变上限积分求导数法在物理学中应用

Application of Derivative of Variable Upper Limit Integral in Physics

本文利用变上限积分求导数的方法解决了感应电势的求解问题，并举例说明。

By using the derivative of variable upper limit integral, the solution of induction electromotive force (IEF) is given. Some examples illustrate that the method is more simple than the previous calculation about the IEF.
