有代表性地

Painting which is the mainstream of the western art is extremely representational in the aspect of the space concept. But relieves combine the paintings'complanation with sculptures'extensity .so we decide to research the process of the evolvement and the interaction between paintings and sculptures. We expect to discuss the space and art expression in the western art and relieve ,so I can have a further comprehension about the space of optical art. The comprehension can not only help us understand the traditional western paintings and relieves better, but also make us comprehend the space concept of modern art better, to set the artistic creations of contemporary paintings and relieves into action.

油画，作为西方绘画的主流形式，在空间形态的表现上极富代表性，而浮雕兼具绘画的平面性与雕塑的实体空间性，因此，我选择研究油画与浮雕在空间上的演变过程及其相互影响，以期可以从一个侧面来探讨西方绘画与浮雕中的空间观和艺术形态表现，从而对视觉艺术的"空间"有更深一个层次的了解，这不仅有利于我们理解传统的西方油画和浮雕，也能使我们更好地理解现代艺术的空间观念，进而更好的推动当代的油画和浮雕创作。

As the globalization goes, people are paying less time for traditional rituals and ceremonies. Thus, some people then worry that this would lead to a diminished sense of who we are. However, I personally believe that the worry is unnecessary, for even if rituals and ceremonies help define a culture, they does not contribute to our true self-knowing.

攻击点：仪式和典礼确实是文化的代表性产物，但并非文化最重要的部分，是人们为了强烈地表达自己的文化从而发明了仪式来服务于文化，尽管如今全球化仪式典礼淡化，但文化中的其他因素仍然能够帮助人们对自己有定义认识

There are about 100 species plants in the wetland, and the majority is herbage and frutex. These plants included Polygonum hydropiper, Nelumbo nucifera, Annua Linn, Phragmites communis etc. At the same time, there are also 48 species animals, which belong to 30 families, and these animals included Ciconia ciconia, Cygrus cygrus, Platalea leucorodia, Meles meles etc.

湿地内有高等植物近100种，其中草本和灌木占大多数，典型的如水蓼、莲藕、早熟禾、芦苇等；在此栖息的动物有5纲共18目30科48种，具有代表性的如黑鹳，大天鹅、白琵鹭、狗獾等，是铜川市重要的水源补给地和湿地保护区，对于当地生态环境和经济社会可持续发展意义重大。

These compounds are of substantial interest both inviewpoints of theory and practical applications, mainlyunder the stimulus to achieve synthetic models either foractive sites of iron-sulfur proteins or for transitionmetal catalysts. This thesis describes the synthesis, structures andconformations of 51 new iron-sulfur cluster complexes,which have been characterized by elemental analysis andstandard spectroscopic methods. In addition, single-crystalX-ray diffraction analyses were performed for 4 representa-tive new compounds. Reactivities of μ-〓 with mono- and di- Grig-nard reagents derived intermediates toward various organicelectrophilic substrates were studied, along with complexa-tion of arynyl-containing iron-sulfur clusters by 〓Thus, several bridged, non-bridged, monomeric, dimeric,homonuclear, heteronuclear iron-sullfur and iron-sulfur co-balt-carbon cluster complexes were synthesized. A novelreaction and convenient route for the synthesis in highyield of tetranuclear iron complexes 〓 containing atetracoordinated sulfur atom was discovered, whereas aplausible mechanism based on experimental results was propo-sed for the formation of the new cluster type.

Now the perceived threat is again rising in the East, judging by the harrumphing in Congress and a crop of books in the past couple of years, such as Steve Hamm's "Bangalore Tiger: How Indian Tech Upstart WIPRO is Rewriting the Rules of Global Competition" and Ted Fishman's "China Inc: How the Rise of the Next Superpower Challenges America and the World".

From 6860 to 3170 cal.yr BP,semi-desert steppeexpanded,regional montane forest steppe retreated,suggesting a prolonged warm and dryclimate.Between 3170 and 2340 cal.yr BP,regional forest steppe expanded whereassemi-desert steppe retreated,indicating the climate became cool and wet gradually and thehumidity reached the maximum at the end of this stage.During 2340～1600 cal.yr BP,Poaceae steppe dominated whereas wetland meadow expanded and the montane forest stepperetreated,suggesting a cool and wet climate prevailed,wormwood grass steppe prevailed andthe climatic instability increased after 1600 cal.a BEThe climate and environmental reconstructions by pollen were supported by the diatomrecords.A relative high lake level and moister climate prevailed between 8660 and 7230 cal.yr BP as inferred by the dominance of planktonic diatom genera and high planktonic/benthicratio (〉40).low lake level and dry climate sustained during 7230～2330 cal.yr BP assuggested by the low abundance of planktonic diatom and low planktonic/benthic ratio ～20and the lake returned to high level during 2330～930 cal.yr BP as inferred by there-dominance of the planktonic diatom and the high value of palnktonic/benthic ratio.The pollen-based climate reconstruction was also consolidated by the grain size andPediastrum concentration records.
