摘要: 根据塞曼效应实验及电子荷质比的计算原理的分析,本文编写了一个处理实验数据的数据库软件,改进了数据处理方法,进行了实际的实验测算.并与采用不同计算方法的南京激光仪器厂所开发的数据处理软件的测算结果进行了对比.结果表明,采用完全相同的多组实验数据,最后的计算结果不论是从精确性还是离散度方面都要优于前者.

Abstract: In the experiment measuring materials of Young's modulus using stretched method, its diametergradually decreases along with the length of it gradually stretches, so one needs to consider this problem. Taking the measurement of Young's modulus of the silica gel as an example, we convert the change of its diameter to its elongation. The experimental results of introducing Poisson's ratio show that the uncertainty decreases and the accuracy is improved.

Key words: stretched method, Young's modulus, Poisson's ratio
