HA have similar compositions, but different structures and properties.Results from analysing E465/E665 are the same as those obtained by analysing molecule structure using colour index coefficientΔ~ K.Compassion study of HA in NaOH and NaHCO_3 solutions show that the absorption peaks shift towards the direction of longer wavelength.

这几个吸收带的变化证明了以紫色潮土HA、石灰性黄壤HA、中性紫色HA、酸性紫色HA、腐殖土HA为序的腐殖酸的芳构化度降低、缩合程度下降的观象，说明腐殖土HA其分子在苯环C骨架的聚合程度、芳构化度和分子复杂程度等上均最小，与紫外光谱分析结果一致。

Its research interests include: psychiatric genetics, particularly the dementias and schizophrenia; clinical and molecular genetic studies; genetic epidemiology of Alzheimer's disease; psychiatric reactions to trauma, including the treatment of post-traumatic reactions and biological markers of such reactions; molecular neuropathology of Alzheimer's disease.

该系的研究兴趣包括：精神病遗传学，尤其是痴呆和精神分裂症；临床和分子基遗传学研究；阿尔海默茨病疾病的遗传流行病；对创伤性精神病学反应，包括创伤后治疗反应和这些反应的生物学标记；阿尔海默茨病疾病的分子神经病理。

Small molecule son of water soluble and permeability, strong, can dissolve away our redundant lipids and garbage, makes us more clear bowel, can promote haemal circulation, In addition, small molecule of water also favors the cells to absorb more advantageous, promote metabolism.

小分子团儿的水，溶解性和渗透性较强，可以溶解掉我们体内多余的脂类和垃圾，使得我们的肠道更加畅通，可以促进血液循环；另外，小分子团儿的水也更利于细胞吸收，更利于促进新陈代谢。

And it has homologs in primate.

同源性分析表明，它很有可能是哺乳动物体内的一种先天性免疫效应分子b-defensin家族中的一员，在灵长类中也有同源分子存在。

The results are as follows: 1 The ingroups studied are divided into four clades on the molecular phylogenetic trees that we reconstructed.

我们测定了斑腿蝗科10亚科20种蝗虫和其它蝗科3种蝗虫的16S rDNA序列片段，并从GenBank中下载了斑腿蝗科3种、其它蝗科10种及蚱总科2种的16S rDNA相应序列片段，然后对这共计38种蝗亚目昆虫的16S rDNA序列片段进行了同源性比较，以其中2种蚱作外群构建了蝗总科的分子系统树，得到的结论如下：1斑腿蝗科并非是一单系群。2该科中的切翅蝗亚科、稻蝗亚科、黑蝗亚科、秃蝗亚科、卵翅蝗亚科、蔗蝗亚科均不是单系群，分子系统树的聚类结果与基于形态特征的斑腿蝗科的分类体系有较大的出入。3支持将黑蝗亚科和秃蝗亚科合并为一个亚科——秃蝗亚科。4卵翅蝗、伪稻蝗和稻蝗三者有很近的亲缘关系。

Macrocycle with two aryl oxdiazolesThe structure of this type of macrocyclic compounds with two aryloxdiazoles attached to the nitrogen atom of amino acids is different fromthat of the above compounds.

三。含双噁二唑的大环：在这类分子中两个芳基噁二唑通过氨基酸的氮原子连接成环，而将手性中心和羧基端放于环外，这可提高分子的络合性能。

The labia have now been sutured together almost completely.The drains and the Foley catheter come out at the top.

此刻阴唇已经几乎完全的缝在一起了，排除多余淤血体液的管子和Foley导管从顶端冒出来。

To get the business done, I suggest we split the difference in price.

为了做成这笔生意，我建议我们在价格上大家各让一半。
