CO partial pressure(A decrease in the CO partial pressure at low carbon contents will be greater in OBM than in BOF practice. 在含碳量较低的情况下， OBM 炼钢法 CO 分压的下降幅度大于 BOF 炼钢法。)
partial pressure of CO in gas bubble(With the bottom injection of argon in the BOF combined-blowing practice, and the presence of hydrogen in the gas bubbles in OBM, the partial pressure of CO in the gas bubbles will be lowered in both processes when the rate of CO generation decreases. 带有底吹氩的 BOF 复吹实践和 OBM 炼钢时气泡中存在氢时，如果 CO 的产生速度下降，则这两种炼钢法气泡中的 CO 分压将会降低。)
