摘要
用SV4型声速测定仪测声速有三种方法:共振干涉法、相位比较法、时差法.从实验原理、实验仪器、实验操作以及可能的实验误差四方面对三种方法进行比较.
Thereare three ways by using SV4 - detector to test hypersonic speed of sound ： they are resonance interferometry, phase comparative law, and time difference. This paper will be of principle ; experimental apparatus, and the possible operation of the four experimental error to compare these three methods.
