顺便说说

• Incidentally , with power amplifiers , this ultrasonic energy can cause huge amounts of ultrasonic power to be generated , causing the amplifier to overheat for no apparent reason , sometimes damaging output circuitry or blowing fuses
  顺便说说，对功放而言，这些超声能量能产生巨大的超声功耗，显然这会使功放产生过热的情况，有时会损害输出电路甚至熔断保险。
