摘要
在解决定积分应用问题中,微元法是一种有效的方法。从几何、物理、经济等几个方面论述了微元法及其应用,并把微元法推广到重积分和广义积分中去。由此可见,微元法在解决某些实际问题中发挥着重要作用。
Infinitesimal method is an efficacious method in solving application problems of the definite integral. The paper discusses the infinitesimal method and its application on the aspects of geometry, physics and economy. Then the method is generalized in the multiple integral and the improper integral. And we can come to a conclusion that the infinitesimal method plays an important role in solving some practical problems.
