应用共振干涉测量法测定空气中的声速,相同条件下多台仪器重复测量实验,对实验结果进行数据处理和误差分析表明：对于某些声速测量仪,当换能器之间的距离小于10毫米时,在移动换能器测量声速的过程中出现了假峰现象,它对实验测量结果造成了很大影响。当使两换能器之间的距离大于10毫米开始测量,可以避免假象对测量结果的影响。

The detailed data processing and error analysis to the results of experiments,applying Resonate Interference Law to measure the sound speed in the air under same conditions repeatedly,show that the results of some Velocity Measuring Instruments come out false peak appearance when moving the transducer from 0 mm to 10mm;it influences the correctness of the experiments.This paper suggests that it can avoid false appearance to start measuring the sound speed when the transducer passes the point of 10mm.
