查询词典 ionic bond

The strain of sheet mainly occurs in loading end in the initial load. With the increase of load, the strain extends to the remote end; the bond stress gradually reduces from the loading end to the remote end; the peak bond stress locates slightly away from the loading end. For 16.3% moisture content, the effective bond length between BFRP and wood is 100 mm.

结果表明，加载初期，纤维布上的应变主要存在于加载端附近，当荷载逐渐增加时，应变也向加载远端增大；随着与加载点距离的增加，粘结应力逐渐降低；随着荷载的增加，粘结应力峰值位置向远离加载点方向稍有移动；在含水率为16.3%条件下，BFRP与木材的有效粘结长度为100mm。

Junk Bond A bond that is rated by a ratings agency as being below investment grade and investment in the bond is high risk.

最后的结论是，中国零息票债券收益率曲线构造的约束条件主要有交易所债券市场样本不足和银行间债券市场数据失真。

As used herein, a highly unsaturated hydrocarbon is defined as a hydrocarbon containing at least one triple bond, conjugated carbon-carbon double bond, or cumulative carbon-carbon double bond.

本文所使用的高度不饱和烃定义为含有至少一个叁键、共轭的碳碳双键或累积的碳碳双键的烃。

This kind of halogen bond is between covalent and ionic interactions, with the static interaction being dominant.

复合物体系中的卤键介于共价键与离子键之间，偏于静电作用成分为主。

On the other side, F is more electronegative than O, so Mn-F bond is more ionic in nature than Mn-O, and substitution of F for O will enhance the chemical stability of the spinels.

当然F／O间电负性的差别使得Mn-F比Mn-O具有更强的离子性，F取代O也增强了材料的化学稳定性。

The combination energy includes hydrogen bond energy and electrostatic energy of ionic-pair,and contribution of the later is main.

分析晶胞发现每一个晶胞包含四个EM IM+/C l-离子对，测定咪唑环上C2和C l原子的距离为0.355 nm，认为C2-H…C l间形成了氢键。

The compound is an ionic compound consisting of a cation NH(subscript 4 superscript +) and an anion C6H2N3O(subscript 9 superscript -), and it is the mono-substituted salt of TNPG. Since the existence of complicated hydrogen bond networks and electrostatic attraction between NH(subscript 4 superscript +) cation and C6H2N3O(subscript 9 superscript -) canion, the compound possesses better stability and low sensitivity.

该化合物是由一个铵根离子与一个一价的三硝基均苯三酚负离子相结合而形成的离子型化合物，分子中存在的大量氢键及铵根离子与三硝基均苯三酚负离子之间的静电引力使得该化合物具有较高的热稳定性和较低的感度。

The interactions of dsDNA and ssDNA with two osmium complexes have been studied by surface electrochemical methods based on DNA modified electrode. It is found that both osmium complexes bond DNA with electrostatic interaction. And some thermodynamics and kinetics constants, such as bindind constant , ratio of binding constants K〓/K〓, limiting ratio K〓°/K〓°at zero ionic strength (μ＝0), free energy ΔG〓, dissociation rate constant k and binding site size s have been obtained.

研究发现两种锇配合物都是通过静电作用与DNA结合，并计算得到联吡啶锇和二氯菲咯啉锇与dsDNA和ssDNA相互作用的结合常数、结合常数比K〓／K〓、μ＝0时极限结合常数比K〓°／K〓°、结合自由能ΔG〓、解离速度常数k和结合位点数s等多个热力学和动力学参数。

Electrovalence:Valence characterized by the transfer of electrons from atoms of one element to atoms of another during the formation of an ionic bond between the atoms.

电价：在原子间形成离子键的过程中，由电子从一种元素的原子转移到另一种元素的原子所表示的价。
