Finally, two tetranuclear Cu~(2+) complexes were constructed from a new salen ligand with alkoxo groups. The two complexes were obtained by the reaction of the same ligand with Cu~(2+) in different solvents, i.e., a stage tetranuclear complex and a pseudo-cubane tetranuclear complex in MeOH and THF, respectively.

最后，本文以Schiff碱类过渡金属配合物发展应用为研究背景，设计并合成了一种新型Schiff碱及其两种构型的Cu金属配合物，发现所设计的具有和三个Schiff碱配体，与Cu_2在不同的反应溶剂中进行配位反应时，可以得到不同结构的配合物。

Surely, our children must be a priority when it comes to invoking a meaningful response to climate change?

毫无疑问，当我们需要唤起人们对气候变化的更加有意义的反应时，我们的孩子难道不应该是最佳的听众吗？

In the first students, both the mean of latencies and the mean of errors of subtraction were obviously higher than of addition.

在二年级、三年级、四年级，每个年级加法的反应时和减法的反应时非常接近；只有一年级，减法的反应时均值明显高于加法的反应时。

So, thanks to the hard work of Alfa Romeo and Magneti Marelli, the car is responsive and reliable when you turn the steering wheel or put your foot on the accelerator.

所以，感谢的阿尔法罗密欧和Magneti Marelli的努力，赛车和可靠的反应时，你把方向盘放在加速器你的脚。

Every educator should always focus on our own moral character and self-cultivation,make our efrorts to practise what we preach,to seek truth from facts,and to influence our studems in our own words and deeds.we must have the spirit of lifelong leaming and innovation.

学高为师，身正为范，每个教育工作者都应时时、处处重视自身的品德修养，力争做到言行一致，实事求是，以自己的言传身教去影响自己的学生；要有终身学习和创新的精神。

The perturbation methods are the common analyzing method for studying thevibratory response of the mistuned bladed disk, but different perturbation methodshave their own relying conditions on the system parameters. In this dissertation, threekey perturbation methods are studied for their application conditions. Their relyingconditions on the system parameters are summarized.

本文对三种常用摄动法的构造特点及其适用性进行了研究，总结了它们在分析失谐叶盘系统振动响应时对于系统参数的适用条件；针对自适应摄动法在分析失谐叶盘系统振动响应时，对于基系统模态的选择难以控制的问题，提出了一种模态自动选择法。

Moreover,utilizing the theory mentioned above,the value of the peak factor about the wind-induced vibration of roof structure was obtained,The results show that the prescript of peak factor in Chinese code is probably unsafe for the wind-resistant design.

该算例的分析结果表明：当采用我国荷载规范规定的峰值因子取值来计算屋盖结构的风振响应时，其结果可能是偏于不安全的。

The coordinated COD of 3 and 4 can be replaced by carbon monoxide to yield the corresponding dicarbonyl species [(C,N-pyN^C-R) M2]BF4 (14, M= Rh; 15, M= Ir). Ligand substitution of 11a by phosphines and azide causes the de-complexation of pyridinyl-nitrogen donor to generate the corresponding carbene rhodium complexes [(C-pyN^C-Mes)RhPR3] (17a, R = Ph, 17b, R = Et) and [RhN3] (19), respectively, indicating the labile nature of steric-hindered pyridinyl-nitrogen donor.

螯合错合物的吡啶配位，可以容易被σ-予体，如卤离子、叠氮阴离子、膦试剂，置换；但是铑与铱金属螫合物与π-酸试剂，如一氧化碳、异腈，则发生COD被置的产物14a与16；与三甲基亚磷酸酯反应时，COD及吡啶均会被取代而得到单芽的三铑-碳烯错合物18；双膦化合物则会取代铑金属上全部的配位基。

Once this" sludge" reacts with the acid, it will break down and be absorbed by the intestine faster than the solid food.

当那些被消化而成的&烂泥&的食物对酸性物质起反应时，会被肠吸收的快。凝固的物质将难以被肠吸收。

A novel Ziegler-Natta type catalyst for the hydrogenation reaction of isooctene to isooctane was developed by investigated the effect of the solvent and the ratio of aluminium/nickel on the conversion,and the influence of process conditions on the hydrogenation reaction by Ziegler-Natta type catalyst was also studied.

探讨了在Ziegler-Natta型均相催化剂上进行异辛烯加氢反应时，催化剂中的溶剂和铝/镍质量比对反应转化率的影响，得到了优化的Ziegler-Natta型均相催化剂，并考察了工艺条件对异辛烯加氢反应的影响。

In the negative and interrogative forms, of course, this is identical to the non-emphatic forms.

。但是，在否定句或疑问句里，这种带有"do"的方法表达的效果却没有什么强调的意思。

Go down on one's knees;kneel down

屈膝跪下。。。下跪祈祷
