该系统最主要的特点是气层均具有低压异常，而上部层位水层具有正常地层压力，具有气在下水在上、气水倒置的典型深盆气藏特点。

At first, numerical simulation are made on the temporal developing gas-phase mixing layer where the convective mach number is in the region of subsonic(0.5) and transonic(0.8). For the temporal problem where Mc is 0.5, researches where the computational field contains different numbers of initial disturbances(so-called n period problem) are made respectively, and vortex's types of evolution in mixing layer including different numbers of initial disturbances are investigated; For the temporal problem where Mc is 0.8, the distinct shock let structure is obtained, and its mechanism is analyzed at the same time.

文中首先对对流马赫数为亚声速(0.5)、跨声速(0.8)的时间发展单气相混合层作了数值研究，对Mc为亚声速单气相时间发展混合层，分别研究了计算域包含不同数目的初始扰动周期问题，考查了不同周期数的混合层中涡的不同演化方式；对Mc为跨声速的单气相时间发展混合层，得到了清晰的小激波结构，同时分析了小激波的形成机理。

The results show that, both normal and tangential blowing are effective means of flow control, the influence of blowing on the cone-cylinder is strongest, followed by the influence of blowing on the elliptic forebody and on chine forebody.

实验表明，法向吹气和喷管切向吹气都是有效的控制手段，吹气对其中圆锥截面模型的影响最大，椭圆截面模型次之，对带棱截面模型影响最小。

It is revealed that a certain amount of excessive formamide is favorable for preparation of the aerogel with high porosity, while more excessive glycol can deteriorate the formation of nano-porous SiO2 aerogel network. Additionally, the pH value of the reaction system has a strong impact on the microstructure and properties of prepared SiO2 aerogel.

研究发现：微过量的甲酰胺，有利于高孔隙率气凝胶的合成；过量的乙二醇的引入不利于低密度气凝胶的形成；pH值对合成气凝胶的性质也有较大的影响。

The determination of gas storage pressure in high-pressure tube bank and the calculation of actual gas storage volume are analyzed. The metal consumption of high-pressure pipeline is compared with that of spherical gasholder.

分析了高压管道储气方式储气压力的确定、实际储气体积的计算，进行了高压管道与球罐的金属消耗比较。

The progammable pipeline, especially nbspvacuum exhaust port hithermost a rubber tube was most likely to result in a flat suction nbspvacuum gas pipeline damage that prevents the rubber hose is an effective way of a flat is to install rubber tube a few root and pneumatic tube diameter equal to the springs.

晒版机惯路，尤其是真不满泵抽气口最挨近的一段橡胶惯最便当被真不满泵呼凹变成气路惯道毁坏，制止橡胶惯被呼凹的灵验方法是不兵橡胶惯边安设上几不梢与气路惯屈径不等的弹簧。

After finding the reason which causes the sands to sink, weGived a improving measure, which is opening some litter holes at the pipe,similarly thepulse immixture the typical,in the subsequent experiment, the pulse was proved that it isbetter than the typical on many performances, include an important performance—watertlow rate.

在分析沙粒下降原因的基础上，提出了改进措施，即在提升管上钻若干个小孔，类似将常规气提装置的原理应用过来，在随后的实验中，证实了改进后的气提装置在诸多性能上要优于常规气提，包括水流量这个重要的参数。

First, from the macro view of gaswater distribution and movement law, the formation mechanisms of edge water, inlayer water and interlayer water, as well as the three basic models of water breakthrough in gas wells were analyzed. Then from the microscopic angle, this paper studied the reservoir pore structure and rock wettability of loose sandstone gas reservoir, and analyzed their control effect on gas reservoir's original gaswater distribution.

首先从宏观气水分布及气水运动规律的角度出发，分析了边水、层内水、层间水的形成机理和气井见水的3种基本模式；然后从微观角度，对疏松砂岩气藏的储层孔隙结构及岩石润湿性进行了研究，分析其对气藏原始气水分布的控制作用。

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。
