摘要
"微元、定积分"的应用几乎贯穿了《普通物理学》的整个教学过程,其在物理学中有着极为广泛而重要的应用.利用"数学微元"的思想将变力做功、液体压力、转动惯量和感应电动势等存在的物理问题做了分析、研究,建成微元定积分模型,通过举例分析,总结解决物理学问题的"微元积分"法.
＂Infinitesimal＂ and ＂the definite integral＂ are almost concerned of the whole process of ordinary physics teaching, which has a very extensive and important application in physics. In the article, the physical problems of ＂the variable force pow- er＂,＂ liquid pressure＂, ＂moment of inertia＂ and ＂induced electromotive force＂ are researched and built into infinitesimal model of definite integral. Then the ＂infinitesimal integral＂ method is argued to solve the physical problems by examples and analysis.
