  1. According to their space position, the seismic features of shallow gas in this region can be divided into three groups : ( 1 ) features in the stratum : acoustic blanket, acoustic curtains, acoustic turbidity, irregular strong top reflection boundary, and phase pull - down in both flanks ; ( 2 ) features of the seabed : seabed pockmark and giant sunken pit ; ( 3 ) features in the seawater column : acoustic plumes, cloudy turbidity and point - line - type reflection

    該區的淺層氣地震特徵按空間位置分為3大類: ( 1 )地層中的特徵:聲學空白、聲學幕、聲學擾動、不規則強反射頂界面、兩側相位下拉; ( 2 )海底面的特徵:海底麻坑、大型塌陷坑; ( 3 )海水層中的特徵:聲學羽流、雲狀擾動、點劃線反射。
  2. The gas bubbles affect the acoustic properties of the line by energy dissipation as well as by added compliance.

    氣泡改變了管道的聲學性質,這是由於能量的耗散和增加了順從性的緣故。
  3. The microwave delaylines using hts thin films have the advantages of small size and mass and low insertion lose. these characters are much better than the delaylines using surface acoustic wave, coaxial - line, magetostatic wave or conventional metal planar structures. these merits benefit a lot in largely reduction the mass and volume of communication systems

    利用高溫超導( htsc )薄膜材料研製的微波延遲線具有體積小、重量輕、插損小等優點,這是利用聲表面波、同軸線、靜磁波或常規金屬平面結構設計的延遲線所無法比擬的。這些優點對于減輕通信系統的重量和縮小體積都是非常有利的。
  4. Hands - free speech communication is indispensable in audio and video conference systems, hot - line telephones and videophones, mobile radio terminals, digital isdn network etc. however, the control ( cancellation ) of the acoustic echo has always had a strong impact on the transmission quality in hands - free telecommunication ~ [ 1 - 3 ] conventional methods of acoustic echo control ( cancellation ), such as echo suppression or gain control, may lead to the degradations in speech quality or make the speakers feel uncomfortable

    免提式話音通信在移動電話、熱線電話、車載電話及isdn網的電視電話會議等多種領域正得到日益廣泛的應用。但至今的免提式話音通信中,仍免不了受回聲引起的話音失真、甚至嘯叫等干擾,大大降低了免提話音通信的質量。由於聲回波對消問題尚未得到圓滿解決,實現高質量的免提式話音通信仍是一個極賦挑戰性的課題。
  5. Acoustic delay line storage

    聲延遲線存儲器
  6. On - line inspection and measurement methods of the leakage of valves based on the acoustic emission technology

    基於聲發射技術的閥門泄漏在線檢測方法
