摘要
PASCO平台的弦音计实验,将金属弦的振动信号转换成电压信号,并通过计算机软件控制接口实时采集数据,能够探测金属弦的振动情况,并研究波速、弦的线密度以及弦的张力之间的关系。该文比较了基于Pasco平台的两种计算机软件,Data Studio软件与Capstone软件分别弦音计实验中的应用,总结了FFT法、周期法以及数据分析和保存时不同软件的优缺点,为精确测量提供了依据。
The sonometer experiment on PASCO platform converts vibration signals of metal strings into voltage signals and collects data in real time through computer software control interface. It can detect vibration of metal strings and study the relationship between wave velocity, string linear density and string tension. This paper compares the application of two computer software based on PASCO platform, Data Studio software and Capstone software, respectively, in sonometer experiment, summarizes the advantages and disadvantages of FFT method, periodic method and different software for data analysis and storage, which provides a basis for accurate measurement.
