摘　　要：尽管经典理论比起量子理论来 ,有很大的不足 ,但是它仍然是一个自洽的理论 ,并且它是量子理论的基础 ,对于量子理论有很大的指导意义 .本文分析研究了经典场论的基本理论问题 。Although the classical theory is very much not full than the quantum theory, it nevertheless a self-consistent theory. Moreover, it is the foundation of the quantum theory, and it has the great guiding sense to the quantum theory. It will, therefore, be usefull to be familiar with the calssical field theory. This paper analyses and studies the fundamental theoretical ploblems of the calssical field theory, mainly, the problem of treating electromagnetic energy-momentum tensor, using the variational principle for classical fields.
