摘要
从一个具体的物理问题入手,探讨了如何将第一类曲面积分转化为两个第一类曲线积分的累次形式,从而给出了这两类积分之间的关系,并通过举例说明该公式可以用来直观简便地计算第一类曲面积分.
Through a physical problem,this paper describes how to convert the first surface integral to the first line integrals,thus establishes a new relationship between these two kinds of integrals.With examples,this paper shows that the given formula can be used to compute the first surface integral in a simple and intuitive way.
