【Abstract】 An instrument for measuring longitudinal stress of seamless railroad was developed on the basis of Barkhausen effect. The principle of the instrument was introduced. It was found in the in situ test that the longitudinal stress in the fixed region of seamless railroad was in the state of uniform distribution on the whole.更多还原
