振荡频率由电容储存电荷的能力,以及线圈生成磁场的能力所共同决定。
The frequency of this oscillation is controlled by the capacitor's ability to store charge and the coil's ability to produce a magnetic field.
空间电荷形成的虚阴极的位置和电势周期性地振荡。
The position and potential of the virtual cathode caused by space charge effects oscillate periodically.
在漂移区中考虑直流空间电荷场的影响。我们发现电子运动在该区服从一振荡方程;
We find out that, in drift, region, the motion equation of electron is an oscillation one, which influences the prcbunching of electrons.
我们再来设想一个理想实验,用某种外部影响迫使一个带有电荷的小圆球很快而且有韵律地像钟摆一样振荡起来。
Let us again imagine an idealized experiment. A small sphere with an electric charge is forced, by some external influence, to oscillate rapidly and in a rhythmical way, like a pendulum.
