就图 1所示空腔内的均匀电场 ,以电荷密度 ρ分布的电荷分布范围有一定的任意性 。
In terms of the even electric field in the cavity illustrated by picture 1, the range of distribution of electric charges which are distributed according to electric charge density ρ has a certain arbitrariness, but the distribution on the surface of the ball, according to the cosine and the equivalent cosine law of some basic electric charges which excite the even electric field,is unchanged.
