摘　　要：提出一种基于MATLAB软件的空气中声速测量实验仿真及测量数据自动处理系统。该系统以声波在空气中传播时的波动特性为基础,应用MATLAB GUI构建了测量过程动态仿真系统和数据处理系统,实现了相位法和双踪法测量过程的动态仿真,以及四种不同测量方法测量数据和不确定度的自动计算,得到了完整的实验结果。An approach of experimental data automatic processing and simulation of sound velocity measurement is proposed based on MATLAB GUI.In this approach,dynamic simulation system and experimental data processing system is developed by using the wave character of sound and the combination of MATLAB GUI.The dynamic simulation of sound velocity measurement process of phase method and dual trace method is implementation.And then,automatic calculation of measurement data uncertainty is carried out.
