Following, a experiment has been carried out, the incident waves with a frequency band of 200kHz-3 50kHz are used to the experiment, and a series of peak value-time curves are drawn each 10kHz, corresponding time are found through fitting peak value, thus the position of the defect is calculated accurately. The application of awl-shaped sensor head in the heat change water pipe experiment indicates that the ultrasonic guided waves may transmit nearly 50 meters in the pipe, which is not influenced by the elbows and makes it possible to test defects in long distance and large-scale. The water-load pipe experiment indicates that the displace and energy maybe leakage at the near-surface, which is significant for the further research.

而后，采用200kHz至350kHz频段的入射波进行了实验验证，并每隔10kHz绘出一条峰值一时间的曲线，通过拟合峰值点，找到对应的时间，从而准确的计算出了缺陷的所在；应用锥形探头的热交换水管的实验表明，超声导波可以在管道中传播了近50米的距离，且不受弯头的影响，从而使得长范围、大规模检测成为可能，水载管实验说明了离面位移和能量可能会发生泄漏的特性，为导波的深入研究和应用作了铺垫。
