【摘要】 重积分从定义到基本性质与定积分理论基本上是平行的,但由于空间结构的变化,又显示出重积分与定积分的本质差异.本文通过若干实例说明重积分与累次积分是两个独立的概念,它们的存在性没有必然的蕴含关系,并指出只有在一定条件下它们之间才存在相等关系.更多还原

【Abstract】 The theory of multiple integral is basically parallel to that of definition and main nature. But because of the charges of the space frame, they also present the essential distinction. This paper using several instances, analyses that the multiple integral and repeated integral are two independent concepts and there is no certain implication between them. It also points out that only when they meet some certain requirements can they be equal to each other.更多还原
