作者 陈婷 徐建培 《商业时代》 北大核心 2005年第26期63-64,共2页
外资介入中国上市公司的并购活动是资本市场发展的必然,其并购模式在一定程度上影响着并购重组上市公司的效果。结合我国宏观政策的倾向和外资并购中存在的问题,本文提出4S分类,将外资并购我国上市公司的模式分为四类:Superiorcategory... 外资介入中国上市公司的并购活动是资本市场发展的必然,其并购模式在一定程度上影响着并购重组上市公司的效果。结合我国宏观政策的倾向和外资并购中存在的问题,本文提出4S分类,将外资并购我国上市公司的模式分为四类:Superiorcategory优势类、Second-bestcategory可行类、Savedcategory保留类、Suspendcategory暂停类,并对各模式进行分析。 展开更多

For engineering applications of water dilution controlling system,the fluid dynamics of a mixed flow was studied with computational fluid dynamics(CFD) simulations and self-designed experimental set-up.In order to examine the predictability of CFD model for the headbox in industrial scale,two pulp suspensions before mixing were treated as homogeneous flows separately.Standard k-ε turbulence models with the mass diffusion in turbulent flows-species transport approach were applied in the simulations.A numerical simulation of this headbox model was analyzed with semi-implicit method for pressure linked equations scheme with pressure–velocity coupling.Results show that the model can predict hydrodynamic characteristics of headbox with injecting dilution water in a central diffusion tube,and the distribution of water content at the outlet of the slice lip is ideally normal at different speeds. 展开更多
