samdwich meaning in Chinese
夹层
Examples
- It showed the performance of anti - aging is good . the modified asphalt may be looked upon materials for highway road . the undee samdwich of the modified asphalt was characterized by sem
通过扫描电子显微镜( sem )分析表明改性后沥青呈波浪形层状结构，这一结构的形成同时改善了改性沥青的高低温性能。 - The performance of high and low temperature was improved simultaneity because the materials of modified asphalt had structure of the undee samdwich . the modified asphalt was characterized by element analysis , tem , xrd , tg and ft - ir . we discussed the possible mechanism of the modification
另外，还采用了透射电子显微镜( tem ) 、 x射线衍射( xrd ) 、热重摘要分析( tg ) 、红外光谱分析( ft - ir )等分析方法对改性沥青进行了表征，探讨了可能的改性机理。 - In the paper , other research results are summarized , and a big test model indoor of row pile retaining and protecting deep foundation pit is designed . for homogeneous soil or samdwich soil structure three different retaining and protecting kinds : dense pile , thin pile and without pile are designed , using excavation simulation and loading on the top of slope , the model test is divided into two stages : foundation pit excavation simulation stage and destroy test stage . in this paper , for three different retaining and protecting kinds , the relation between soil pressure and displacement of piles , the relation between soil stress and strain , interaction of pile and soil and retaining and protecting loss - stability destroy are systemic studied
本文总结了前人研究成果，构筑大型室内深基坑排桩支护试验模型，在均质及层状土层结构地基上，设计了密排桩、疏排桩及无支护三种不同支护型式，采用模拟开挖与坡顶均布加荷方式，进行了模拟基坑开挖和破坏性的两个阶段试验，对三种不同支护型式的土压力与桩位移、土体应力与变形、桩土共同作用及支护结构失稳破坏进行系统研究。 - This paper chose the important part of environment field , namely temperature field as research object , looking pavement structure as samdwich , according to heat conduction theory deduce the analytic solution of one dimension unstable state temperature field modified by year temperature of pavement structure in natural environment , tested by practically measure , the analytic solution of temperature field accords with the temperature distributing law of pavement structure
道路环境场研究是路面长期性能研究的重要组成部分和基础。本文选择道路环境场中最主要组成部分? ?温度场为研究对象，视路面结构为层状体系，根据传热学原理推导出自然环境下经过年温度修正的以天为周期的道路结构?维非稳态温度场解析解，经过实测验证，符合道路结构的温度分布规律。
