| 摘 要： | 明确地给出了广义del算子的定义和它与狭义算子之间的关系，指出当狭义del算子与任意张量的运算结果仍为一张量时，狭义del算子完全可用广义del算子替换；否则，狭义del算子不能用广义del算子替换．该文对于统一目前有关场论著作中的符号以及电磁场理论的教学具有重要的作用．

| Abstract: | Definitely defines generalized del and sets out the relation between special del and generalized del. When the operating result of special del and any tensor is still a tensor, it can be replaced by generalized del; if not, it cannot be replaced by generalized del. The paper is important to unify symbols concerning field theory and to the teaching and learning of electromagnetic field theory presently. |
