But when a Mo foil is placed on the inwall of the reaction crucible, the final content of carbon in Fe-C droplets can reach a very low level. 当反应坩埚内壁衬有金属钼片时，金属颗粒的终点碳含量可以降到极低的水平。
In the light of the inwall depression in the process of tubular intermediate upseting, a parallel velocity field model with depression is established. 针对管坯中部锻锻变形过程中产生的内壁凹陷现象，建立了含凹陷的平行速度场模型。
