acoustic power output的用法和样例：
- It was experimentally proved for the first time that the maximum acoustic power output can be transferred to the load when the acoustic resistance of RC load equals to its acoustic capacitance impedance.
- After acoustic power output of the thermoacoustic engine was measured accurately by variable-load method,the mutual relations of power output with pressure ratio,heating power and heating temperature were analyzed.
- A formula for calculating power output is derived.
- 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.
