Transferable emission permit — a pollution control policy requiring each emitter of a pollutant to possess permits for the amount of pollution it releases.
可转让许可系统——污染物控制政策要求每个污染排放源拥有污染排放许可。
For example, a transistor is a controllable switch, but it is directional between the collector and emitter, and it has interactive control between the base and emitter.
例如，晶体管是可控的开关，但它在集电极和发射极之间是定向的，并且在基极和发射极之间是配合控制的。
Moreover, the collector of switching transistor is also connected to an output end of PG signal directly. The emitter is also connected to an input end of a control signal directly.
此外，该开关晶体管的集电极还直接连至一pg信号输出端，发射极还直接连接至一控制信号输入端。
The beam emitter is located at a ground-based unit and operated by a person, who could control it from the same location or remotely from an entirely different place altogether.
光束发生器被安装在一个接地装置上，可以由一个人在原地操作，也可以进行远距离操作。
