  1. The research of acoustic wave in different - section resonance pipe

    變截面共振管的聲特性研究
  2. It utilizes two boltclamped langevin transducers with unanimous frequency characteristic which convert vertical vibration to flexural traveling wave. they are arranged on the place of a elastic pipe to generated traveling - wave. when the traveling - wave propagate, the particles on the elastic pipe traverse an elliptic trajectory, materiel is transported by friction or acoustic streaming

    利用兩套頻率特性一致並以縱向振動方式工作的夾心式換能器，通過合理的布局在導管中激勵出行波，使輸送管管壁質點產生橢圓運動，從而利用摩擦或在液體中產生聲流來實現固體及液體的傳送。
  3. Precise locating needs to detect the acoustic signal of the pipe leaks that has close relationship with the acoustic impedance of the leaks

    準確定位漏點須對漏損管道的聲信號進行研究，而漏損管道的聲信號與漏損點的聲阻抗密切相關。
  4. Acoustic transmission matrix of reactive muffler containing units made of perforated pipe

    抗性消聲器中含穿孔管時的聲傳遞矩陣
  5. The impact on the muffler performance is realized by the high - speed pulsation gas flow, which regenerates noises and strikes the acoustic elements of the muffler such as the pipe run, the body case and the separator plate to arouse the vibration radiated noise

    氣流影響消聲器性能的主要原因是發動機排氣的高速脈動氣流再生噪聲，其次是這種氣流會沖擊消聲器的管路、殼體、隔板等聲學元件，進而激發振動輻射噪聲。
  6. The main work in this paper is as follows : designed and set up a system of acoustic emission ( ae ) pipe testing, include pipe leak simulated equipment and acoustic emission testing equipment

    具體包括以下工作： 1建立了一套充液管道泄漏聲發射檢測系統，包括管道泄漏模型和聲發射檢測裝置兩部分。
  7. In this paper, leak of water - filled pipe was researched in laboratory by means of modal acoustic emission and modem signal processing technologies

    本文在實驗室條件下，利用模態聲發射技術並結合現代信號處理技術，對充液管道泄漏問題進行了研究。
  8. Through redesigning of pipe system to alter its character and using the ways to isolate vibration and reduce vibration, it is yielded very good results of reducing the vibration and noise. in some points the acoustic pressure level drops very much, such as in the standard point of number one pump the acoustic pressure level drops 15db ( a ) and in the standard point of cistern also drops 15db ( a ), and in the highest point of the acoustic pressure before redesign drops from 105db ( a ) to 44db ( a ), and in the second floor the acoustic pressure level have reached the requirment

    通過對管道結構的改造，減振和隔振措施的有效使用，使供水系統的振動和噪聲得到了有效的控制：使一號泵前的標準點和蓄水池前標準點的噪聲聲壓級都降低了15db （ a ） ，管道上測點的振動量降低了90 ；二樓居民門外的噪聲從55db （ a ）降到25db （ a ） ，遠低國家標準35db （ a ） ；在改造前噪聲最大點西側蓄水池的噪聲也由105db （ a ）降到44db （ a ） 。
