New ruthenium benzylidene complexes benzylidene[1,3-bis(2,6-dimethylphenyl)-4,5-dihydroimidazol-2-ylidene] [k~2-diphenylphosphinoacetato] monochlororuthenium (46), benzylidene[1,3-bis(2,6-dimethylphenyl)-4,5-dihydroimidazol-2-ylidene][k~2-3-propionato]monochlororuthenium (47), benzylidene[1,3-bis(2,6-dimethylphenyl)-4,5-dihydroimidazol-2-ylidene] [k~2-2-benzonato]monochlororuthenium (48) featured five-membered, flexible six-membered and rigidsix-membered chelating rings respectively are prepared by reactions of complex 41 withcorresponding sodium phosphino-carboxylates. It is confirmed by X-ray crystallographicanalysis that the coordination geometries of complexes 46 and 47 are distorted squarepyramids with phosphino-carboxylate ligands chelating to ruthenium, and the coordinationbetween ruthenium and benzylidene ligands are strengthened.

用二苯基瞵乙酸盐、二苯基膦丙酸盐、二苯基膦苯甲酸盐与钌卡宾配合物41反应合成了三个新的钌卡宾配合物：含五元膦-氧螯合环的1，3-二-(2，6-二甲苯基)-4，5-二氢咪唑基1-苯亚甲基--一氯合钌(46)、含六元柔性膦-氧螯合环的[1，3-二-(2，6-二甲苯基)-4，5-二氢咪唑基1-苯亚甲基--一氯合钌(47)及含六元刚性膦-氧螯合环的[1，3-二-(2，6-二甲苯基)-4，5-二氢咪唑基]-苯亚甲基--一氯合钌(48)。X射线单晶衍射分析证明，配合物46、47都为变形的四方锥构型，膦-氧与钌形成螯合配位，其中苯亚甲基与钌的配位得以加强。

晶体结构分析表明，该配合物中存在 [Cu2]2+、[Cu2(H2O)]2+和[Cu6(H2O)65Cu24]4-三种配位离子，铜原子呈现四种不同的配位数和几何构型，它们是：4配位的平面四边形；5配位的四方锥型；6配位的八面体型；7配位的三角双锥型。

Today, the world is goinging to a time of knowledgement and a time of informationJt is a background for China to explores the talents and to reform the ?pearonnel matters. Under this background, the states of china exploration, f talents is not good, and has 4 main questions in it, for example ,the lose of talents in china is serious. So we should use some measures to solve theses questions.

本论文论述了当代中国人才开发和人事制度改革所处的国际背景，即世界已经进入了一个的知识经济时代，是一个的经济全球化的时代，以及在这样的时代背景下，当今中国中在人才开发上的现状，主要存在着四方面的问题，包括人才流失十分严重等等。

Therefore, a revised model of the correspondence view is proposed. It compares textual cohesion and textual coherence in terms of etymology and acceptation, research subject, device and function. A conclusion is reached that cohesion and coherence are two interdependent semantic relations that work at different levels within a text and interact with each other to create textuality.

该模式从语源和语义、研究对象、具体手段和功能等四方面对篇章的衔接和连贯进行了对比，结论认为衔接和连贯是篇章中固有的两种语义关系，都有各自的实现手段，分别在篇章的微观和宏观层次上起着连接篇章成分的作用，相互影响作用，共同赋予篇章以篇章性。

The article summaries the progress in study of cognitive impairment after thalamic stroke from four aspect which covered neuropsychological mechanism of thalami participating in cognition, the sorting of thalamic stroke, estimating method of cognitive function after thalamic stroke and the status of clinical study of thalamic stroke.

脑卒中后认知功能损害已成为临床神经心理学的研究热点，本文从丘脑参与认知神经心理的机制、丘脑卒中神经心理学分类、丘脑卒中认知功能评价方法、卒中的临床研究概况等四方面对丘脑卒中后认知功能损害的研究进展进行了总结，以期有利于丘脑卒中治疗方案和康复计划的制定，减少丘脑卒中带来的认知功能损害。

The coordination geometry of the Eu atom is best described as a strongly distorted square-antipyrism.. The two Eu atoms are bridged by two N-oxide oxygen atoms forming a dimeric unit with crystallographic inversions centre. The Eu……Eu distance is 4.2137(9)〓. The two europium atoms and two bridging oxygen atoms is coplanar. The angles of Eu(1)-O(7)-Eu(1A) and O(7)-Eu(1)-O(7A) are 117.82(14)° and 62.18(14)°, respectively. 15 is the first dinuclear triboluminescent lanthanide complex reported.

同时还测定了其摩擦发光光谱与其光致发光光谱，并讨论了晶体结构和摩擦发光活性之间的关系。X-射线结构分析表明，15为有对称中心结构的配合物，每个Eu与三个HTTA的六个O原子和两个PyO的两个O原子形成八配位的四方反锥几何构型，2个N-Oxide O原子桥联两个Eu，形成了一个双核配合物，Eu。。。。

But that underground status is part of Foursquare's appeal, its fans say. It is not yet cluttered with celebrities, nosy mothers-in-law or annoying co-workers.

它的爱好着认为，隐秘的姿态是四方会吸引人的一个因素，没有名人的喧闹，烦人的婆婆和可恶的同事。

After he has appeared, his empire will be broken up and parceled out toward the four winds of heaven.

他兴起的时候，他的国必破裂，向天的四方分开，却不归他的后裔，治国的权势也都不及他。

She looked up at last as the vehicle jolted into a great stony quadrangle, which had been the approach to a monastery once, but which was now the coutyard of a dismal hotel, in whose cellars legions of rats skirmished and squeaked even while the broad sunshine was bright in the chambers above.

马车摇摇晃晃进入一个石头砌成的四方大院子时，她抬起头来看看；那地方本来是个修道院的入口处，现在却成了一个阴沉惨淡的旅馆的院子。旅馆上面的房间里尽管阳光灿烂，地下室里却有成群结队的老鼠在大打出手、吱吱乱叫。

The garden, which was slightly arched, had in its centre, on the summit of a hillock, a fine pointed and conical fir-tree, whence ran, as from the peaked boss of a shield, four grand alleys, and, ranged by twos in between the branchings of these, eight small ones, so that, if the enclosure had been circular, the geometrical plan of the alleys would have resembled a cross superposed on a wheel.

园里的地面是微微隆起的，中间有个稍高部分，一株美丽的圆锥形的枞树耸立在那上面，宛如圆盾中心的突刺，四条宽道从那中心出发，伸向四方，每一条宽道又都有两条小路，各向左右分展出去，各各相通，因此那片园地，假使是圆的话，那些道路所构成的几何图形就象一个加在轮子上面的十字架。

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。
