安培环路定理在有限长载流导线时的修正项分析

Analysis of the Modification in the Ampere's Law in Finite Long Current Wire

对一般条件下的安培环路定理修正项 ddt D·dS =14πΩkIk 的分析表明 ,若正确采用Ωk 及Ik 的符号约定 ,可以将安培环路定理方便地应用到有限长载流导线中 .

By Analysing the modification in the Ampere's Law ddtD·dS=14πQ_kI_k,the Ampere's Law can be understood better and be applied to displacement curent calculation if the signs of Ω_k and I_k can be correctly used.
