| By analyzing the characteristics of ultrasonic whichspreads through multilayer medium and the attenuation ruleof ultrasonic signal in material , relative attenuationcoefficient" model is established in this paperOn the basis of the model , the ultrasonic testinginformation processing system "UTIPS" is developed, usingobject-oriented programming and Visual Basic 5.0. Thefunctions of data conveying , data storage , automaticgrading , graphic displaying and result printing areintegrated in the software. It not only realizes intelligentprocessing of ultrasonic testing signals , but also greatlyincrease the precision , which lay a fundation of therealization of ultrasonic testing modernization... |
