| 摘 要： | 应用电磁场理论和有限元分析方法，系统地分析了远场涡流中能量流的变化规律，并重点讨论了似稳态激励和瞬态激励两种情况下的扩散能量流的似波特性。研究结果表明，能流分界线可以形象地表示能量在一个周期内的变化规律；能量变化与源的变化之间有一个时间滞后，呈现了似波特性。

| Abstract: | The remote field eddy current (RFEC) technique is a new powerful tool for pipe inspection. ln this paper the diffusive energy flow of RFEC has been systematically analyzed with finite element method upon electromagnetic theory. Results show that it has wave-like phenomena for diffusive energy flow of RFEC in both quasistatic and translent excltion. |
