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

加到每个光倍上的压决定于PMT的设计，并由每个子的型来确定。

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

皮安计在最后一个倍处读取流，此流等于阳流减去流过前一个倍的流。
