摘要
Abstract
It is sensitive for specimen thickness and sensor lift‐off effect to the pulsed eddy current thickness measure‐ment signal of ferromagnetic materials .That causes difficulties to the extraction of wall thickness quantities .In order to e‐liminate the lift‐off effect ,the signal processing method is proposed based on the calculated relative flux .The results show that the relative flux method is not sensitive to the lift‐off effect and the signal processing results is related only to the speci‐men thickness .关键词
