摘要
声学测温是一种先进的温度测量方法,与传统方法相比,具有很多优势。而在声学测温的各种方法中,基于声波传播时间的声速测温方法又是一种比较好的、应用更广泛的方法。本文着重对气体介质中声速测温的两类测量方法进行了研究和比较,分析了其各自的优势与不足。结果表明,直接传播测量方法是一种更有潜力、应用更广泛的测温方法。
The acoustic thermometry has many advantages,compared with conventional methods of temperature measurements.It is an advanced technology. In all these methods, acoustic velocity therrnometry based on the acoustic travel time is a better one with a wider use.Tiffs paper emphasized on the investigation and comparison of two different methods of acoustic velocity thermometry in gas medium, as well as an analysis of their advantages and disadvantages respectively.The result demonstrates that the direct propagation measurement is a better method with much more potential as well as a wider apphcation.
