  1. In order to find the detecting signal characteristics of all kinds of flaws for ect and ac - mfl, itestablished the signal analysis method based on rectangular flaw, which was validated throughthe experimental research on ect and the emulational research on ac - mfl for different shapeand dimension flaws. the method was explained that a flaw with an arbitrary shape can berepresented as a set of flaws with the simplest rectangular shape. as the synthetic application of these researches, the problem of defect detection of bolt wasresearched

    為實現螺紋區域中的缺陷檢測，提出了提取局部極大值的缺陷識別方法;並根據位置的不同將缺陷分為螺桿結合部缺陷、螺紋區域缺陷以及螺紋尾部缺陷三類，對每類缺陷的信號特點進行了分析，給出了缺陷檢測的判據，並通過實驗驗證了識別方法的可靠性;最後對螺栓頭桿結合部的缺陷檢測進行了實驗研究，並根據信號特點建立了相應的缺陷檢測方法。
