According to the technological characteristics of soaking furnace of CSP line, the 3D-unsteady mathematical model of the loss of iron scale in soaking process was established with the experimental reheating furnace as instance by utilizing the methods of equivalent thermal resistance and equivalent mass. The effect of thickening of iron oxidation on heat transfer between gas and slab was considered in the model of loss of iron scale.

根据紧凑式带钢生产均热工艺特点，利用等效热阻和等效质量法，以实验均热炉为研究对象，建立三维非稳态钢坯均热过程氧化烧损数学模型，考虑氧化层的增长对传热过程的影响对氧化烧损量进行计算。

They consist of wire and cable, sheet, strip, plate, rod, bars, tubing, forgings, castings and powder metallurgy shapes.

它们包括电线电缆，板，带钢，钢板，型材，棒材，管材，锻件，铸件和粉末冶金形状。

Therefore, a suitable method used to analyze the welding seam defects is necessary for continuous rolling process.

因此希望能够找到一种有效的评价带钢焊缝抗断裂能力的方法。

In this case, defects in the welding seam are easy to expand, which may result in strip fracture and disturb continuous rolling production.

在这些力的作用下，带钢焊缝内部的缺陷可能会扩展，从而造成断裂，严重影响线连续生产。

According to the clear water experiment, aeration performance of the new equipment is good with high total oxygen transfer coefficient and oxygen utilization ratio.

曝气设备的动力效率在叶轮转速为120rpm～150rpm时取得最大值，此时氧利用率和充氧能力也具有较高值。

The environmental stability of that world - including its crushing pressures and icy darkness - means that some of its most famous inhabitants have survived for eons as evolutionary throwbacks, their bodies undergoing little change.

稳定的海底环境─包括能把人压扁的压力和冰冷的黑暗─意谓海底某些最知名的栖居生物已以演化返祖的样态活了万世，形体几无变化。
