Black mudstone and oil shale appeared on the uplift, while, stratum rich in gritstone detected in the Sunken area, as the most important characters, become difficult to research.

隆起区构造单元富泥质沉积，凹陷构造单元富砂质沉积，成为研究区孔二段的主要特征之一，也成为研究的难点。

Relative hydraulic conductivity is first evaluated cell boundaries by using full upstream weighting, the arithmetric mean, or the geometic mean of values from adjacent cells. Saturated hydraulic conductivites are evaluated at cell boundaries by using distance—weighted harmonic mean.

首次采用分散平均方法估算水力传导率，即运用上风权重法来估算单元边界的相对水力传导率，运用距离权重调和平均法来估算单元边界的饱和水力传导率。

This is because heteroatom species have been fixed in the framework of the zeolite primary units when the seed solution is prepared and with the self-assembly of the zeolite primary units surrounding the surfactant, heteroatom species are directly introduced into the mesostructure.

这是因为在制备沸石导向剂的过程中，杂原子被固定在沸石的微结构单元中，当沸石导向剂与表面活性剂通过自组装过程形成介孔分子筛时，杂原子随沸石的微结构单元一起进入了产物的骨架当中。

For distinctly understanding the mutual influence between the structural units, a series of compounds from five and six-membered C-N heterocycle substituting the tetrazine ring are designed. These several types of compounds are studied by means of the quantum chemistry calcualtions and discussed the influence of the structural units upon the main performance (heat of formation, density, velocity and pressure of detonation) and found out the best combination of performance.

为了更清楚的了解结构单元之间的相互影响，设计了六元氮杂环和五元氮杂环取代1，2，4，5-四嗪得到了一系列化合物，采用量子化学计算方法对它们进行了详细的理论研究，讨论了各种氮杂环的改变对四嗪类化合物性能(包括生成热、密度以及爆速和爆压等)的影响，并找出爆轰性能较好的结构单元组合。

A new thought line of reservoir characterization is put forward based on the combination of the high resolution sequence stratigraphy,the architectural element and flow unit analysis method.It integrates the static geological body with the dynamic developing process,the reservoir heterogenesis with oil and water distribution from macro scale to micro scale.

应用高分辨率层序地层、结构单元及流动单元分析的三位一体理论指导储集层的表征建模，从而形成由宏观到微观、静态地质实体与动态开发过程、储集层非均质性与油水分布及流动规律相结合的体系是储集层精细描述的新思路。

Combined with the new process and new products, we have developed their characteristic equations and models, especially for hollow; heteromorphism and composite fibers.

结合新工艺和新产品的开发，本文推导了高速纺丝、热管纺丝、热辊纺丝等工艺的特征单元方程及中空、异形、复合纺丝等新品种的特征单元方程，着重推导了圆形纤维、中空纤维、三叶异形纤维、皮芯复合纺丝的分层结构模型及分块模型，并对高速纺丝及中空纤维的不对称冷却结构进行了系统的数学模拟。

By constructing a sphere hexagonal grid system based on the Truncated Icosahedrons Projection, this paper focuses on the study of the address coding mechanism of the sphere hexagonal grids, including the hierarchy coding schemes, the study of the positional relations among the grid units and the mutual conversion between the address codes of the grid units and the geographical coordinates.

本文通过构建基于截顶正二十面体投影的球面六边形网格系统，对球面六边形网格的地址编码机制进行了重点研究，包括网格的层次编码方案、网格单元位置关系研究和网格单元地址码与地理坐标之间的相互转换。

We can now use tetrahedron and hexahedron elements in three-dimensional stress analysis.

我们现在在三维应力分析中采用四面体单元和六面体单元。

In this paper,strain and stiffness matrix of isoparametric element with eight nodes and hexahedron are derived in detail.

推导了八节点六面体等参单元的应变矩阵、刚度矩阵，对该单元的位移解收敛性和畸变敏感性进行了分析。

The calculation accuracy and the calculation efficiency of hexahedron mesh generated by author are higher than tetrahedron element.

所剖分的六面体单元的－计算精度和计算效率都高于四面体单元。

I am accused of being overreligious," she said in her quiet, frank manner,"but that does not prevent me thinking the children very cruel who obstinately commit such suicide.""

客人们在卡罗利娜·埃凯家里，举止就文雅一些，因为卡罗利娜的母亲治家很严厉。

Designed by French fashion house Herm è s, this elegant uniform was manufactured in our home, Hong Kong, and was the first without a hat.

由著名品牌 Herm è s 设计，这件高贵的制服是香港本土制造，是我们第一套不配帽子的制服。
