This paper proposed a new type electromagnetic brake technique that called vertical electromagnetic brake(V-EMBr),which applied to the slab continuous casting process.A three-dimensional mathematical model is developed to describe molten steel flow and the interfacial behavior of molten steel/liquid slag in the mold with vertical electromagnetic brake,considering the coupled effects of electromagnetic field and flow field.The effect of magnetic flux density,casting speed and the submergence depth of the SEN on flow field in mold with V-EMBr are investigated by numerical simulation method.Meanwhile,the effect of current density on the interfacial behavior of molten steel/liquid slag is also investigated with Volume of fluid(VOF)model.The results show that the application of V-EMBr can play an effect control to the molten steel in the mold,and significantly reduce the flow intensity in upper recirculation zone,decrease the impact strength of jet flow on the narrow face and the flow velocity of molten steel in the free surface of mold.At the same time,the height of molten steel/liquid slag interface can be obviously depressed by V-EMBr with increasing of current density,which is beneficial to reduce the possibility of mold flux entrapment.

随着生产水平的日益提高，水稻不仅被作为重要的粮食作物，还被作为经济作物和饲料作物，具有巨大的开发利用价值，因此，它对我们的生活和生产越来越重要。尽管近几年水稻的产量和品质都有所提高，但是仍然受到许多不利条件的影响。当前，进一步培育新的水稻品种才是我国农业科技发展的重要工作，利用分子生物学技术和植物基因工程方法，成为解决此项工作的新的有效手段。在细胞中，有限的蛋白磷酸酶和很多蛋白激酶共同维持着蛋白磷

涂层防腐是目前应用最广泛、最经济实用的防腐方法。环氧树脂分子中环氧基、羟基等极性基团存在,使其对金属基体具有良好的附着力;主链上只有极性较小、稳定的C-C键和醚键使环氧树脂具有良好的耐蚀性能。为适应环保的要求,水性环氧防腐涂料得到发展,但同样存在交联固化后密度高,抗冲击韧性差、性脆、易开裂等缺点。聚苯胺防腐涂料具有独特的耐蚀机理,防腐性能优异,但聚苯胺单独成膜附着力低,聚苯胺具有难溶性,这对其应用
