在化工厂中,化学反应器的控制比较困难。尤其是某些化合物被混合时,如果输入物料的比例不对,就有可能随时引起燃烧甚至爆炸。操作人员在控制这类反应器时,需要非常小心,特别是在开车和停车时,或一个操作程序开始和终了时,更不容有误。对这种场合,采用计算机控制,有十分明显的优越性。 In chemical plants, chemical reactors are more difficult to control. In particular, some compounds are mixed, if the input material ratio is wrong, it is likely to cause combustion or even explode at any time. Operators need to be very careful when it comes to controlling such reactors, especially when driving and parking, or at the beginning and end of an operating procedure. For such occasions, the use of computer control, there is a clear advantage.
