  1. Anechoic coatings " efficiency is getted from its front and back many layer ' s transfer loss compared. first, absorptive characteristic of homogeneous material is analyzed thoroughly. then wkb perturbation means are used to calculate absorption coefficient of the impedance transition structure in this paper

    本論文首先對均勻材料的吸聲特性做了深入的分析，並詳細討論了wkb微擾攝動法，利用wkb方法計算阻抗過渡結構的吸聲系數。
  2. 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。
  3. Above all, we introduce the development of millimeter - wave power combiner and the novel study production at home and abroad. taking circuit form into consideration in the design of millimeter - wave power combiner, the gauge of high reliability and high performance must be defined. we design two kinds of waveguide - to - microstrip transition, the first kind of transition based on the achievement of a matched impedance probe show excellent performance, the second transition can also have good performance on some conditions through numerical simulation

    介紹了國內外毫米波功率合成的發展狀況和最新的研究成果。考慮擬以電路合成方式做毫米波功率合成器，必須解決與功率合成有關的相關組件的高可靠高性能指標問題，因此設計了兩種波導微帶過渡結構，其中探針式過渡測試達到了較好的效果，並對所提出的一種新型微帶波導過渡進行了模擬，在一定條件下具有較好的性能。
  4. The physical process of generating quasi - isentropic compression on target via flier - plates with graded wave impedance might be considered as the successive overlap of a series of small shock loading waves generated by the transition layers in the flier - plate. as a result, the p - v curve of the target was a quasi - isentropic compression curve, which consisted of small hugoniot curves ( similar to isentropic curves ) from different original states, and was located between the hungoniot curve and isentropic curve but closer to the latter

    波阻抗梯度飛片對靶板的壓縮過程是一系列弱沖擊加載波相繼發生作用疊加的結果，靶板由此獲得的p - v線是一組通過不同起始狀態點的hugoniot線的連線，這條連線可以近似看作是由小段小段等熵線連接而成的準等熵線。
  5. The formation of self - assembled interfacial n - dodecanethiol monolayer and its effect on the corrosion protection of epoxy coating were evaluated using the x - ray photoelectronic spectroscopy, electrochemical impedance spectroscopy, impedance - time transition, and phase angle - time transition method

    採用x射線光電子能譜、電化學阻抗譜、阻抗時間譜和相位角時間譜等方法對硫醇自組裝界面層及其對塗層腐蝕防護性能的影響進行了研究。
