查询词典 Ionic

Since ionic liquids are composed from ions you usually observe one or the other ion depending on the mode used to record the mass spectrum.

因为离子液体是由离子组成的；你通过质谱观察到的通常决定于你使用的模式。

The experimental results indicate that the new ionic liquids possess lower melting point and higher electrical conductivity.

实验结果显示这两个新型的离子液体拥有低熔点和高电导性。

Crystal lattice constants are close to other experiment results. Three kinds of chemical bonds exist among Mg and B atoms, between magnesium and boride is ionic bond and metallic bond is the predominant interaction in the layer formed by magnesium atoms. A strong covalent bond in the form of sp2 hybrid between boride atoms is the most important factors which can affect the transition temperature of MgB2. Population analysis clearly shows that electrons are transferred from Mg to B, as a result, the electron-phonon coupling in the layer of B is very strong.

规范保守赝势的计算结果表明，晶格常数与实验值误差在很小的范围内，分析了引起MgB2(001)面结构超导转变时电子浓度和偏态密度的变化情况，发现构成该超导体结构的成键有3种，着重从结构的电子浓度变化分析了其超导特性，六角蜂窝状结构中硼原子间相互作用为sp2杂化的共价键，镁原子和硼原子之间是离子键结合，镁原子层是金属键结合，镁原子的价电子部分转移到硼原子的pz轨道，部分电子为镁原子层共用。

The bonding energy of the mixed covalent/metallic Ti-Al bond for the Ti-terminated Al/TiB_2 interface is larger than that of the polar covalent Al-B bond with partial ionic-like feature for the B-terminated interface. Metallic bond between Al atoms forms across the Al/AlB_2 interface, which results in weaker interfacial adhesion than that for the Al/TiB_2 interface. The interfacial energy for Al/TiB_2 depends on the interfacial chemical potential.

Al熔体中仅存在TiB_2粒子，而无多余溶质Ti时，α-Al在TiB_2粒子上异质形核产生的Al/TiB_2界面能大于α-Al从Al熔体中直接形核时的液-固界面能，不满足TiB_2粒子充当α-Al有效异质形核核心的能量条件，这从理论上解释了Al熔体内仅存在TiB_2粒子时无晶粒细化效果的实验现象。

It was found that the ionic liquid not only increased the selectivity of methyl methacrylate but also inhibited its polymerization.

结果表明，离子液体PF_6不仅能提高MMA的选择性，还能有效防止MMA的聚合，可起到替代阻聚剂的作用。

A new kind of non-ionic surfactant methyl glucose amide was prepared by using oleic acid, glucose and methylamine as raw materials.

以油酸、葡萄糖、甲胺等为原料合成一种新型非离子表面活性剂油酸改性甲基葡萄糖酰胺。

Based on theoretical research and empirical evidence, the new patch-clamp micropipette electrode system has been good at displacement controlling and gigasealing for cells, but it is necessary to do more experiments for automatically sucking and breaking the plasma membrane and recording the currents of cellular ionic channels.

经过理论研究和实验证明，自行设计的新型膜片钳微管电极系统能很好地实现细胞位移控制和吉欧封接，其细胞自动吸破和记录还有待更多的实验证明。

For example, if coral calcium is added to pure water a large portion of the mineral content becomes ionic.

例如，如果珊瑚钙添加到纯净水大部份的矿物质含量成为离子。

The solubility of ionic liquid shows that it is miscible with organic solvent such as alcohol, ester, etc.
