摘要
弦振动实验是普通物理实验之一。通过实验装置的改进探究弦长振动的波长与弦上张力关系。同时采用origin软件和最小二乘法处理实验数据。结果表明改进后的实验装置能有效的提高实验的精确性,同时操作简单。
The experiment of vibration string was the general physics experiment.It was explored the wavelength of vibration chord length and string tension through the experiment device was adapted.At the same time the data was processed by origin software and least-square method.The results were showed that the modified experimental device can effectively improve the precision of the experiment and the operating was simple.
