例句與用法
- Finally finding that there are two reasons that cause vibration of pipe and noise . the one is the vibration of pump which transfers to pipe and stimulates the vibration of pipe . the second is the stimulating frequency of pulsating water is coherent with the natural frequency of pipe
最后得出管道的振動主要是由于兩個原因，一是泵的機械振動傳遞給管道，引起管道的振動；二是由于水流的脈動激勵頻率與系統(tǒng)的固有頻率相吻合，引起管道的共振發(fā)聲。 - So the pipe system sends out noise because of resonance . especially the frequency 250hz of pulsating water is in close proximity to natural frequency of pipe , so the 250hz is a dangerous frequency to the pipe system . there is another reason why the noise is reached to 110db ( a ) in pump room that the noise is magnified by the cistern because of the resonance of cistern
特別是激勵頻率為250hz的頻率分量恰好與管道系統(tǒng)的固有頻率相接近，其引起的管道振動對噪聲的貢獻最突出，同時也與水泵房房腔的固有頻率相接近，從而引起房腔共鳴發(fā)聲，使噪聲進一步被放大，以至于噪聲最大處高達105db ( a ) 。
