    有關混凝土力學特性的力學模型都是基於混凝土材料的宏觀層次研究其力學特性，其主要特點是把材料理想化為均質材料進行研究，把實驗室尺度下力學試驗的結果作為材料的力學參數，以此為基礎進行更大尺度宏觀結構的力學響應分析。
  3. The strength is a main mechanics performance index of the concrete. it has always been a focus of material scientific research of concrete. models about mechanics characteristic of concrete were mostly the understanding based on material macroscopical level of concrete in the past. its main characteristic turns the material ideal with heterogeneous, nonuniform nature into the even, continuous body and carry on modeling. this kind simplified and met project practice ' s demands to a certain extent, but it is difficult to study the influence produced toward strength of material of structure of the microcosmic or the mescoscopic within the concrete material with this kind of method

    以往有關混凝土力學特性的模型大多是基於混凝土材料宏觀層次的認識，其主要特點是把具有多相、非均勻性質的材料理想化為均勻、連續體進行建模，這種簡化盡管在一定程度上滿足了工程實踐的需要，卻難以用這種方法來研究混凝土材料內部微觀或細觀結構對材料強度所產生的影響，不能說明材料內部結構如孔結構變化時強度的變化規律，也不能用於指導如何改進材料的組成和微觀結構而達到提高混凝土強度的目的。
  4.

    第四章以鐵電體1800疇變的過程中形核規律和疇界運動規律的實驗觀察結果為基礎，根據熱力學理論建立鐵電體疇變的理論框架和數值模擬方法；給出了單疇內疇變驅動力、新疇形核準則、疇界運動速度公式、疇變動力學的表達式，單晶的疇變速率公式；用細觀力學的觀點給出了對多晶鐵電體多場耦合的有效性質進行包含疇變速率影響的多尺度分析方法。
  5. First, to solve the present difficulties in steel - concrete engineering structural analysis and construction supervision and control, steel - concrete coordinating relations for two kinds of heterogeneous material composite members, prestressing cables and concrete, steel tubes and concrete, are studied and deduced by proposing the concepts of both composite members of heterogeneous materials and steel - concrete coordinating relations

    首先，針對鋼混工程結構分析和施工監控中存在的一些難題，在提出鋼混異種材料組合構件和鋼混協作關系概念的基礎上，研究並推導了預應力鋼索與混凝土、鋼管與混凝土兩種異種材料組合構件的鋼混協作關系。
