The upper part and the lower part in the electrostatic case are respectively provided with a negative plate, and a positive plate is arranged between the two negative plates.

在静电箱中的上部和下部分别有一个负极板，在两个负极板之间有一个正极板；

youdao

When water is pumped out of a chamber below the plate creating negative pressure, the stretchable sensors are pulled down, producing a concave shape.

当水从板下的一个腔中被抽出来产生负压时，可伸缩的传感器被向下拉，形成一个凹形。

youdao

When the charge is applied, if the upper plate is negative, we would expect that the negative droplet would be repelled at a rate exceeding the gravitational fall.

当电荷起作用时，如果上边的板子是负电的，我们可以期待负电的液滴会,超过重力下降速度的速度被排斥。
