基于微观渗流机理的宏观油藏数值模拟研究

处于高含水开发期油藏的剩余油分布主要受流体性质和岩石孔隙结构的影响，而经典数值模拟并没有考虑微观孔喉特征的影响。为此建立了描述微观孔喉特征的地层孔隙网络模型，并对构成网络的基本连线单元进行改进，使网络模型能更细致地描述油水分布特征和水驱油微观机理。利用逾渗理论计算了基于微观渗流机理的相对渗透率曲线，并将其应用到经典数值模拟计算中，实现了微观渗流机理与宏观数值模拟计算的结合。实例分析表明，利用该数值模拟计算方法得到的基于微观特征的剩余油分布更符合地下实际流体分布，其结果可为调剖堵水、化学驱提供技术参数。     

人的全面发展观与学生党支部建设

“人的全面发展”观是马克思主义人学理论中的一个基本观点。全面发展的人是社会现代化的构成和目标，促进人的全面发展是社会主义现代化事业的目标和任务。高校学生党支部要按照人的全面发展的观点，调整党支部的工作思路，改进党支部的内部管理，形成充满活力的运行机制，使学生党支部真正成为高校学生中党的工作的主阵地。     

一阶线性非齐次微分方程求解方法的讨论和一个简化的求解方法

本文证明了一阶线性非齐次微分方程y＇+P(x)·y=f(x)三个求解方法:参数变易法、积分公式、积分因子法之间的等同关系.从参数变易法中引出一个简化的积分公式.事实上此公式恰是对用参数变易法解高阶线性非齐次微分方程时对n=1的拓广.最后以实例验证此公式的简易.

Common Molecular Mechanisms of Mammary Gland Development and Breast Cancer

During its lifetime, the mammary gland undergoes many phases of development and differentiation. Much of this occurs during puberty, when the ductal epithelium expands by branching morphogenesis, invading the surrounding fat pad to form an organised mammary tree. Throughout its existence, the epithelium will go through several cycles of proliferation and cell death during pregnancy, lactation and involution. Many of the signalling mechanisms which control the initial invasion of the fat pad by the epithelium, and regulate its continuing plasticity, can be harnessed or corrupted by tumour cells in order to support their aberrant growth and progression towards invasion. This is true not just for the epithelial cells themselves but also for cells in the surrounding microenvironment, including fibroblasts, macrophages and adipocytes. This review examines the complex web of signalling and adhesion interactions controlling branching morphogenesis, and how their alteration can promote malignancy. Current in vivo and in vitro mammary gland models are also discussed. (Part of a Multi-author Review)

Development of Full Automatic External Welding Machine for Annular Welds of Pipeline

To meet the demands of rapid development of pipeline constructions in China, a complete set of full automatic external welding machine for annular welds of pipeline and welding procedure have been developed thereof. The system has been applied in the “West-East Pipeline Project” and its performance is proven. With this welding machine the welding parameters can be either preset before or adjusted in real time during the welding process, which avoids the blemishes of same type domestic and international products. Thus it is best propitious to in-situ construction conditions and workers‘ technical level in China. In this article the development of mechanical and control systems of this product is introduced and typical welding procedure parameters are provided.
