通过对双晶探头距离—波幅特性曲线当量误差的检验实验 ,研究用该曲线评定 6mm~ 2 0 mm中厚钛板中的缺陷反射信号是否超标的可靠性 ,并给出实验数据。
Based on the test of the equivalent error of distance-amplitude characteristic curve of dual-crystal probe, the reliability of using this curve to evaluate whether the defect reflection signal in 6mm ~ 20mm medium thick titanium plate exceeds the standard value is studied and the experimental data are given.
