弦线波振动实验的一种新的数据处理方法

A New Method of Treating Data in Chord Vibration Experiments

运用Origin软件对弦线波振动实验的数据进行线性拟合与作图,并与传统的最小二乘法进行数据处理结果进行比较,以验证Origin软件对弦线波振动实验数据处理的可行性.实验表明,通过Origin软件拟合的结果与所作图形均与传统的最小二乘法进行数据处理结果相吻合.利用Origin软件处理数据与作图,简洁、快速、直观、精确,可以在教学过程中应用.

The Origin software is applied in the data treating to line matching and making diagram in chord vibration experiments. The experiment result is subsequently compared with that of data treating by the traditional least square method to test the feasibility of Origin software treating data in chord vibration experiments. As a result,it is suggested that the experiment result chimes in with the results of data treating by the traditional least square method. The experiment is concise, rapid and precise with visual results, thus it can be applied in teaching process.
