ULTRASONIC wavesNONDESTRUCTIVE testingTHEORY of wave motionDISTILLED waterThe phosphate content of a test sample is one of the indicators of the trophic status of the test water. In this work, an attempt was made to use a non-destructive ultrasonic technique to determine this parameter. ...
Non-contact control of position of a particle using an ultrasonic standing wave field in water has been studied experimentally. Although a standing wave fi... T Kozuka,Toru Tuziuti,H Mitome,... - Ultrasonics Symposium 被引量: 35发表: 1998年 Diffraction of Light by Ultrasonic Waves of Variou...
The propagation speed of ultrasonic waves in rock was measured using oscilloscope and speed device.Effects of composition,porosity,soakage and other characteristics of rock on the ultrasonic propagation were analyzed.Results showed that the propagation speed was mainly determined by the porosity.Meanwhile...

To find the depth of the sea based on the time it takes for a sound pulse to travel to the sea floor and back, we can follow these steps:1. Identify the Given Values: - Speed of sound in water (v) = 1500 m/s - Total time
A pulsed jet was generated by modulating a continuous stream of water with ultrasonic waves. A velocity transformer connected to a transducer was located axially inside a nozzle to induce longitudinal pulsations in the water. An extensiv... MM Vijay,J Foldyna - 《Jet Cutting Technology》 被引...

The ultrasonic wind speed and direction sensor uses the propagation speed of ultrasonic waves in the air to be affected by the air flow to measure wind speed. Compared with conventional anemometers, the biggest feature of this measurement method is that the entire wind measurement system does not...
A method is considered for determining the distance between two wedges and the speed of longitudinal ultrasonic waves in a test object when measuring the profile of the surface of pipelines under the bead of a weld. The method makes it possible to reduce the error in determining the profile of...
