停留时间分布(The Residence Time Distribution (RTD) curve shows that at the outlet, a tracer pulse arrives a certain time after the start of the experiment; the signal rises quickly to a peak and then diminishes exponentially to zero. 停留时间分布曲线表明，在试验开始后的某一时刻示踪剂脉冲到达出口处时，脉冲信号首先快速达到峰值，然后按指数曲线衰减至零。)
【连】 钢水停留时间(【技】钢包注流进人中间包到流人结晶器的路程中，钢水在中间包内所经历的时间。单位通常用 min 表示。钢水在中间包内停留的时间越长，钢水中夹杂物上浮的时间就越充分，钢水就越干净。: ① The trial revealed that baffle boards increased the steel residence time and enhanced nonmetallic inclusion floatation. 试验显示:缓冲板提高了钢水停留时间、促进了非金属夹杂物上浮。 ②Baffles, weirs, and dams have long been in use to increase steel residence time and promote inclusion flotation to the tundish slag. 为了延长钢水停留时间、促进夹杂物上浮到中间包渣中，缓冲板、双挡墙已使用了好长时间。)
