The result indicates that the hyperconjugation effect from lone pairs on nitrogen atoms to germinal N-N bonds can play an important role in the N-N bond length. The N-N bond length displays reverse dependence on the charge density in bond critical points obtained from AIM.

NBO分析表明N原子孤对电子到相邻的氮氮键的超共轭作用是影响氮氮键长变化的主要因素，AIM计算的氮氮键的键临界点电荷密度与键长呈反比关系。

As bond investment management managing complex than equity investments, bond fund management fees are relatively low, our country's bond funds income stability.

由于债券投资管理不如股票投资管理复杂，因此债券基金的管理费也相对较低，目前我国债券型基金的收益稳定。

Meeting添富enhance income bond fund manager Lei Lu said that from a long-term perspective, the bond market will enter a period of rapid expansion, in the current corporate bonds, corporate bonds, based on the future of some of the new trading systems, or new products that may be launched, which will also invest in bond funds to provide more space.

汇添富增强收益债券基金经理雷炉说，从长远的角度来看，债券市场将进入目前的公司债券，公司债券的新交易系统的一些未来的基础上，迅速扩张期，，或可能推出，这也将投资于债券基金，以提供更多空间的新产品。

The chemical bonding is formed the between coating and the substrate. The bond shows a mixed property of covalent bond and ionic bond.

镍晶格和基体粒子之间产生了键合作用，形成的键显示出共价键和离子键的混合性质。

Usually, they are suitable to mixed crystals with metallic bond but not to those with covalent bond or ionic bond.

上述近似方法通常适用于金属键混晶系统，但对于共价键或离子键混晶系统计算结果则不理想。

Results indicate that non-covalent bonds, including hydrogen bond and hydrophobic reaction contribute most to the coagulating reaction, while ionic bond and disulfide bond have little effect on the coagulating process.

结果发现凝固过程中的分子间作用力主要是氢键和疏水作用，而离子键和二硫键对凝固过程影响不大。

There are many factors that determine the ionic bond and covalent bond. What kind of chemical bond is formed between two atoms does not only have connections to the atom itself.It is related to the price attitude of the iton.

决定离子键、共价键的因素比较多，两原子之间形成哪种类型化学键不仅与原子本身性质有关，还与形成的化合物中离子的价态有关。

The result also indicated that variation in atomic neighbour distance with concentration is about 40 percent and 20 percent, respectively, for ionic bond and covelent bond solid solutions, compared with that expected by the near neighbour vegard's law, while in the metallic bond solid solutions, this exceeds 50 percent, even reaches 80 percent 〓 so.

用虚晶格近似模型来描述固溶体中的原子近邻结构是不恰当的，然而原子近邻距的加权平均却与VCA值一致，这说明固溶体晶胞参数随成分的变化规律是由原子近邻距随成分的变化规律所决定的。
