Nuclear Magnetic Resonance Logging has been widely used in determining porosity of formation.

核磁共振测井是确定地层孔隙度的有效方法，已经得到广泛应用。

The effect of the size of particulates and pressing pressure on porosity ratio has been studied.

对 Al2 O3颗粒预制体的气孔率测定方法进行了探讨，研究了颗粒粒度与压制压力对气孔率的影响。

Further, The parameters, such as the diameter of expansion chamber, flow velocity, porosity of the open cell and the length of the extended tube, are also investigated.

此外，文中亦分别探讨膨胀管直径、管中流速、槽孔开孔率、入口段延伸管长度对消音器性能之影响。

In this paper, the mechanisms of the generation, migration and production for coal seam gas are researched and the geological model for coal seam gas reservoir simulation is presented, according to the theories and methods of coal seam gas geology, petroleum geology and dynamic of fluids through porous media. A three-dimensional, dual-porosity, two-phase, pseudo-steady, non-equilibrium sorption mathematical model is established with the help of petroleum reservoir numerical simulation method. After that, this complex mathematical mode is approximated and solved by finite-difference and fully implicit methods. Coal Seam Gas Reservoir Simulation software in 1. 0 version (CSGRS 1. 0) with Chinese interface of pre-and post-processing function is developed.

本文应用煤层气地质学、石油天然气地质学和渗流力学等学科的理论和方法，研究了煤储层中煤层气的生成、储集、运移和产出机理，概化出了煤层气储层模拟的地质模型；以油气藏数值模拟和数值计算方法为工具，建立了描述三维、双孔隙、非平衡吸附、拟稳态条件下气-水两相流体混相运移规律的煤层气储层模拟的数学模型；详细推导出了该数学模型的全隐式求解方法；并借助计算机技术开发了具有中文操作界面的煤层气储层数值模拟软件CSGRS 1.0，实现了这一复杂数学模型的数值求解。

However,it is the dissipa-tive mechanism,i.e.the mechanism of energy localization that attracts one′sattention for the problem of shock initiation.Since the test result of shock initia-tion about fine-grain explosive charge does not support hot spot ignition model,the author of this dissertation advances that the mechanism of energy localiza-tion is coincident with phonon-fracton crossover of fractal network for ultra-fine-grained charge and,moreover,analyzes the relation between shock sensi-tivity and porosity,which is consistent with shock Hugoniot curve for porousmaterials.

由于超细颗粒压装炸药的冲击起爆实验不支持热点点火模型，为此、本文提出对于单晶颗粒半径为微米以下量级的药床，冲击起爆的能量局域化机制与分形网络中弱局域化声子向强局域化分形子的渡越对应，并且根据这一机制分析了超细颗粒药床的冲击感度和孔隙度的关系，结果与多孔物质冲击压缩的P-V图吻合。

The labia have now been sutured together almost completely.The drains and the Foley catheter come out at the top.

此刻阴唇已经几乎完全的缝在一起了，排除多余淤血体液的管子和Foley导管从顶端冒出来。

To get the business done, I suggest we split the difference in price.

为了做成这笔生意，我建议我们在价格上大家各让一半。
