摘要
随着新材料不断涌现及现代工业对构件质量要求的提高 ,超声检测技术得到了较大发展。综述近年来国内外在超声导波技术、声发射新技术、新型超声非接触换能方法、超声信号处理与模式识别等方面的若干研究成果 ,这些超声检测新成果既有学术前沿性 ,又有一定应用背景。
With the uninterrupted emergence of new materials and the requirements of modern industry for the qualities of components, a considerable development has been got on ultrasonic testing techniques. The achievements obtained in research home and abroad last several years are reviewed, including ultrasonic guided wave technique, advanced technology of acoustic emission, ultrasonic non contact coupling method, ultrasonic signal processing and pattern recognition. The achievements have not only academic forward positions, but also backgrounds of applications.
