专家解读视频
Specifies a method of determining the total radiated acoustic power of ultrasonic transducers based on the use of a radiation force balance. Establishes general principles for the use of radiation force balances in which an obstacle (target) intercepts the sound field to be measured. Coverage includes: target type, target diameter, transducer positioning, transducer coupling, water contact, environmental conditions, and thermal drifts. Also gives definitions, diagrams and annexes.
