This occurs because the plate current in a class AB amplifier is not continuous for the entire AC cycle.

这是因为该板块目前在AB类放大器是不连续的整个交流周期。

Plate current only flows when a signal is present, and only flows for exactly half, or 180 degrees, of the input cycle.

板目前流动时，只存在一个信号，只有流动的一半，或180度，输入周期。

Cutoff refers to plate current cutting off on one side of a push-pull pair for a portion of the cycle, while the other side continues to function.

截止目前指板切断一方的推挽对一个周期的一部分，而其他方面继续发挥作用。

Small changes to the voltage of the grid control large changes in the electron current flowing to the collector plate.

This year, the latter group is stepping up to the plate and beginning to place bets buoyed by the strength of current business results, strong balance sheets and their pent-up need to find growth.

FORBES: Davos: This Was One Of The "Good" Ones

Weighing 140kg, with hands like buckets and a face as flat as a plate, he waded into the marquee as if against a strong current of water and assumed a position in the corner.
