Method dispatches the specified exception to the server through the reply sink specified in the constructor of the current sink stack 通过当前接收器堆栈的构造函数中指定的答复接收器,
If the current sink stack was created without a reply sink , the message is not transmitted , and no new exception is thrown 如果当前接收器堆栈在创建时未带答复接收器,则不传输消息并且不引发任何新异常。

Since a pentode presents a fairly constant current sink , trying to power it from a constant current source will be fairly unsuccessful , sort of like the unstoppable object hitting the immovable object 因为五级管本身就表现得类似恒流陷阱(意思是消耗恒定的电流) ,试图用恒流源驱动五级管只会是个失败,就好像试图用一个停不下来的物体去打击一个不可移动的物体。
Current mirror circuits may be found in two basic varieties : the current sinking configuration , where the regulating transistor connects the load to ground ; and the current sourcing configuration , where the regulating transistor connects the load to the positive terminal of the dc power supply 镜像电流源可能以两种基本的类型出现:调整管连接负载到地的吸电流结构;以及调整管连接负载到直流电源正极的灌电流结构。
