Through systematically analyzing the composition and structure of concrete from three levels of macroscopic, microcosmic and ultra - microcosmic, the author of this paper found that the mechanical properties and durability of concrete depended on mainly its composition and structure. the interface, which is one of three composition of concrete ( hardened cement paste, aggregate and interface ), is the most weak zone in concrete
作者通過對混凝土材料的組成和結構進行宏觀、微觀和細觀三個層次的系統分析發現,混凝土材料的力學性能和耐久性主要取決于其微觀的組織構成;在組成混凝土材料的三相(硬化水泥漿體、集料和硬化水泥漿體-集料界面過渡區)中,界面過渡區是其中最薄弱的一環。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。
