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

加到每个光倍增管的压决于PMT的设计，由每个管子的型号来。

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

安计在最后一个倍增管处读取流，此流等于阳流减去流过前一个倍增管的流。
