摘　　要： 声速测定实验中数据处理方法包括直射式时差法、驻波共振法和相位比较法,文章介绍了用这3种方法处理数据的详细步骤和细节,从数字最细小的环节体现数据处理方法的艺术性,包括不确定度、分量、结果表达式等,处处都要求完美、准确。文章用作者实验得出的数据作实例,可供学生参考,以便撰写出完整的、合格的实验报告。也可供实验指导教师参考,考查学生的数据处理能力。 The Determining the velocity of sound of data processing methods Includes the method of in-line time difference, Standing Wave resonance and phase comparison. This article detailed the three steps of processing data and details , From the small link of areas reflects the artistry of the data-processing methods, Including the uncertainty, weight, the results of expression and so on are all perfect and precise requirements. In this paper, the author personally came to the experimental data for example, are available to students in order to write a complete and qualified experimental report. Experiments are also available for reference guide teachers, students examine the data-processing capacity.

关 键 词： 数据处理 时差法 驻波共振法 相位比较法
