1、is found that the convection heat transfer plays an important part in the bulk above the return flow section and the heat conduction only rises in the bottom region.───表明，回流口截面以上区域传热以对流方式为主，底部区域则主要是逐层导热。
2、In high Reynolds number range of 10,000 ~ 90,000, the flow friction factor, local and average convection heat transfer coefficients were determined.───在10,000 ~ 90,000的高雷诺数范围内，测量了流动摩擦系数、局部和平均对流换热系数。
3、While the effect of the convection on heat transfer can be neglected at low power densities, melt flow assumes its importance as the power density increases.───随着功率密度的加大，对流的作用增强，其影响不可忽视。
