The result of the test shows: in the case of inexistence of chlorin ion, the effect of electrochemical oxidation of ammonia wastewater of the Ti/SnO_2-Sb_2O_3 electrode is better than the Ti/SnO_2-Sb_2O_3-CeO_2 electrodes,efficientry.When there exist 400mg/L chlorin ion,both have perfect effect.

对氨氮的电化学氧化去除试验表明，在不含氯离子的情况下，经过优化的Ti/SnO_2-Sb_2O_3电极的去除效果优于经过优化的Ti/SnO_2-Sb_2O_3-CeO_2电极，但效率不高；而在含有400mg/L氯离子情况下，二者对氨氮均有很好的去除效果。

For salt lake brines, ED exhibits very low efficiencies for removal of trace divalent ions or extraction of trace univalent ions.

Some essential trace elements were reported to be involved in the normal bone metabolism. Nowadays rare earth elements are widely used in many fields and more and more rare earth elements enter the environment and food chains They are enriched in bone and difficult to be excreted. Because the similarity between rare earth ions (Ln3+) and Ca2+, they will intervene and regulate bone formation and remodeling.

骨骼的正常代谢涉及多种金属离子，随着稀土的应用，通过环境和经由食物链等渠道进入人体内的稀土量也有所增加，并且在骨组织中相对富集且难排出；由于稀土与钙离子的相似性，它们将干预和调控骨的形成与再造。

The effects of different center metal ions on third-order NLO properties are discussed. And the conclusion is drawn that the charge transfers from macrocycle π-orbital to metal d orbital make the substantial contributions to microscopic hyperpolarizability.

论文的第三章选择系列酞菁化合物作为研究对象，讨论了不同的中心金属离子对三阶非线性光学性质的影响，确认酞菁共轭环平面上的π轨道到金属离子的d轨道电子跃迁对三阶非线性光学极化率起主要贡献。

At experimental equilibrium volume, the total energy of CaTiO〓 increased with the displacement of Ti along [001] direction and the lowest energy point is always at zero displacement of Ti. However, with a 10% volume expansion, the displacement of Ti along [001] direction results in a shallow, but well-defined double energy well and ferroelectricity appears.

钛酸钙在实验晶胞体积下，钛离子沿[001]方向的位移不会引起总能量的降低，当体积膨胀10％时，钛离子的位移会引起系统的总能量的降低，在一定的位移时总能量呈现极小值，即出现铁电性。

The appearance of electronic conductivity makes the ionic transference number is smaller than unity. Therefore the corresponding mole entropy of oxygen ions decreases with the oxygen partial pressure.

由于电子空穴和电子电导的出现，使得氧离子的迁移率小于1，由此计算出的氧离子迁移的部分摩尔墒随氧分压的减小而减小。

Finally, the antibacterial experiment and ICP analysis reveal that the hollow and solid silver-coated silica particles of the same weight would show a pronounced difference on the release of silver ions for the escherichia coli. Our results show that the hollow structure raises the release effect of silver ion both in the antibacterial experiment and ICP measurement.

By the time of its fall, most of the prisoners were writers who had written against the corruptions of the government.

到它被攻陷的时候，里面多数的犯人是写了反对政府贪污文章的作家。

The most obvious variation to ovum morphological character was that the color was changed from light green to sepiaceous in embryonic development, and all the ovums were almost hatched after 96h.

在胚胎发育过程中卵的形态特征最明显的变化是颜色从淡绿到深褐色，卵在发育96h后卵基本全部孵化。
