How to Handle the Charge Volume of a Ball Mill or Rod Mill

网页In physics, the charge of a volume is commonly described by a quantity called the charge density or the charge distribution. When the electric field that arises from the charge distribution exhibits a volumetric symmetry, a handy relationship known as Gauss’s Law may be used to calculate the charge distribution of the volume. The charge volume of a
