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

加到每个光倍增管上压决定于PMT设计，并由每个管型来确定。

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增管处读取流，此流等于阳流减去流过前一个倍增管流。
