第1型曲線積分與曲面積分的'1些問題
摘 要
本文歸納研究了第1型曲線積分與曲面積分的物理背景，定義，性質及計算方法，並在此基礎上給出了它們在特殊座標變換下的計算公式及證明。並且利用這個公式，推匯出了當第1型曲線積分或曲面積分的被積函數爲奇函數或偶函數，積分曲線或曲面是對稱的時的幾個重要的推論及證明。
關鍵字：第1型曲線積分與曲面積分；座標變換；奇偶性；對稱性。
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 ,and 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
