So, in the most general form, Coulomb's law is the product of the charge, q1 And, in order to rationalize electrostatic units with mechanical units, we have to put a factor in here.
在一般情况下，库仑定律是电荷的产物，和q2之间的距离就是半径r，q1q2，divided，by，their，separation，，which，is，r。,为了使最后算出的合理的静电单位和力学单位,我们需要在这儿引入一个常数。
At present, our large generating units mainly adopt electrostatic precipitators, while the old units adopted water precipitators.
目前我国大型机组基本采用静电式除尘器，而老机组多采用水膜式除尘器。
