The coulombmeter function of the electrometer measures charge by integrating the input current.

在其输入级的反馈回路中使用了一个积分电容器。

Superior part-load efficiency is another virtue in the proposed system, for the input current of the resonant tank is decreased with the decrescence of load.

同时谐振槽输入电流随负载的减小而减小，提高系统的部分负载能效值。
