沉积微相约束条件下的随机地质建模方法及应用研究

以地质建模为主要研究对象,根据油田开发地质研究需要完善的方法技术,以建模方法研究为基础,进行了沉积微相约束地质建模综合研究.在分析目前国内外研究现状的基础上,针对我国开发地质研究工作的特点,提出根据测井解释成果,应用随机模拟的方法定量地开展沉积微相研究.应用沉积微相研究成果约束测井储层参数的分布,形成油藏数值模拟研究所需要的准确的储层三维地质模型,解决了常规油田开发地质研究过程中沉积相研究成果与储层参数分布无法有效结合的缺陷.应用与该方法相适应的IRMS软件成功实现了山东胜利油区孤东油田第七开发区西部上第三系馆陶组油藏精确的沉积微相模型,由此微相约束形成的油藏储层三维地质模型数据体直接应用于油藏数值模拟研究,应用效果及现场实施的效果良好.     

引文国际化对论文被引的影响研究

[目的/意义]在学术交流日趋国际化的背景下,本文拟探索引文国际化与被引量之间的关系,力图回答良好的国际视野是否有助于提升论文的学术影响力这一学界普遍关注的问题。[研究设计/方法]以社会科学为研究对象,选取管理学、图书情报学和新闻传播学的181,406篇CSSCI论文为研究样本,采用相关分析、非参数检验与回归分析的方法研究引用外文期刊论文的数量、学术质量、学科领域、时效性对论文被引量的影响。[结论/发现]在控制了文献类型、期刊声誉等若干可能影响论文被引量的因素后,发现样本论文的引文国际化水平对其被引量具有显著的正向影响。具体而言,引用外文期刊论文的数量越多、平均学术质量越高、学科专属度越高、平均时效性越强的论文具有更高的被引量。[创新/价值]证实了国际视野有助于提升中文社科论文的学术影响力,并提出了有针对性的建议。     

Lipids changes in liver cancer

Liver is one of the most important organs in energy metabolism. Most plasma apolipoproteins and endogenous lipids and lipoproteins are synthesized in the liver. It depends on the integrity of liver cellular function, which ensures homeostasis of lipid and lipoprotein metabolism. When liver cancer occurs, these processes are impaired and the plasma lipid and lipoprotein patterns may be changed. Liver cancer is the fifth common malignant tumor worldwide, and is closely related to the infections of hepatitis B virus （HBV） and hepatitis C virus （HCV）. HBV and HCV infections are quite common in China and other Southeast Asian countries. In addition, liver cancer is often followed by a procession of chronic hepatitis or cirrhosis, so that hepatic function is damaged obviously on these bases, which may significantly influence lipid and lipoprotein metabolism in vivo. In this review we summarize the clinical significance of lipid and lipoprotein metabolism under liver cancer.     

Novel distribution pattern of fibrinolytic components in rabbit tissues extract： a preliminary study

Objective: The purpose of this work was to investigate the distribution pattern of fibrinolytic factors and their inhibitors in rabbit tissues. Methods: The components of the fibrinolytic system in extracts from a variety of rabbit tissues, including tissue plasminogen activator (tPA), plasminogen activator inhibitor-1 (PAI-1), plasminogen (Plg), plasmin (Pl) and α2 plasmin inhibitor (α2PI), were determined by colorimetric assay. Results: The tissue extracts in renal, small intestine, lung, brain and spleen demonstrated strong fibrinolytic function, in which high activity of tPA, Plg and Pl was manifested; whereas in skeletal muscle, tongue and stomach, higher activity of PAI-1 and α2PI showed obviously. Also excellent linear correlations were found between levels of tPA and PAI-1, Pl and α2PI, Plg and Pl. In related tissues, renal cortex and renal marrow showed distinctly higher activity of tPA and lower activity of PAI-1, with the levels of Plg and Pl in renal cortex being higher than those in renal marrow, where the α2PI level was higher than that in renal cortex. Similarly, the levels of tPA, Plg and Pl in small intestine were higher than those in large intestine, but with respect to PAI-1 and α2PI, the matter was reverse. In addition, the fibrinolytic activity in muscle tissue was lower, however, the levels of tPA, Plg, and Pl in cardiac muscle were obviously higher than those in skeletal muscles, and the levels of PAI-1 and α2PI were significantly lower than those in skeletal muscle. Conclusion: Our data demonstrate that a remarkable difference of the fibrinolytic patterns exists in rabbit tissues, which has probable profound significance in understanding the relationship between the function of haemostasis or thrombosis and the physiologic function in tissues.     

竞技健美操运动的核心力量训练

用点差法巧解中点弦问题

点差法在解决与中点有关的问题时确实很有用。它通过“设点”、“作差”两个步骤。就产生了弦的中点和弦所在直线的斜率,巧妙地避免了解方程组求交点的复杂运算,使问题轻松获解。与常规解法相比,其优越性显而易见。     

构建虚拟社会中的大学生伦理道德培育体系

作为一种新型的社会形态,虚拟社会对大学生的伦理道德产生了影响。构建虚拟社会中的大学生伦理道德培育体系,既顺应了社会发展之要求,又保证了大学教育之质量。构建虚拟社会中的大学生伦理道德培育应以大学生这一主体为核心,坚持虚拟与现实、自律与他律、绝对与相对、权利与义务相结合等原则,围绕基本伦理道德、道德行为规范、社会主义核心价值体系、科学文化及法律法规等内容,从建立健全相关的法律法规、合理运用科技手段、提高大学生的道德素养三个方面来构建虚拟社会中的大学生伦理道德培育体系。     

中国文化特色词汇音译研究与中国文化传播的反思

随着国际交流的不断加深及各国之间文化交流不断加快,翻译界对文化翻译的重视程度也越来越高,对中国文化特色词汇的翻译研究更加深入。音译作为一种并不新颖的翻译方法,却在文化特色词汇的翻译过程中发挥着十分重要的作用,并受到越来越多的关注。在汉译英翻译过程中,对于极具中国特色的几类文化词汇采用音译翻译,能够避免文化误读,增进中国文化在异域文化中的认知和认同,最终达到最佳效果的文化传播和交流,引起人们对中国文化的全新考量。
