To bring both cars home in only their third Grand Prix was a great achievement for Super Aguri, especially as Ide's SA05 was reportedly doing display-car duty outside an Australian burger bar only two months ago.

对超级亚久里车队来说，在第三站大奖赛能让两部赛车顺利完赛是一次伟大的进步，尤其是两个月之前，井出有治的SA05还在澳大利亚的burger酒吧扮演着展示赛车的职责。

Three altimeter data——Geosat/GM, ERS-1/35day and Topex/Poseidon, and two gravity recovery methods —— inverse Stokes formula with 2DFFT and along-track vertical deflection with 1D Hilbert Transform, are used in this section. The second method is developed independently by author on the basis of the Laplace's equation in Cartesian system.

主要利用三颗卫星测高数据——Geosat/GM、ERS-1和Topex/Poseidon，采用了两种不同的重力异常恢复技术——Stokes公式逆运算+FFT处理和改进后的沿轨迹垂线偏差恢复法，构造了两个区域大小不同、分辨率不同(30'×30'和2'×2')但精度大体相同(10mGal)的重力异常——IGG97和IGG99S。

He compressed between 2 fingers the flesh circumjacent to a cicatrice in the left infracostal region below the diaphragm resulting from a sting inflicted 2 weeks and 3 days previously (23 May 1904) by a bee.

Taking the plate tectonics as leading theories, combining outcrop, seismic techniques, drilling and logging datum, inter-verifing manifold researching methods, The paper has amply researched the region. discussed the coupling relation of basin-mountain and the geodynamics system; analyzed geologic tectonic characteristics of the basin; confirmed superposed alteration in Mesozoic of the basin; recompartmentalized tectonic units of the researching region and the basin; studied the tectonic evolution of the basin since Mesozoic; ascertained four large tectonic layers and five tectonic evolution process stages in different ways of formation and tectonic alteration; established different tectonic stages、compages、models and sedimentary filled processes, based on the organic geochemistry and oil-gas geologic characteristics in middle Cenozoic of the basin, the conclusions have been summarized in the paper, such as:The primary source rock in lower Permian and subordinate source rock in upper Triassic are developed in the region with better quality, and secondary hydrocarbon is possible; The bearing system which is comparted by three large tectonic layers and two unconformity surfaces formed in Palaeozoic、upper Palaeozoic to Triassic and Cenozoic developing in the region, compounded with reservoirs of different lithology is developed in the region, while the property of tectonic fracture reservoir is better; Based on the analyzing petroleum accumulation elements and preserving conditions, the deep depressing belt in the north of Luoyang depression、Shiling-Yiyang folded fault belt in Yiyang depression and wide anticline belt in Yichuan depression are advantageous petroliferous region, Zhaizhen anticline in Luoyang depression and Shimen wide anticline on footwall of overthrust in Yichuan depression are optimum tectonic traps.

本文以板块构造理论为指导思想，采用露头区野外地质与盆地地震、钻井、测井资料密切结合，多种测试方法互检的研究方法，探讨了盆山耦合关系及其所控制的地球动力学系统；分析了研究区域和盆地地质结构构造特征，确定了中生代盆地的叠合改造性质，并重新划分区域构造单元和盆地构造单元，深入研究了洛阳—伊川盆地自中生代以来的构造演化；确定了成盆作用和构造改造作用的四大构造层和五期不同方式、方向的构造演化过程；建立了不同构造阶段的构造组合和样式及与构造相关的沉积充填过程；在此基础上通过多种有机地球化学指标，研究盆地中新生代油气地质特征，认为本区发育下二叠统区域主力烃源岩、上三叠统区域非主力烃源岩，两套烃源岩质量均较好，并具备二次生烃条件；认为本区发育古生界、上古生界—三叠系和新生界三大构造层、两个不整合界面分隔、不同岩性储集层叠置组合和构造裂隙型储集层的复式储集体系，其中构造裂隙型储集层储集性能较好；依据油气成藏条件和保存条件分析，认为洛阳凹陷北部深凹带、宜阳凹陷内石陵—宜阳褶断带以及伊川凹陷伊川宽阔背斜带为较有利含油气区，有利的构造圈闭是洛阳凹陷翟镇背斜和伊川凹陷的石门逆冲断层下盘的宽缓背斜

Mr. Compton agrees that China and India push it too far sometimes.

Compton先生在中国和印度投资的过程中发现，那里的很多孩子各科都比他两个10来岁的女儿要领先两到三年，特别是数学和科学。

And on the international side, when we talked about the exchange rate, it's two money, two currency's relationship, when dollar continue to fall, how you can keep rate stable and if you do the big step, you still don't know, if you can get the equilibrant or not.

站在国际的角度来看，我们所探讨的汇率问题，是两种币种间的关系，当美元不断贬值时，你怎样保持汇率稳定？即使你做出调整汇率的重大举措，也还是无法肯定，两方能否达到均衡。可能它暂时均衡了，但过了三四个月或半年，美元又贬值了。

We will find that Chinese classical literature is the Beginning of the origins of Chinese kongfu, in china,kongfu learned from two aspects;one is culture another is body. gunslinging stick with poetry.our early ancestors were as important is the cultural accomplishment of two aspects.

稍加留意，就会发现，中国武术的滥觞，正是中国古典文学的发轫；文事与武备至少在两三千年以前，就像是一对孪生兄弟携手而行；舞枪弄棒与吟诗作赋，很早就是被我们先民所看重的文化修养的两个方面。

According to the clear water experiment, aeration performance of the new equipment is good with high total oxygen transfer coefficient and oxygen utilization ratio.

曝气设备的动力效率在叶轮转速为120rpm～150rpm时取得最大值，此时氧利用率和充氧能力也具有较高值。

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。
