超声表面波 meaning in English

ultrasonic surface wave

Experimental study on the metal material surface stress measurement using surface wave technique
超声表面波检测金属材料表面应力的实验研究
In view of the requirement of stress testing in the engineering practice , based on the achievement in ultrasonic ndt and visc , this dissertation investigates the detection of surface stress in several typical components using surface wave acoustoelasticity and its visual expression using visc technology . the nonfiguratived data experimentally or theoretically obtained are converted to visual and idiographic figures , which are easy to understand and analyse
本文针对工程实际中对构件应力检测的需求，结合国内外超声检测技术和科学计算可视化技术的发展趋势，利用超声表面波声弹性方法检测典型构件表面的应力分布状况，并借助计算机可视化技术把应力场分布状况表示出来，将抽象的数据场转换为形象、具体的图形，便于理解、分析和评价。
