石油微观渗流数值模拟实验

应用基于骨架隐曲面造型技术，构造了一种抽象的孔隙空间模型，在此基础上运用系统模拟技术开发了一个石油微观运移数值模拟实验平台，用于模拟和展示石油在饱含水孔隙介质中的运移过程，并验证了以浮力为主要运移动力的动力学模型的适用性。     

转动惯量与惯量积二者平行轴定理的统一处理

将相对于刚体内某定点O的惯量张量分解为两部分:一为相对于刚体质心C*的惯量张量;另一为相对于O点的惯量张量,但假定刚体的所有质量都集中在C*点。如此的分解,能使转动惯量平行轴定理或惯量积平行轴定理均极其便于表述。这样获得的两个定理中,前者已熟知后者尚陌生,且前者只不过是后者的特例。通过惯量张量本身即可统一处理此二定理,而且它们的表达式将全部概括在单个公式之中。

Structural Changes of Water Molecules Upon the Reduction of Quinones in The Reaction Center from Rhodobactery Sphaeroides

1 Results The photosynthetic bacterial reaction center (RC) is a membrane protein complex.The RC is composed of three protein subunits and redox components such as bacteriochlorophylls, bacteriopheophytins,and quinones.The RC performs the photochemical electron transfer from the bacteriochlorophyll dimer through a series of electron donor and acceptor molecules to a secondary quinone,QB.QB accepts electrons from a primary quinone,QA,in two sequential electron transfer reactions.The second electron trans...

Pathways for oxidative fuel provision to working muscles: Ecological consequences of maximal supply limitations

The study of metabolic fuel provision and its regulation has reached an exciting stage where specific molecular events can be correlated with parameters of the organism's ecology. This paper examines substrate supply pathways from storage sites to locomotory muscle mitochondria and discusses ecological implications of the limits for maximal flux through these pathways. The relative importance of the different oxidative fuels is shown to depend on aerobic capacity. Very aerobic, endurance-adapted animals such as long distance migrants favor the use of lipids and intramuscular fuels over carbohydrates and circulatory fuels. The hypothesis of functional co-adaptation between oxygen and metabolic fuel supply systems allows us to predict that the capacity of several biochemical processes should be scaled with maximal oxygen consumption. Key enzymes, transmembrane transporter proteins, glucose precursor supply and soluble fatty acid transport proteins must all be geared to support higher maximal glucose and fatty acid fluxes in aerobic than in sedentary species.     

人性·人本·人化--人本管理的实质及其管理实现

管理理论的建构常常以某种人性假设为前提.对复杂人性本质的不同推定,决定着管理科学理论的不同走向.人本管理是一种有别于其他诸如"物本管理"、"资本管理"、"能本管理"等的管理理论,其不同之处或者说其进步性就在于它谋求对人的理解,即试图在对人性的种种假设中探寻"人"与人之"本"的内在逻辑,以建立一种"人为"与"为人"的柔性的管理规约.在我国特有的管理语境中,人本管理的本质与实现的理解是有其独特性的.在管理实践中,人不仅仅是手段,人本身也是目的.
