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。

When that glass is then "read" by a laser, the voxels produce tiny whirlpools of light, the properties of which have already been determined by the polarity of the laser pulse that created each voxel.

当这个玻璃通过激光进行"读取"时，体素会产生微小的光漩涡，这些光漩涡的属性是由形成每一个“体素”的激光脉冲所事先决定的。

The positive polarity pulse will make better result for the samples than use negative polarity pulse.

对平行极化、方向指向阳极的样品，只要极化电场强度不是很大，宜选用正极性极化脉冲；

Each pulse switches the polarity, writing a one or a zero.
