The effect of Reynolds number on rudder hydrodynamic performance is also analyzed. Up to the stall angle the computed lift and drag agree well with measurements and other author's calculations, whereas stall angle, lift and drag beyond the stall angle are slightly under-predicted. The solver is used to investigate laminar and turbulent separated flows around a 6: 1 prolate spheroid at high incidence angles and their effects on hydrodynamic forces. The second separation flows are successfully identified in both laminar and turbulent flow simulations.

There are some main conclusions of the article. 1.Enterprise inclines to decision-making according to its profit, so constituting and anglicizing green institutions from the view of enterprise will advantage their microcosmic base, then can improve their adaptive abilities and green effects. 2.Government has powers and some potential advantages, but it inheres of some defects, so it should not become the principle parter but the urger, waiter and superintendent of the green transition process. 3.According to social cost and the situation of the social environment, we should adopt a gradual transition stratagem on the whole in the process. 4.We can classify the enterprise green transition into three kinds by the dominant factor in the push-drag-model, push-dominant mode, drag-dominant mode and friction-tight state. Different green policies should giveto different transition mode in odor to getting a good green effect. 5.The costs of enterprise have three levels by the point of view of sustainable development, apparent cost in generation, dormant cost in generation and intergenerational cost. The priority of green system should adjust to the level to which the benefits of the enterprise amount.

本文得出的主要结论有：1、企业具有相机决策的倾向，从企业的角度分析和制定绿色制度可以使政策具有较强的微观基础，进而可以提高它的适应性和绿色效果。2、政府具有暴力潜能，也具有固有的不足，在绿色制度变迁的过程中应该且只能是倡导者、服务者、监督与维护者，而不是主体参与者。3、综合考虑社会成本与社会环境，渐进式的总体推进模式是我国目前较为现实的选择。4、本文建立了企业绿色变迁推拉模型，并根据促使企业绿色转变的主导因素的不同，将企业绿色变迁的模式分为拉力主导型、推力主导型与摩擦状态三种类型，不同的类型应采取不同的绿色政策才能收到良好的绿色效果。5、从可持续发展的角度可以将企业的生产成本分为代内隐性成本、代内显性成本和代际成本三个层次，对于收益处于不同层次的企业，绿色制度的侧重点应有所不同。6、根据企业与政府在绿色制度变迁过程中所起的作用的不同可以将绿色制度变迁分为强制供给型、政府导向型、需求诱导型三种模式。
