摘要
本文阐述了求解场能量及其等效参数的双界能量原理，推导了交变电磁场的双能量表达式。并应用这些公式求解场中薄导体板的等效电阻和电感，与解析法的计算结果相比较，证明它们具有较高的计算精度。
ln this paper,the principle of dual energy method used for calculating the energy and parameter of electromagnetic field is expounded.The dual energy expressions of alternating current electromagnetic field are deduced.These formulas are used in the calculation of resistance and inductance of a thin steel plate. Comparing with the results calculated by the analysed method,it showed that high accuracy had been obtained by using these formulas.
