1) echo
[英]['ekəʊ] [美]['ɛko]
回声，回波，反射波
2) echoes
[英]['ekəʊ] [美]['ɛko]
反射回波
1.
In order to detect defects in pipes effectively, by using PZT transducers, which are attached axis-symmetrically around the pipe, to generate and receive ultrasonic guided waves, the relationship between the echo peak-to-peak amplitude of echoes of the pipe end and defect and the exciting frequency was studied.
为了有效地检测管道缺陷,使用PZT传感器在管道中激励并接收超声导波,采用轴对称激励接收的方法,通过多组实验研究了导波在一定频率范围内管道端部与缺陷的第1次反射回波的幅值大小与频率之间的关系,分析了传感器中探头个数对信号大小的影响,确定了激励导波的最佳频率范围。
