摘　　要：利用1/︱r-r′︱的柱函数展开式及贝塞尔函数的性质,计算出均匀带电圆环片在空间产生的电势及场强,并对结果进行讨论;指出当所研究的问题具有轴对称性时,利用柱函数展开式能更方便地分析其形成的空间静电场,其求法对柱体、螺线管等形成的电磁场同样适用.Made use of the cylindrical function expansion and properties of Bessel function of 1/︱r-r′︱,we calculated the electric potential and electric field intensity generated by the uniformly charged ring slice in space in cylindrical coordinates,and discussed the results in this paper.When the research questions with axial symmetry,use the cylindrical function expansion,can be more convenient to analyze the formed electrostatic field in the space,where the method gilt for also the electromagnetic field formed by cylinder,solenoid,etc.
