层叠

Standing in front of these oil paintings of Feng Jincao,as if we were flying through the time tunnel. Whirring wind slipped by, clouds changed their shapes quickly, and continual changing views blurred and danced before our eyes. We trace the jumping-of point of human being in a diverse direction of time's growth. Those brilliant rays of history frozen in memory reflect on our dress, and the root of our culture shows loving care for modern people's sprit and life by Feng's painting.

前言 站在冯劲草的油画作品面前，我们仿佛正在穿越时空隧道，耳边是呼呼的风声，眼前是千层万叠的烟云和不断模糊变幻的视野，我们逆向时间轴的速度要追回人类逝去的起点，那些凝结在记忆里的历史光芒斑驳地映在我们的衣杉上，我们的文化之根正通过冯劲草特殊的油画表达方式，关怀着当代人的精神和生活。

On the base of large quantitative test, using coal petrography and organic geochemical data, the source of oil and gas in the coal-measures is analyzed. And it is concluded that the area's Yan'an group coal-bed has a low potential of oil production, and the oil and gas contained in the coal-measures and superjacent strata comes from underlying Upper Triassic Yanchang group strata. After a series of parameters of coal seam and surrounding rocks are tested, gas formation, storage, preservation, permeability of the coal-rock seam are analyzed and evaluated.

本文在大量测试工作基础上，利用煤岩学与有机地球化学资料，分析了煤系油气的来源，认为本区延安组煤系煤层生油潜力差，煤系及其上覆地层所含油气为下伏上三叠统延长组源岩所生，油气主要通过迭置的砂体、不整合面、构造裂缝等自下向上运移进入煤系；通过对煤层及围岩一系列物性参数的测试，分析与评价了煤岩层的生、储、盖、渗性能与可抽放性，得出主采4_(-2)号煤层属中等储集、低渗透层，围岩封闭性差，渗透性高，煤层瓦斯含量低，而顶板砂岩瓦斯含量高，为采面瓦斯涌出的主要来源。

This thesis studies each structural layer's feature:(1) structural layer of basement:it is a Paleozoic folded basement,whose tectonic deformation and magma intrusion is fiercely,and it is affected by the early Hercynian tectonic movement and related to the underthrust and closure (C1) of Zhungaer ocean basin and the areal pressing of continents (C2-3);(2) structural layer of Permian:due to the regional extending and fault depression role in mid-Hercynian,it occurred to the combinations of structure and magma in Santanghu basin and it's periphery area,such as A-granite's stock,batholiths and diabase's dike.

二叠系构造层：受中海西区域性伸展断陷作用的影响，盆地及其周缘地区发育与伸展构造有关的构造-岩浆组合，如呈岩株、岩基状侵位的A型花岗岩以及呈岩墙状侵位的辉绿岩等。

Then,two geologic models were designed,including layered model and interface undulated model,which were used to carry out post-stack reverse time migration by spectral element method on forward modeling results in anisotropic and isotropic medium.

设计了层状和界面起伏两个地质模型，分别在各向异性介质和各向同性介质条件下对正演模拟结果进行了谱元法叠后逆时偏移。

Chapter Four discusses the aesthetic and rhetoric values of the techniques of metonymy, simile, analogue, inversion, couplet, metaphor etc., in the versicle.

第四章〈小诗的修辞之美〉以修辞为经，美学为纬，爬梳小诗呈现在类叠、排比、映衬、层递、倒装等五种主要形式修辞中的美感。

Weak formulation of mixed state equations including boundary conditions are presented in a cylindrical coordinate system by introducing Hellinger_Reissner variational principle.

从Hellinger_Reissner变分原理出发，在柱坐标系中，导出圆柱壳的弱形式混合状态方程和边界条件，联用状态空间法给出叠层柱壳的解析解，此法使得求解该类问题的形式得以扩大和统一。

Temperature and, unlike the zener diode, the multilayer varistors have the added advantage that, when operated up to

与齐纳二极管不同，叠层片式压敏电阻器具有低漏电流特性，在最高工作温度下，漏电流不超过500μA。

The large-scale volcanic activities during fault-depression period and the strong geothermal field resulted from the huge thick and stable sediment during depression period sped up the transformation of hydrocarbon source rock and resulted in the formation of large amount of abiogenetic gas.

断陷期大规模火山活动，坳陷期巨厚而又稳定的沉积产生的强地温场加速了烃源岩的转化，并有无机成因气大量产生，营城组沉积时数万平方千米范围的火山喷发，形成了爆发相和喷溢相叠合的有利相带，发育了具有孔隙和裂缝双重介质中酸性火山岩储集体，相对独立的火山岩体在巨厚的沉积盖层下形成独特的圈闭类型。

Blade assembly is cured at 250℉ in a machined metal mold. After curing, the blade is trimmed, the Polyurethane leading-edge erosion strip is applied, and the blade is finished and balanced. Tungsten leading-edge weights in the outboard 50% of the blade provide aeromechanical stability, and tungsten tip

主旋翼翼梁以石墨、玻璃纤维及环氧树脂模合而成，诺美克思蜂巢结构的翼后缘夹心黏附於翼梁及旋翼后缘强化结构上，组成后在华氏250度的预热金属模上包里玻璃纤维叠层，经过修裁，加上聚配胺抗腐蚀片后才告制作完成。

This paper employs clay stone analysis to Permian-Triassic boundary strata from three deep water sections, Duanshan, Nashui and Liuqiao, located in Guangxi and Guizhou region, southwestern China. The result shows that clay stones from the three localities are composed of illite-montmorillonite mixed layer, montmorillonite and kaolinglite. There are rock fragments such as bipyramid quartz and zircon which are related to volcanic process found in all the sections except in Nashui section.

对贵州断杉、纳水以及广西柳桥3条深水相剖面上的二叠系－三叠系界线附近黏土岩的研究结果表明，在断杉、柳桥剖面黏土岩中的私土矿物主要由伊－蒙混层、蒙脱石和高岭石组成，碎屑物质中存在六方双锥石英、锆石等与火山活动有关的矿物；在纳水剖面黏土岩中未发现与火山活动有关的迹象。

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。
