微元分析法在工科物理教学中的应用

Understanding and Application of Differential Element Analysis in Engineering Physics

阐述微元分析法的原理,大学物理中的应用步骤,包括建立物理变量间对应关系、变量替换、物理量微元的选取,以及在其他坐标空间中的扩展应用,给出不同解法的成因和区别,从而更好地理解与掌握微元法的思维方式。

This paper expounds the principle of differential element analysis and the application steps in college physics,including the establishment of the corresponding relationship between physical variables,variable substitution,the selection of physical quantity differential elements,as well as the extended application in other coordinate spaces,and gives the causes and differences of different solutions,so as to better understand and master the thinking mode of differential element method.
