摘要
本文根据超声学原理 ,设计制作了超声波传感器 ,研究了酵母液中超声波传播时间与浓度以及温度之间的关系 ,并对测量中产生影响的各个因素分别加以讨论 。
The ultrasonic sensor is designed according to the requirement of the acoustic theory.The linearity relationship among spread time,concentration and temperature has been established through experiment.Several factors to influence the result of measurement are discussed that will lay the foundation of the application of the ultrasonic sensor to very complicated conditions.
