An effective and energy saving heating system needs many control devices, such as flow controllers and differential pressure controllers.
每一个有效节能的供热系统都配有相应的调节控制设备，如自力式流量控制阀、压差控制阀等。
The capacity of controllers' working memories, thus, varies depending on (at least) experience, task demands, and time pressure.
管制员的工作记忆是随着经验、任务需要和时间压力而改变的。
