This paper, firstly, introduces some basic nondestructive tests, shows the background of the subject about the test for the defect of sucker rod, by comparing with the other nondestructive tests, proves the advantage of eddy - current test, then beginning with maxwell equation in electromagnetic field theory and combining with the idea model of defect, this paper proves that the feasibility of eddy - current test technology in multi - parameter and multi - frequency which applied in the test for for the defect of sucker rod
本文首先介紹了無損檢測技術的幾種典型方法，並給出了抽油桿裂紋檢測這個課題的背景，通過同其它幾種無損檢測技術的比較，給出了電渦流技術的優越性。然後從電磁場理論中的麥克斯韋方程出發，結合裂紋的理想模型，從理論上證明了電渦流多頻率多參數檢測技術在抽油桿裂紋檢測中的可行性。
