解釋
綱狀裂縫-
The experimental results show that if such technology parameters as the baking speed, wall thickness, and sl pattern thickness are suitable, or the size of sl pattern in one direction gets very small, shell can be prevented from cracking during baking process
研究結果表明：採用樹脂制備方法，不僅可以簡化傳統製作蠟模的工藝步驟，而且大大縮短了製作周期；樹脂模型精度、粗糙度對復雜鑄件的傳遞特性，己成為該方法被廣泛應用的一個重要的前提條件。 -
The main contents are as follows. by the experiments of two joints under low - reversed cyclic loading, the paper analyzes the failure pattern, energy dissipation, ductility and cracking in the joint cores, evaluates the seismic performances and anti - crack behaviors of the joints, and deduces the anti - crack formula of the subassemblage and prestressed frame joint. through the fini te element analysis software ansys, the paper analyzes the specimens nonlinearly, and the theoretical analysis results are well consistent with those of the experiment
主要內容包括：通過兩榀節點在低周反復荷載作用下的試驗，分析其破壞形態、耗能能力、延性性能和節點核芯區裂縫開展情況，評估節點的抗震性能和抗裂能力，推導出預壓裝配式框架節點的抗裂驗算公式；並運用ansys對試驗中的節點進行了非線性分析，計算結果與試驗結果基本吻合。 -
At first, development of various cracks carefully recorded and strains on both the rebars and the stirrups were measured in detail, together with the deflections of the beam. in such a way, correlation between the measured strain profiles of the reinforcement and the observed cracking development of each specimen was pursued. principal factors contributing to the cracking pattern and failure mode were figured out as a result
首先，通過單調靜力加載試驗研究，對梁的裂縫延伸和開展、縱筋應變、箍筋應變、梁的撓度等指標進行了細致的量測，試圖追蹤每一試件在裂縫發展及破壞過程中縱筋應變狀態的變化和裂縫發展程度的相關性，進而總結出有腹筋約束梁裂縫開展及鋼筋應力分佈的一般規律。 -
A major drawback of this kind of rehabilitation is the reflection cracking of the overlay, whereby the cracking pattern existing in the original pavement is extended into and through the new overlays
這種修復方法最主要問題是罩面層的反射裂縫，也就是在原路面中存在的裂縫能夠擴展並延伸到新的罩面層中去。 -
In the paper, on the basis of expounding the importance of similarity theory in the numerical simulation of tectonic stress field, it is pointed out that, only by making the numerical model be similar to the geological prototype in material, combination pattern, boundary condition, loading mode and cracking criterion, etc., may the simulation result be real
摘要論述了在構造應力場模擬中相似性原理的重要性，指出地質原形與數值模型在材料、組合形式、邊界條件、受力方式和破裂準則等方面必須相似，模擬的結果才具有真實性。 -
In order to avoid the shell cracking during baking process of quick investment casting based on stereolithography ( sl ) pattern, an expanding model of sl pattern - ceramic shell is proposed via analyzing the interaction between investment shell and sl pattern, then the cracking condition of investment shell is given
摘要為了解決快速熔模鑄造中型殼開裂問題，對樹脂模型與型殼材料在消失過程中的熱變形機理和型殼開裂條件進行了有限元分析，建立了原型型殼熱變形數學模型，並應用於新型燃氣渦輪導向器的快速鑄造。
