电磁场边界条件的一种新推导方法

对由不同煤质所组成的电磁场场域，当分界面上场的散度源和旋度源不为零时，场量将在分界面两侧发生突变，通常使用的单一煤质区域中的斯托克斯公式不再适用这种情况，推广了单一煤质中的斯托克斯公式，得到了适用于多媒质区域的多曲面斯托克斯公式，对于由不同煤质所组成的电磁场场域，利用所推广的多曲面斯托克斯公式，给出了电磁场边界条件的一种新的推导方法，所推导的公式对于由多种媒质组成的矢量场有广泛应用。

A New Development for Boundary Conditions of Electromagnetic Field

For the electromagnetic field formed by different mediums, when the divergence source and the curl source on the interface are not zero, the field will change across the interface. The general Stokes formula for the single medium is not applicable to this case. The paper extends the formula and obtains Stokes formula suitable to multi-medium. For the vector field made by different mediums, we give a new method to develop the boundary conditions using the Stokes formula and Gauss formula for multi-medium. The method presented in the paper is more general. The formulae presented have more applications in vector field formed by multi-media.
