摘要
首先分析指出杨氏弹性模量测量作为设计性实验符合设计性实验的选题原则;然后,简介测量金属丝伸长量的几种方案,通过不确定度分析,指出进一步提高杨氏弹性模量测量精度的关键;最后,总结了本设计性实验的意义。
The begining of paper,it analysis obtained that measuring Young＇s modulus as a design experiment is in conformity with the principle of design experiment;and then introduces several programs of measuring wire elongation,through the analysis of uncertainty,points out what＇s the key of further improving measurement accuracy of Young＇s modulus;At last,summed up the significance of this design experiment.
