摘要
本文提出驻波管测量声速的新方法,通过对实验原理的分析,给出了驻波管测量声速的方法和实验数据.应用驻波管测量声速,不仅理论依据充实,方法简单易行,而且可进行多个不同频率的测量,并且在拓展学生知识面的同时,还培养了学生对知识的应用能力.
This paper put forward the new method of measuring sound velocity using standing wave tube, through the analysis of the experimental principle, gives the method of standing wave tube measuring sound velocity and the experimental data. It is shows that the standing-wave tube measuring sound velocity, not only the theory basis is enrich and method is simple, but also can measure a number of different frequency. It also can expand the students knowledge when cultivate the students＇ ability to use knowledge.
