    The potential difference across the electrodes is called the retarding potential difference or voltage. As the magnitude of the retarding voltage is increased, an increasing number of electrons fail to reach the anode.

    在光電倍增管的正負極施加一電壓以控制光電反應所產生的電子到達正極的電子數, 此施加的電位差(或稱電壓)就是retarding voltage. 當延遲電壓(retarding voltage)增加時, 就有更多電子無法到達正極.

    Retarding voltage 請參考以下網址解釋: http://www.equalrightsforall.net/online_tutorial/m...
