【摘要】 指出了国外(日本)测量杨氏模量常用的一种方法———舌簧片振动法的一些不足之处。针对这些不足,在原实验原理的基础上,对边界条件作了修改,同时引入单片机和光电系统,设计出一种杨氏模量智能测量系统。更多还原

【Abstract】 The flaws of a frequently-applied method used by overseas(Japan)measuring Young’s Modulus,which is the method of vibration reed have been pointed out.Targeting on the these flaws,based on original experiment,we make amendment on the marginal conditions,as well as import single-chip microcomputer and electric-light system,and develop a Young’s Modulus Intelligent Measuring System.更多还原
