【Abstract】 In the measurement of thick and fine steel wire of the Young’s modulus by CCD elongation method Young’s modulus experiment apparatus,the thick steel wire of Young’s modulus values is great different from the standard value.In order to identify experiment error reason and get the solutions to those problems,the experiments is repeated and the results are analyzed,and the prime scheme is brought forward.更多还原
