The results indicate that there are 8 stable conformers for D4G in gas phase. The conformer d4g-2 is the most stable form of all conformations in gas phase.

结果表明，孤立的D4G分子在气相中存在8种稳定构象，其中构象d4g-2是所有构象中最稳定的，气相中D4G主要以d4g-2存在。

As for oil and gas exploration,basin means connectedly distributed sedimentary rock mass;as for the reserves,about 500/0 of oil reserves and 700/0 of gas reserves are in reformed basins.

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.

应该用移动或连续的二氧化碳监测分析仪来测试可能排出或积累二氧化碳气体的区域，以保证通风是充分的。

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。
