摘要
微元法是大学物理学中一种基本而又重要的分析方法。文章通过匀质半球体质心位置的计算,说明了微元的选取及其在坐标系中的表示是灵活多样的,应根据具体问题选取合适的微元及坐标系,从而简化运算过程。
Infinitesimal element analysis is a basic and important method in university physics. In this paper, through calculating the centroid position of homogeneous hemisphere, it indicate that the element selection and repre-sentation in the coordinate system is various and should be selected according to the specific problems, so as to simplify the calculating process.
