【Abstract】 The proof of the boundary condition in the static electric field is almost the same in most of physics textbook for college students.It looks as if the conclusion is related to a particular process and confuses students easily. In this article, the same conclusion has been derived from an alternative process. It follows that such a boundary condition independent of the way to prove represents the objective law of the static electric field .更多还原
