研究地质

On the basis of previous research and the authors' field investigations,it is thought that the complex geological structures,strong crust movements and rivers erosions,frequent earthquakes,abundant loose deposits,favorable geomorphology,well-developed modern glaciers and plentiful precipitation are the principal causes of triggering frequent mudflows in the study area.

根据前人的成果以及作者的实地调查，认为复杂的地质构造、强烈的地壳运动和河流切割、频繁的地震、丰富的松散堆积物、有利的地形地貌、现代冰川以及丰沛的降雨是研究区泥石流灾害频繁发生的主要原因。

For its special conditions of production, fullerene is hardly yielded through the process of the common earth environment and dynamic geology. The first presence of fullerene in Shungite, Russia in 1992 aroused the interest of studying natural fullerene.

富勒烯的形成条件特殊，普通的地球环境和地质过程不利于富勒烯的生成。1992年天然富勒烯在俄罗斯前寒武纪地层桑加岩中被发现，引起了人们对天然富勒烯研究的兴趣。

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。

The discrete-element modeling is a new dynamic modeling method in structural geology and geophysics research. The authors built a discrete element model to simulate the evolution of the fault system in active salt domes. Results show that the fault system undergoes three stages: symmetric deformation stage, asymmetric deformation stage, and complete fracture stage.

离散元模拟是构造地质地球物理研究中一种新的动力学模拟方法，作者通过构建离散元模型，模拟了主动底辟盐构造断裂系统的演化过程，结果表明，该断裂系统的发育主要经历了对称变形、不对称变形、整体破裂三个阶段。
