临界点含碳量(【技】在钢水冶炼过程中，当钢水含碳量较高时，脱碳速率的主导限制因素是氧的传质速率；随着脱碳反应的进行，钢水中含碳量降低到一定的浓度值后，脱碳速率的主导限制因素由氧的传质速率转变为碳的传质速率，脱碳速率出现明显下降，此时的碳含量称之为临界含碳量。: As seen in part (b) of Figure 9, the carbon content at the critical point is about 0. 688 weight percent and the mean value of the decarburization rate is about 0. 102 weight percent/minute, with standard deviations of 0. 11 and 0.01, respectively. 如图 9(b) 所示，临界点含碳量约为 0.688 质量分数，脱碳速度平均值约为 0.102 质量分数/ min, 标准偏差分别为 0.11和 0.01。)
终点控制系统(For example the basic oxygen furnace (BOF), several end-point control systems have been developed to control steel temperature and composition at the end of oxygen blowing. 以氧气顶吹转炉 (BOF) 为例，现已开发出若干终点控制系统，用于在吹氧结束时对钢水温度和成分进行控制。)
氧气顶吹转炉终点控制系统(① We have developed the endpoint control system of basic oxygen furnace (BOF) and applied the system to automatic oxygen blowing control. 我们已经开发出氧气顶吹转炉终点控制系统，并将该系统运用到吹氧自动控制。② We can thus get the target temperature at end of oxygen blowing by using the endpoint control system of basic oxygen furnace (BOF). 通过使用氧气顶吹转炉终点控制系统，我们就可以得到停吹氧目标温度。)
碰撞点(【技】碰点：高炉炼铁术语，指在高炉布料的过程中，大钟打开后，炉料从大料斗内沿高炉大钟斜面流下，炉料离开大料钟斜面后，在重力的作用下降落、碰撞到炉喉上的部位。: Burden profile depends on the vertical distance between the impact point and the burden surface, the type of burden material, and the existing burden surface profile. But, in general, an M-shaped profile will be formed. 料面形状取决于碰撞点和料面之间的垂直距离、炉料类型以及原来的料面形状。但是一般而言将形成 M 形料面。)
