In the presence of Ru, the onset of methanol adsorbate oxidation is shifted to the more negative potentials.

在Ru存在下，甲醇吸附物在Pt电极上氧化的起始电位向负电位移动。

This would indicate that the reaction between OH〓 and methanol adsorbate on Pt-Ru is the rate determining step.

这似乎意味着在Pt-Ru电极上甲醇吸附物氧化的决速步是吸附物与吸附的OH根之间的反应。

The transition density matrix shows that there is electron-hole coherence between Ru and ammine.

第三，跃迁密度矩阵揭示了Ru和ammine上的电子空穴对的相关性。

The charge difference density shows that all the holes are localized on the Ru and the electrons on the ammine. The localization explains the MLCT on excitation.

第二，电荷差异密度揭示了所有的空穴都在Ru上，所有的电子都在ammine上。

The sulphur atom in the intermediate has sp2 hybridization, and the remaining p orbital is symmetrical to the d orbital of the metal center. Thus, the lone pair on the p orbital can have interaction with the d orbital to form a π bond, which leads to the coplanarity of the center of Cp ring, Ru, P, S and Si atoms, rather than the deviation of P, S and Si atoms from the plane.

该中间体中，硫原子采取sp2杂化，硫原子剩余的一个p轨道与金属中心上的d轨道具有相同的对称性，因而该p轨道上的孤电子对可与金属中心上的d轨道形成π键，导致Cp环中心， Ru， S1， P和Si原子在同一平面内，而不是S1， P和Si原子偏离该平面。

The exchange field is found to change in an exponential function of 1/|t〓-t〓| in two wedged synthetic antiferromagnets FeMn/Co (t〓=12. 0nm)/Ru (0.7nm)/Co and FeMn/Co /Ru (0.7nm)/Co (t〓=12. 0nm). It has opposite signs and different magnitudes in above two series.

实验上制备了两个系列的楔形样品FeMn／Co／Ru（0.7nm）／Co，其中t〓=12.0nm及t〓变化和t〓=12.0nm及t〓变化，发现交换偏置场与厚度呈〓关系，而且这两系列样品交换场的符号相反。

Two novel"black"dyes KRu〓(ttp-COOH= 4'-p-COOH-phenyl-2, 2', 6', 2-tpy) and trans-Ru (4, 4'-dcbpy)〓〓 were synthesized, their photophysical properties in solutions and photo-electric properties adsorbed on the surface of nanocrystalline TiO〓 were studied.

研究了两个"黑色"染料trans-Ru(4，4'-dcbpy)〓〓和KRu〓(ttp-COOH＝4'-p-COOH-phenyl-2，2'，6'，2-tpy)的光物理性质及其在纳晶TiO〓薄膜电极上的光电转换性质，二者在红光区的光谱响应范围均比cis-Ru(4，4'-dcbpy)〓〓的宽，能吸收大部分的太阳光，确实在长波区增加了光谱的敏感性。

In the presence of cobalt ion, nearly 100% selectivity to ortho-chloroanilinewas achieved over PVP-Ru/Pt colloids at 100% conversion of o-CNB, with an activity twoorders of magnitude higher than that of monometallic PVP-Ru colloid.

当在反应体系中加入钴离子时，邻氯硝基苯被高选择性地氢化为邻氯苯胺(邻氯硝基苯转化率为100%时，选择性～100％)，同时，反应的活性比PVP-Ru单金属胶体提高了约两个数量级。

Trace Ru could sensitively catalyze the fading reaction of chlorosulphophenol azo rhodanine with KClO3 in H2SO4 medium in water bath at 85 ℃, and the fading level was in direct proportion to Ru in certain content range. Based on this, a novel determination method of trace ruthenium was established by catalytic kinetic spectrophotometry.

H2SO4介质中，水浴85℃条件下，痕量Ru能灵敏地催化KClO3氧化氯磺酚偶氮罗丹宁的褪色反应，且褪色程度与钌含量在一定范围内成正比，据此建立了催化动力学光度法测定痕量钌的新方法。

The experimental results also indicated that the adsorption of DME is likely to be rate determined step in the DME oxidation process and was suppressed with the addition of second metal Ru.

进一步实验还表明了二甲醚的吸附是一个弱吸附，其吸附步骤是氧化的限制过程，而且Ru的加入一定程度上也抑制了二甲醚的吸附，即Pt和Ru的比应有一个优化值。

The split between the two groups can hardly be papered over.

这两个团体间的分歧难以掩饰。

This approach not only encourages a greater number of responses, but minimizes the likelihood of stale groupthink.

这种做法不仅鼓励了更多的反应，而且减少跟风的可能性。
