- In this paper,a method for measuring acoustic power of plane piston transducer based on calorimetry is presented.
- A maximum acoustic power 43.1 W output to RC load of 110 cm~3 capacitance was measured with helium filling of 2.1 MPa and heating power of 2 000 W.
- A thermoacoustic engine converts thermal energy into acoustic power by thermoacoustic effect without any mechanical moving parts.
- The king was shorn of his power by his nobles.
- Acoustic power and ultrasonic frequency are both important factors of the degradation of paper mill wastewater ultrasound.
声功率及声频率对造纸黑液的超声降解均有影响。 (5) 超声时向溶液中通入不同溶解气体均能提高超声辐射的效果。
