In the acceleratingfield, every unit adjusts its current by electric field strength, the total current remaining constant.
在加速场区，各单元按场强调整电流值，但电流总量不变。

Viewed from inside the tube, this field looks like an accelerating electrical pulse, and it is this pulse that picks up and carries the electrons-or, if the polarity is reversed, the protons.
从腔内看，此电场就如同一个加速电流脉冲，该脉冲可选中并携带电子，或在极性逆转时选中并携带质子。

The aurora borealis, caused by solar wind particles accelerating along Earth’s magnetic field, would have been visible as far south as present-day New York City.
