摘要
从曲面构件超声无损检测的原理出发 ,针对非对称曲面型构件超声检测比较困难的特点 ,分析了非对称曲面型构件自动化超声检测的原理 。
The theory was analyzed of the ultrasonic inspection about the curved surface.One algorithm method which based on least square method was presented,which adjust the plus of sensitivity to deal with the difficulties of the ultrasonic inspection on the curved surface.
