Based on the sound velocity measurement from college physics experiments , Origin soltware is usedto make a linear fiting to the data obtained from experimental measurement,and the results are compared withthe traditional suecessive difference method.The sound velocity values obtained by the two methods are almostidentical.The results indieate that introducing Origin software to process experimental data in experimentalteaching is more convenient and elficient, and can effectively improve experimental efficiency and accuracy,avoiding errors caused by human faetors.
