就油气勘探而言，盆地实际上是指联片分布的沉积岩体。

The atmosphere in areas in which hydrogen gas may be vented and might collect should be tested with a portable or continuous flammable gas analyzer.

用便携式或连续可燃气体分析仪来监测特定区域的空气，这些区域包括氢气排放口和氢容易积聚的地方。

The atmosphere in areas in which carbon dioxide gas may be vented and collect should be tested with a portable or continuous monitoring carbon dioxide gas analyzer to ensure ventilation is adequate.

The outer layers form a convection zone where the gas material transports energy primarily through physical displacement of the gas.

外层形成对流区的天然气输送能源材料主要是通过物理位移的天然气。

For gas flow past cylinder, the characters of flow field in different Mach number and Knudsen number condition were investigated, and especially for low Knudsen number cases, the results were compared with calculating results of Euler's equation. It showed that they are correspondent by comparing the characters of bow shock and wake. The convergence rates of different high resolution and implicit schemes were also investigated. The convergence behavior of the implicit WENO scheme developed in this paper is better than others. For gas flow past NACA 0012 airfoil, the calculating results were compared with results of experiment. It showed that the results of WENO scheme are of higher accuracy for the case with angle of attack.

在圆柱流场时，我们探讨不同马赫数且不同纽森数时的流场特性，并在低纽森数时，与那维尔-史托克方程式的计算结果比较，我们比较了弓形震波及尾流附近的特性，其结果是相当符合的，同时我们也比较不同高解析隐式算则的收敛历程，从收敛历程图可得到，本文发展出来的隐式WENO算则有较佳的收敛效果；在NACA 0012翼形的流场中，我们将与实验结果做比较，发现利用WENO算则计算的结果，对於具有攻角的流场，亦有相当高的准确度。

D gas field is a structural-lithological reservoir. The main gas formation is marine shoreface sandstone dam and shoreface beach sand. The reservoir has serious anisotropy. This mainly shows the coombe on the surface and the thin interlayer in reservoir.

D气田为构造－岩性油气藏，主力气层为海相临滨砂坝和临滨滩砂，储集层非均质性严重，主要表现为平面上的冲沟和储层内部厚度较薄的隔夹层。

After analyzing dynamics characteristic, flow pattern of gas flow in the cortile building, and the high, form factor,opening area of the cortile, then comes out with corresponding flue gas control methods such as region separation, vacuum extraction , space-filling.

之后在详细分析中庭建筑烟气流动的动力学特性、流动规律及中庭的高度、形状系数、开口面积等影响因素的基础上，提出了区域分隔法、负压排烟法、空间填充法等相应的烟气控制方法。

It was found that count rate reduces while gas flowing rate increases.This fact can be explained by the lasting time of gas in the scintillation chamber.

发现计数率随气体流量的升高而降低，并用氡气在闪烁室中的通过时间予以解释。

It is verified that the most dangerous operation condition of crankshaft is not happening at the upper point of gas re-inlet or while the crankpin is bearing a maximum force of gas.

目前已有很多文献运用有限元法得到圆角、油孔等应力集中部位的精确应力值，以此分析曲轴的静强度，但是它们都存在一些
