化学家们修补了热催化器与金属催化器以精炼材料。
The chemists have tinkered with heat and metal catalysts to refine their materials.
根据能量平衡原理，建立了基于预热燃烧风富氧下铜精炼阳极炉高温烟气热损失数学模型，并根据富氧燃烧风对铜精炼阳极炉氧化期高温烟气热损失数学模型进行计算。
A mathematical model of heat loss of high temperature smoke vented from rotary anode furnace in copper refining based on warm-up burning air was established based on principle of energy balance.
且铜精炼氧化过程炉膛具有很大的热惯性，这直接导致炉膛烟气温度动态响应速度很慢、动态过程时间很长的现象出现。
Furthermore, the value of heat inertia in the hearth of copper refining rotary anode furnace in the reduction phase is so big that smoke temperature change can not quickly respond to the disturbance.
