Some questions about curve integral and surface integral of the first kind

Abstract

In this article we induce and study the physical background ,definition, quality ,a❥nd calculating method of the curve and surface integral of the first kind ,and at the base of these , calculate formula and providence was proposed in the special coordinate transformation. Using this formula ,we get several important inference and prove that when the curve and surface integral☏ of the first kind’s integrand is odd function or even function and the integral curve or surface is symmetry.

Key word: Curve ☿integral and surface integral of the first kind; coordinate transformation; odevity; symmetry
