查询词典 ionic bond

Results show that intramolecular hydrogen transfer is not favored in view of the energy trend along IHT coordinate in the region such as hypericin's peri region, where two hydrogens of hydroxyl groups bond with a common oxygen of carbonyl group and exists two IHBs in the peri region. However, intramolecular proton transfer often occur in the molecule with hexahydric cycle hydrogen bond, where only one pair of adjacent hydroxyl group and carbonyl group.

此外选择设计了一个具有三个分子内氢键的体系，兼具金丝桃蒽酮和其他苝醌类光敏剂的分子内氢键特点，研究表明两个羟基氢与共同的羰基氧形成的氢键由于存在较高的势垒，很难发生分子内氢传递，即具有金丝桃蒽酮端位结构的分子其分子内氢传递很难发生，而一般的能形成六元环状结构的分子内氢键体系容易发生分子内氢传递。

因此，我国开展不良资产证券化业务的障碍并不在于不良资产本身的资产质量低，而是由于我国资产证券化运作环境中存在障碍。

The regression analysis was used to test the hypothesis. The results were list as follow:(1) Relationship marketing bond types have significant positive influence on relationship quality and switching cost, where the structure bond is the most influencer.

采用回归分析检定研究假，实证结果发现：(1)关系销结合型对关系品质与转换成本有显著的正向影响，其中皆以结构性结影响程最大。

The Diels-Alder reactions forming one C—B bond and one C—C bond are always more favorable than the corresponding Diels-Alder reactions forming two C—C bonds, both thermodynamically and kinetically, which is in agreement with experimental observation.

形成一个C—B键的杂Diels-Alder反应都比相应的Diels-Alder反应在热力学和动力学上容易进行，这与实验结果一致。

The chemical bond properties of the magnetoplumbite type compound LaMAl11O19 have been studied by using the average band-gap model of the complex crystal chemical bond.

利用复杂晶体化学键的平均能带模型研究了LaMAl11O19晶体的化学键性质。

Over the past week better news about the health of America's "monoline" bond insurers caused stockmarkets to rally and bond spreads to fall.

I thought they wanted me to play Bond so I had an English guy ring up the 007 production office and they told him that the director had seen HARD BOILED and really wanted me to play one of Bond's nemeses in the new movie.

他们告诉他，导演看到我在《辣手神探》中的表演，希望我在新的邦德电影里饰演一个邦德的复仇者。

However the resin aged fast with addition of anatase nano-TiOa P25 for its photoactivate activity. The mechanism of resin under UV radiation as following was put forward: free radicals produced from the surface of nano-TiOj attack the hydrogen of the methylene, then double bond is formed after the dehydrocholrination, and then the chain is broken after the double bond was oxidized by ozone.

锐钛型纳米TiO_2P25明显加速氯醚树脂的老化，通过IR和XPS分析推断树脂老化的机理为：纳米TiO_2表面产生的自由基攻击树脂中亚甲基的氢原子，发生脱氯化氢生成双键；双键被臭氧氧化发生断链裂解。

The results show that both conformations of prolyl peptide bond are not easy to transit from each other supporting the opinion that both of the BPP's bio-characters are from its conformations separately. And the function of BPP may not lie on a conformation. The other peptide bond conformations also have influence.

结果表明，脯氨酸肽键构象不易发生互变，无论哪种构象均不存在向另一种构象转变的趋势，从侧面支持了BPP具有的两种稳定的生物学作用是来自于肽键的不同构象的观点，而且BPP的生物学作用可能也不是取决于某一个肽键构象，其它脯氨酸肽键构象对其活性也存在影响。
