这里的lined out怎么翻译? normally operation can have the level or weight controller set at a minimum safe level or weight (20% lower than designated level or weight ) to prevent the system timer from dumping the bed .the timer should always be the primary means of control .the level or weight controller should only be used as the primary means of control if the reactor is in a steedy ,lined out condition .this way of operation is advisable (明智的)to keep the vent recovery system from being upset (颠覆、扰乱、混乱). 谢谢大家啊,这是整个的一段,按照前面的应该先选计时器控制啊?查看更多
