Abstract: The adjustment difficulties for the Young＇ s modulus experiment are pointed out, and the difficult reasons are analyzed by using theory into practice. A new simple adjusting method is proposed, i. e. , the insert target method. The problems of aiming at and focusing on are solved effectively. A complete flow chart of the method is given and its implementation plan is also introduced.
