介绍了一种基于超声导波的高温超导体超导量子干涉仪（SQUID）无损检测技术。利用磁致伸缩效应产生和接收超声导波，构建了基于超声导波的高温超导SQUID无损检测系统。利用该系统测量了T（0，1）模超声导波在铝管上传播时产生的磁信号，研究了HTS-SQUID梯度仪方向、提离距离、磁致伸缩发射机输入电流的强度和频率等测量参数对磁信号的影响。与梯度仪定向平行于管轴，大于10倍的信号被测量相比，定向垂直于管轴。梯度计测量的磁信号与列出距离的幂成正比，并与高达1A pp的输入电流强度成正比。给出并讨论了输入电流频率与被测信号的关系。
This article describes research on the novel high-temperature superconductor (HTS) superconducting quantum interference device (SQUID) non-destructive evaluation (NDE) technique for metallic pipes based on ultrasonic guided waves. We constructed HTS-SQUID NDE system for pipes based on ultrasonic guided waves, which were generated and received by means of the magnetostrictive effects. Using the system, we measured magnetic signals due to T (0, 1) mode ultrasonic guided waves that transmitted on aluminium pipe, and investigated influences of measurement parameters to the magnetic signals, such as direction of a HTS-SQUID gradiometer, lift-off distance, and intensity and frequency of input current fed to a magnetostrictive transmitter. With the gradiometer oriented parallel to the pipe axis, more than 10 times larger signals were measured compared with that oriented perpendicular to the pipe axis. Magnetic signals measured by the gradiometer were inverse proportional to the power of the list-off distance, and proportional to the intensity of the input current up to 1 A pp. Relation between the frequency of the input current and the measured signal was shown and discussed.
