| 摘 要： | 在具有轴对称特性电磁场的数值分析中,用矩形截面环单元分析具有比其他单元更多的优点。本文推导出了该单元的拉普拉斯方程、泊松方程和波动方程的单元特征式。并运用该单元成功地分析了圆柱形电容器的场结构和加载同轴腔端部的电容值和品质因数。

| Abstract: | In the numerical analysis of axially symmetry electromagnetic field, the finite element method using ring unit with rectangular cross -section has more advantages than other methods. The ring unit characteristic equations in relation to Laplace s, Poissou s and Helmholtz s equa.tions are derived. Using this method, the field structure of cylindrical capacitor and the capacitance and quality factor of the end of laded eoaxial cavity are successfully analyzed. |
