  • Online:2011-01-25 Published:2011-01-20

摘要: 通过对传统实验仪器的稍加改造,利用PASCO科学工作室平台分别进行了超声波在气体和液体中传播速度的测量实验,使实验操作更加简便,数据处理更加快捷.结果表明:实验测量值非常接近公认值.

关键词: 超声波, 声速, PASCO

Abstract: By both slight improvement of traditional experimental instruments and the platform of PASCO science workshop,the respective experiments of ultrasonic velocity measurement in the media of gas and liquid can be carried out more conveniently and statistics can be obtained with more accuracy.It is shown that the measured values are quite close to the widely accepted ones.

Key words: ultrasound, velocity of sound, PASCO
