外微分在微积分中的应用

The Application of Outside Differential in Calculus

引进外积和外微分的概念后,用来解释微积分中的二重积分变量变换式、场论中的格林公式、斯托克斯公式和高斯公式。

After the concept of outer product and outside differential has been introduced,it is used to explain double integral variable transforms in the calculus,green＇s formula in the field theory,a stoke formula and the Gauss formula.
