acoustic pressure wave的用法和样例：
- Methods A hydrophone was used as energy converting equipment to collect wave of acoustic pressure in the field of ultrasound.
- The relationships between oscillation frequency, pressure wave amplitude (ratio) and the size (length and diameter) of the acoustic amplifier are obtained.
- By measuring the acoustic pressure at two points along the tube, the standing wave sound field in the resonator could be separated into incident and reflected components.
- The output signal from the interferometer is proportional to the acoustic pressure in water.
- Experiments indicate that our contrast technique is not sensitive to contrast dose, flow rate, acoustic pressure.
