Numerical examples , model tests , and in - situ tests are presented to verify the effectiveness of these methods 文中并以数值算例、模型试验及现场试验验证各种影像法之有效性。
The techniques introduced include the imaging of surface - opening cracks , the three dimensional scan of surface - opening cracks , and the imaging of internal defects using time domain or frequency domain signals 本文介绍数种利用弹性波建构混凝土缺陷影像的技术,包括表面裂缝影像法、表面裂缝三维扫描法,以及时间域和频率域的内部缺陷影像法。
