用弦振动做总结经验公式的实验

Test of Chord Vibration as a Summing-up Epirio-formula

普通物理实验项目选题中 ,总结物理规律的实验课题甚少 .笔者经多年教学实践 ,开设《总结弦振动的经验公式》的实验 .该实验具有器材简单、操作方便、现象明晰、系统误差小等特点 .本文在对实验原理作简介的基础上 ,给出了实验材料———弦线 (即漆包线 )的规格数量 ;列出一组实测数据 ,并进行数据处理 。

On the basis of a brief introduction of the test of chord vibration as a summing-up epirio-formula,this artide supports some experimental materials,practically examined data and simaltaneously deals with the data as well as analizes & probes into the crux of the text.
