本文论述了电像法的局限性及其应用中所遇到的困难。通过电像法在两平行平面边界的应用,着重指出:电像法的简单化与形式化的直接应用,往往由于级数的逐项积分不可能性而导致错误的结果。并给出了克服级数不可积性的四种有效方法。
This article discusses the limitations of the image method and the difficulties encountered in its application. The application of the electrographic method to the boundaries of two parallel planes emphasizes that the direct application of simplification and formalization of the electrographic method often leads to erroneous results due to the impossibility of the item-by-term integral of the series. In addition, four effective methods to overcome the non-integrability of series are given.
