As one of the most important discussions in this paper , the theoretic discourse of vegetable - gum drilling fluids includes the following information : analyzing the physical and chemical properties of vegetable gums to show their workability and superiority in geological drilling materials ; synthetic high polymers and base modifiers , or coupling agents , which are indispensable for vegetable - gum drilling fluids , can optimize their behaviours . the modifying mechanism of these constituents is also presented as the references for the coming laboratory tests 本文首先通过对植物胶物理性质和化学性质的探讨，从物质理论上证明植物胶冲洗液用于地质钻探的可行性和优越性；随后，又分析证明了合成高分子聚合物和碱激发(或偶联剂)的改性处理方案是植物胶冲洗液研究必不可少的技术路线，两者对于植物胶冲洗液性能的优化起着至关重要的作用，本文还就它们对于植物胶液的改性机理做了详细的探讨。
Many experimental researches have been done and given preliminary discuss on the bond and mechanism . meanwhile , proper bond materials and better proportion are offered , under the background of the difference interfacial bond methods and curing systems . this paper also makes a compare on the bond effect of various bond materials and given reference for the project application and the future research of bond mechanics and endurance 针对这一问题，本文在大量实验的基础上，对不同种类材料的界面粘结效果和影响因素进行了实验研究，对其粘结及改性机理进行了初步探讨；提出了不同界面粘结方法、不同养护制度下适宜的界面粘结材料及其较佳配比；对不同界面粘结材料在新老砂浆及新老混凝土中的粘结效果进行了对比，为其工程应用及界面粘结力学、耐久性能等的进一步研究奠定了基础。
The newest preparations and characterization of epoxy resin composites modified by nano montmorillonite ( mmt ) were reviewed in the paper , the outstanding properties and the toughening and reinforcing mechanisms were investigated and application prospects of the materials was also evaluated with 27 refs 摘要综述了目前环氧树脂黏土纳米复合材料的制备方法和表征手段，介绍了环氧树脂黏土纳米复合材料的优异性能，并对其增韧增强改性机理作了探讨，最后展望了环氧树脂黏土纳米复合材料的应用前景。
Effect law of different materials on the properties of structural adhesive were studied and the modifying mechanism was discussed by microcosmic testing method . results showed that , when nanosize sio _ 2 dispersed in the epoxy base , effect of nanosize sio _ 2 on working performance was changed obviously , on bond strength , impact strength and heat distortion property were good 论文通过纳米二氧化硅、纳米碳酸钙和有机蒙脱土三种纳米材料对常用的环氧树脂建筑结构胶进行改性,研究了不同纳米材料对结构胶的性能的影响规律并通过微观测试手段对其改性机理进行了探讨。
The absorption is ascribe to physical absorption . silane combines with h of hydroxyl on surface of sericite , the absorption is ascribe to chemical absorption . in silane and stearic acid cooperation modification , c = o absorption peak appears in spectrum and the regional vibration of si - o - si becomes wide , which shows the physical absorption of stearic acid and chemical absorption of silane produce an effect on surface of sericite 采用红外光谱对绢云母改性机理进行分析，结果表明，硬脂酸改性绢云母吸附强度较弱，容易脱附，以物理吸附为主；硅烷改性绢云母，与绢云母表面的羟基形成氢键，以化学吸附为主；硅烷与硬脂酸复合改性，其光谱中出现了c = o键特征吸收峰，并且si ? o 、 si ? o ? si振动吸收区变宽表明复合偶联剂在绢云母表面既有硬脂酸的物理吸附，又有硅烷的化学吸附。
The modified asphalt may be looked upon materials for highway road . the sea and island structure which the island lied in the sea and the sea lied in the island of the modified asphalt was characterized by sem . the modified asphalt was characterized by element analysis , tem , afm , gpc , tg and ft - ir 通过扫描电子显微镜( sem )分析表明改性后沥青呈岛中有海、海中有岛的海岛结构；另外，还采用了元素分析、透射电子显微镜( tem ) 、原子力显微镜( afm ) 、凝胶色谱( gpc ) 、热重分析( 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。
