| Abstract: | The principles and the applications of the ultrasonic measuring velocity and the ultrasonic measuring distance were presented. Some components were made according to the above principles and applications. The data including the time delays, distances and the frequency shifts on the principles and applications were measured through the data collection system. The results about the sound velocity, the theory distance and the relative velocity were given and the errors were analyzed. |
