The imbalance between oxygen requirement from Linz-Donawitz processsteel-making system and oxygen supply of supporting air separation unit is analyzed.
分析了氧气顶吹转炉炼钢的氧气需求量与所配套空分设备氧气供应量之间的不均衡关系；

Yet these oxides must be stripped of oxygen molecules in the steel-makingprocess, which requires vast amounts of energy.
然而，在制造钢铁的过程中，我们必须将氧化铁中的氧分子分离出来，这一过程需要大量的能量。

In the process of steel-making, killing oxygen by adding aluminum process is a controlled object whose parameters are distributed and non-linear, and its observed data are discrete.
