average taphole service life(In spite of the rapid increase in the average taphole service life, its performance is not stable. 尽管出钢口平均寿命迅速提高，但其性能却不稳定。)
average production per caster(In spite of the progress made, it is clear that the average production per caster in the area is still far below the level of production which can be technically achieved today. 尽管有所进步，但显而易见的是该地区平均单(台连铸)机产量依然远远低于目前在技术上可以达到的产量水平。)
average heat flux(The agreement between the average heat fluxes in the mold calculated by the mathematical model and by the cooling water temperature rise is particular good for the trials with the stainless steel. 对使用不锈钢所进行的试验而言，根据数学模型计算出的结晶器内平均热通量与根据冷却水温度升高计算出的结晶器内平均热通量十分吻合。)
average decarburization time(① Figure 13 shows the change of average decarburization time for each steel grade after revamping of RH facility. 图 13显示了 RH 装置改造后每一钢种平均脱碳时间的变化。②The average decarburization time before upgrade of the RH unit is calculated by the operation data of the year1996. 这台 RH 设备改造前的平均脱碳时间是根据1996 年的操作数据计算的。)
average hot metal temperature(The results of the computer simulation indicate that the hot metal ratio can be decreased from 78. 8% to 70. 0%, if the average hot metal temperature is increased by 200°C 计算机模拟结果表明，如果铁水平均温度提高 200°C ,铁水比可以由 78.8% 下降到 70. 0%。)
average annual production per blast furnace(Average annual production per blast furnace is approx. 1. 26 million tonnes of hot metal； the largest furnace produces over 4 million t / a. 高炉平均年产量约为 126 万 t 铁水，最大高炉年产铁水超过400万 t。)
