| 摘 要： | 针对共振法测量杨氏模量实验中存在精确度和获取共振频率上的不足,在原装置中增加高度调节装置和水平仪,通过实验操作对共振阶数进行判断.实验结果证明选用共振二阶型态测量杨氏模量较有优势.

| Abstract: | The uncertainty of accuracy and the shortcoming of obtaining resonance frequency during the experiment of measuring Young modulus by resonance method were indicated.The height addustment device and the gradienter were added,and the resonance order was decided by the experiment.The experiment result proved the second resonance order had advantage in measuring the Young modulus. |
