The quick succession of strokes is what causes the lightning channel to flicker.
接二连三的快速闪击，则是使闪电通道闪烁的主因。
That is why the subsequent lightning that follows the completed channel often strikes a tall structure.
这就是接下来那些通过这条完整通道的闪电往往会击中高层建筑的原因。
Then a strong current of electrons follows that path from the cloud to the ground, and it is that current that illuminates the channel as the lightning we see.
然后一股强大的电子电流沿着这条路径，从云层到达地面，正是这种电流像我们看到的闪电一样照亮了通道。
The channel is only a few centimeters in diameter, but that is wide enough for electrons to follow the channel to the ground in the visible form of a flash of lightning.
这个通道的直径只有几厘米，但它的宽度足以让电子以闪电这样看得到的形式随着通道到达地面。
Those who regularly watch television sports channel viewers, in large-scale international sports competitions will see the "circle lightning" emblem, which is the German Opel logo.
凡是经常看电视体育频道节目的观众，都会在大型国际球类比赛中看到“圆圈闪电”的徽记，那就是德国欧宝汽车的标识。
A question of the assumed channel height is represented and the reasonable reasons are given. The conclusion is useful for calculating the lightning return-stroke electromagnetic fields in the future.
指出了国外文献计算回击电磁场时在选取通道高度方面存在的问题，并作出了合理的解释。
