摘　　要：在电磁学和电动力学课堂教学实践过程中,关于哈密顿算子"▽"的运算非常频繁,并且"▽"所涉及的运算属于难点问题,导致许多学生产生畏难情绪,影响电磁学和电动力学教学效果.通过对电磁学和电动力学中关于"▽"的分析和归纳,发现"三度"(梯度、散度与旋度)及其相关的积分运算是疑难问题的症结所在,举例说明了其运算方法.In electromagnetism and practice to classroom teaching of electrodynamics course, the operation about Hamiltonian is very frequent, involves the operation belongs to the difficult problem, results in many students the fear of emotions, influences electromagnetism and electrodynamics teaching effect. This paper involves electromagnetism and electrodynamics and operation of classified analysis, and finds that the ＂three degrees＇, （scalar field the gradient vector field of the divergence and the vector field of rotation） and the integral operation is the crux of the knotty problems. Therefore, this paper illustrates the calculation method.
