Maintain deflector if the size of the same voltage, the voltage change is accelerating, we can see a very accelerated voltage reduce, electron beam deflection angle instead of increasing, it is because of low accelerating voltage, the electron velocity smaller horizontal direction, electronic deflection plates in the field of the role of the extended time, the angle of deflection increases .

如果保持偏转板的电压大小不变，改变加速极的电压，可以看到加速极的电压减小，则电子束偏转的角度反而增大，这是因为加速极电压低，则电子的水平方向速度变小，电子在偏转板中受电场力作用的时间加长，所以偏转的角度增大。
