The types of impedance transition and of composite resonant are now widely used, but the research in this area is not perfect. in this paper analytical means is used to study absorption coefficient ' s prediction models. diversified cavity structures and material parameters are analyzed in detail in order to the anechoic coalings " acoustical design
現代應用的吸聲層基本是阻抗過渡結構或復合諧振吸聲結構,但我國在這一領域的研究卻不盡如人意,針對水下消聲覆蓋層的吸聲系數預報及聲學設計問題,本論文利用多種解析方法研究聲學模型,並對各種模型的聲腔結構和材料參數做了詳細的分析,為消聲層的聲學設計打下了良好的基礎。The analytical mode is based on the theory of sound propagation in layered media. the concept of equivalent parameters is established. the absorption of sound energy by damping layer ' s is represented by use of complex sound impedance
解析模型以分層介質中的波動理論為基礎,建立了等效參數的概念,並運用聲阻抗的復數表示法把阻尼層對介質層聲能吸收的影響都考慮進去,通過比較敷設消聲覆蓋層前後多層傳遞損失的差異來獲得消聲層的效率。When the acoustic impedance contrast between the thin dipping interface and its adjacent formations exits, their interfaces can be observed from the snapshots, but the acoustic field is rather complex
4 、當傾斜薄夾層的聲阻抗與其鄰層的聲阻抗相差較大時,盡管從波場圖中可以大致看出兩個地層界面的存在,但此時聲場分佈非常復雜。By using these two methods hereinbefore, we have dealt with sound pulse tube data and 200 - set survey data of sea bottoms of five positions. we summarize the results as follows : 1 ) the all of surface layer sediment can be used on the sea bottom classification
利用反演和統計特徵量提取方法,對實驗室聲脈沖管數據和海上實際調查數據( 200組)進行了具體分析處理,得出以下結論: ( 1 )聲阻抗反演方法可以用於表層海底分類。Acoustic impedance layering
