过渡

It was very interesting to find that the carbonate species on the O2/Ov/CeO2(110) surface desorbs to CO2 through the bidentate and monodentate intermediates.

过渡态计算发现，O2/Ov/CeO2(110)表面的三齿碳酸盐物种经两齿、单齿过渡态脱附生成CO2。

The results show: 1 In the rapid urbanization, the human activities in Beijing area are becoming stronger and stronger with the accelerating trend; 2 The rapid expansion of the urban land by encroaching the cultivated land in the plain area and the land use adjustment within the no-urban area are the main characteristics of the land use/cover change in Beijing; 3 The land use/cover from the center city, the fringe area to the exurb area show the obvious character of the spatial-temporal grads change with the most strong changes taking place in the fringe area.

发现：1伴随着快速的城市化进程，北京地区人类活动对区域整体的改造和影响正在深入，并且表现出加速趋势；2城镇用地通过占用耕地在平原区的快速扩展和非城镇用地内部的结构调整是北京地区土地利用/覆盖变化的基本特征。3从北京城市核心区经城乡过渡区到郊区，土地利用/覆盖变化表现出明显空间分布和时间变化上的梯度性，其中城乡过渡区是北京地区土地利用/覆盖变化最明显、也是最剧烈的区域(第4章)。

After a brief fightback that culminated in the ghastly Thirty Years War in 1618-48, Europe moved smoothly towards the Enlightenment and today's ideal of secular tolerance.

在天主教的短暂回击并最终引发1618年-1648年的三十年恐怖战争之后，欧洲平稳地过渡到18世纪的启蒙运动，并进一步过渡到今日宽容的完美境地。

This paper deals mainly with the stray current distribution in running tunnel of metro by means of analytical method of equivalent circuit diagram and the analytical method ,and discusses the influence of resistance of rail to ground and the resistance of track on the variation of stray current.

利用等效电路分析法和解析法分析了地铁区间隧道中杂散电流的分布，探讨了轨地过渡电阻值以及走行轨阻抗对杂散电流变化的影响，得出轨地过渡电阻的降低和走行轨阻抗的增大是区间隧道中产生杂散电流的主要原域。

The reaction was assumed to be an electronphilic attack of nitrosonium on imines, resulting a four-member ring intermediate.

推定该反应经历了一个四员环过渡态，在过渡态中通过化学键的断裂与重组生成了相应的重氮盐和芳香醛。

Baths and immersions also have a natural kinship with rites of passage, the ceremonies that mark the transition from one stage of life to the next—from being an anonymous infant to a named member of the community, from singlehood to marriage, from life to death.

沐浴和洗礼也自然地密切相关，后者伴随一些&过渡仪式&，标志着一个人的生活从一个阶段过渡到另一个阶段：从无名婴儿到有名有姓的团体成员，从单身到成家，从生到死。

Electrocatalysts, such as metals, metal alloys, transition metal oxides, transition metal macrocycle etc, for oxygen reduction reaction in fuel cells and metal-air batteries were reviewed .

主要综述了近几年燃料电池、金属-空气电池中氧还原反应催化剂的发展状况，包括发展成熟的贵金属及合金；过渡金属复合氧化物、简单氧化物；过渡金属大环化合物以及双功能电催化剂研究现状。

It was found that earlytransition metal monoxides ScO, TiO and VO do not form noble gas complexes, whilethe late transition metal monoxides coordinate one noble gas atom in forming thelinear NgMO(M=Cr, Mn, Fe, Co, Ni) complexes.

对于前过渡的ScO，TiO和VO分子，它们的9σ，1δ和4π价分子轨道能量很高，不能有效地与稀有气体原子形成络合物，而对于后过渡金属一氧化物则可以配位一个稀有气体原子形成直线型的NgMO(M=Cr，Mn，Fe，Co，Ni)络合物。

The valence electron number is N_=4(s~2d~2), N_v=5(s~2d~3), N_=6(s~1d~5),N_=5(s~1p~4) for the transition elements Ti, V, Mo, Nb, respectively, and N_=3(s~2p~1) for thenon-transition element Al.

过渡族元素Ti，V，Mo，Nb的价电子数分别为4(s~2d~2)，5(s~2d~3)，6(s~1d~5)，5(s~1d~4)非过渡族元素Al的价电子数为3(s~2p~1)。

By adding the Presentation Interlayer and the Logic Interlayer from the point of view of logical level, the system can pool large numbers of computing and net flow onto agent-server side, so it can not only minimize transmission data between the browser and embedded facilities'gateway, and save the limited bandwidth but also improve the response time.

从逻辑层次上该系统通过增加表示过渡层和逻辑过渡层将大量的计算和网络流量集中于智能代理-服务器一边，从而减轻了嵌入式设备的计算负担，减少了浏览器到嵌入式设备网关之间的数据传输、节约有限的带宽、提高了响应时间。

As she looked at Warrington's manly face, and dark, melancholy eyes, she had settled in her mind that he must have been the victim of an unhappy attachment.

每逢看到沃林顿那刚毅的脸，那乌黑、忧郁的眼睛，她便会相信，他一定作过不幸的爱情的受害者。

Maybe they'll disappear into a pothole.

也许他们将在壶穴里消失
