摘　　要：杨氏模量测定是物理实验教学中的一个重要实验,针对实验中存在的误差来源及减少误差的办法进行深入分析.通过理论分析和实验验证,测定的杨氏模量实验数据精度明显改善.Measurement of Young＇ s modulus is an important experiment in physics teaching. Based on the research and analysis to the sources of error and the methods of reducing error, this paper affords the methods to measurement of Young＇ s modulus that can improve significantly the accuracy of experimental data.
