The voltages that should be applied to each dynode are a function of PMT design and are specified for each tube type.

加到每光电倍增管电上的电压决定于PMT的设计，并由每管子的型来确定。

The picoammeter reads the current at the last dynode, which is equal to the anode current minus the current flowing to the previous dynode.

皮安计在最后倍增管电处读取电流，此电流等于阳电流减去流过倍增管电的电流。
