“偏微分方程”課程中的高階學(xué)習(xí)探索
摘 要:本文以本科“偏微分方程”教學(xué)中涉及的格林公式與高斯公式為出發(fā)點(diǎn),通過復(fù)數(shù)乘積的幾何解釋,將格林公式與高斯公式在積分形式上統(tǒng)一為無空間維數(shù)要求的散度定理。進(jìn)而引入一般的分部積分公式,使學(xué)生對抽象積分有一個(gè)初步的了解,達(dá)到在“偏微分方程”課程中進(jìn)行高階學(xué)習(xí)探索的目的。

Abstract:Based on the Green's Formula and Gauss's Formula involved in the teaching of undergraduate partial differential equations,this paper unifies the Green's Formula and Gauss's Formula in integral form into a divergence theorem without spatial dimension requirements through geometric interpretation of complex product.Then,the general integral by parts formula is introduced to enable students to have a preliminary understanding of abstract integral,so as to achieve the goal of highorder learning and exploration in the course of partial differential equations.
Keywords:partial differential equations;mathematical physics equations;highorder learning
