The author points out: if lots of the conflicts of philosophical foundation the 20th century's quantum mechanics faced with, well-known to everybody, should be logically attributed to the confusions of the some fundamental concepts in the classical electromagnetic field theory, the series of logic inconsistencies implied in the classical electromagnetic theory and the forms of difficulties the modern computational electromagnetism encounters while solving time-varying electromagnetic field should be also logically attributed to an anomalous fact that series of fundamental mathematical propositions relating with bispinor differential operator, which naturally appears in the formal expression about dynamic electromagnetic field, have not be solved really while the related complete mathematic physical models or well posed boundary value problems have not been built.

著者指出：如果说20世纪的量子力学之所以面对哲学基础众所周知的矛盾，在逻辑上最终不能不归咎于经典电磁场理论体系的一些基本概念并没有真正得到澄清的话，那么，经典电磁场理论体系隐含的众多逻辑不自洽问题与目前计算动态电磁场所面对的困境，则必须逻辑地归咎于与双旋度微分算子相关的一系列基本数学命题并没有解决，而相关的恰当数学物理模型至今没有真正建立起来的缘故。
