【Abstract】 The relation of crack width and the magnetic memory signal is studied.Through the examination experiment on four tube pieces’ crack part,the relation of crack width,the maximum of leaking magnetic field and differential coefficient K is found out.When the crack width increases,the K rises too.更多还原
