| 摘 要： | 本文通过对大量实验数据进行分析,同时采用MATLAB软件对数据进行系统处理,作出了数据间的关系图。借助软件使物理分析简单化,形象化,进而使实验者有更多的精力关注其内在的物理思想。并在此基础上,分析总结出弦振动形成驻波时波长与张力以及波长与振动频率的规律,提出检验判断实验数据的方法,可以使实验者在做实验的过程中随时判断数据的正确与否。

| Abstract: | In this paper,MATLAB software system is used to process a large number of experimental data. The physical analysis becomes simple and visual by means of this software, thus it can make ex- perimenters pay more attention on the inner physical thought. Furthermore,the law of the wavelength and tension and the law of the wavelength and frequency are analyzed and summarized. The method to judge the validity of experimental data is putforward, which can help experimenters to judge the data in the process of conducting experiments at any time. |
