Songshan World Geological Park has a total area of 464square kilometers. In the park, aggradation and structure, such as magmatic rock, metamorphic rock and sedimentary rock of the 5periods of geologic history, namely 二 Archean Eon, Proterozoic Eon, Paleozoic, Mesozoic and Cenozoic, continuously and completely crop out, relics of angular discordance interface and structural feature fwature by 3 global Precambrian orogeny and epeirogeny respectively called SongYang motion, Zhongyue motion and Shaolin motion taking place 25billion years,1.8billion years and 546million years ago. This park is called by geologists as" natural geology museum ,of" five generations under one roof .

嵩山世界地质公园总面积 464 平方千米，公园内连续完整地出露着太古宙、元古宙、古生代、中生代、新生代五个地质历史时期的岩浆岩、变质岩、沉积岩等沉积和构造，清晰地保存着发生在距今 25 亿年、 18 亿年、 5.46 亿年前被分别命名为嵩阳运动、中岳运动和少林运动的三次全球性前寒武纪造山、造陆运动所形成的角度不整合界面及构造形态遗迹，被地质学家称为"五世同堂"的"天然地质博物馆"。

Although the result will show the positive relations among the stock price, the interest rate, and the exchange rate by direct quotation, it is not explicable to explore the relationship of those three variables only.

在实证分析部分是以时报资讯-情报赢家2000所提供之1999年1月5日到2005年11月30日的统计日资料为基础，建立最小平方回归模型研究其相互关系，研究结果显示如理论探讨所得结论：股价、利率与直接报价法的汇率三者彼此有著正向的关系，并发现仅仅探讨此三变数的关系是较不具有其解释能力的，因为各变数并非仅有彼此做为唯一的影响因子，尚有些经济的变数会影响它们。

The Pd-Cu/C catalysts were shown to have the face centered cubic crystal structure. This could indicate that the addition of Cu shortened the Pd-Pd distances in the crystal lattice, and therefore –HO(subscript 2ads) and O-O could be better adsorbed on the surface of the catalyst. When NaBH4 was used as the reducing agent, and the atomic ratio of Pd to Cu was 3:1, the resulting catalysts had an average particle size of 3. 4nm and showed the best catalytic performance. The electrochemical active surface are a of Pd3Cu/C was 38.9m^2/gPd and the oxidation reduction reaction activity of the Pd3Cu/C catalyst was much higher than that of the Pd/C catalyst. The electrochemical activity of the Pd3Cu/C catalyst was comparable to that of a commercial Pt/C catalyst.

结果表明：催化剂中Pd与Cu的物质的量之比与预设值相近，Pd和Cu基本被全部还原；Pd-Cu/C催化剂为面心立方结构，元素铜的加入使催化剂的Pd-Pd间距缩小，从而HO(下标 2 ads)和OO键能更好地吸附在催化剂金属表面；当采用NaBH4为还原剂，Pd与Cu物质的量比为3：1时，催化剂(Pd3Cu/C)的平均粒径为3.4 nm，催化剂的催化性能最好，电化学活性表面积EAS达到38.9平方公尺/gPd，电化学性能较Pd/C催化剂有很大提高，接近Pt/C商用催化剂。

The environmental stability of that world - including its crushing pressures and icy darkness - means that some of its most famous inhabitants have survived for eons as evolutionary throwbacks, their bodies undergoing little change.

稳定的海底环境─包括能把人压扁的压力和冰冷的黑暗─意谓海底某些最知名的栖居生物已以演化返祖的样态活了万世，形体几无变化。
