提出利用微波进行玻璃钢抽油杆无损探伤的方法 ,简述了反射法检测系统的基本组成 ,并以提取探伤信号的波峰中点对应采样点数、波峰面积、波峰峰值及波峰面积与峰值比作为特征 ,对气孔类缺陷的位置、体积、气孔沿抽油杆径向的深度和轴向分布的长度进行了定性分析 The method of non-destructive testing of glass fiber reinforced plastic sucker rod by microwave was proposed. The basic composition of the reflection detection system was briefly described. The sampling points, peak area, peak and peak area and peak ratio of the midpoint of the detected signal were extracted , Qualitatively analyzed the position and volume of stomatal defects, the depth of stomatal along the radial direction and the length of axial distribution
