算法在改善电磁超声系统数据波形质量、提高系统的检测准确性方面具有一定参考作用。
An electromagnetic acoustic transducer (EMAT) can produce and receive ultrasonic waves though electromagnetic coupling.
电磁超声换能器(EMAT)是一种通过电磁耦合方法产生和接收超声波的换能器。
The EMAT is characteristic of non-contact and being needing no coupling medium, so it is specially concerned by researchers on nondestructive testing and evaluation.
由于EMAT具有非接触性、无需耦合剂等优点，受到广大无损检测与评估工作者的广泛关注。
