表面反应 meaning in English
surface reaction
surfacereaction
Examples
- The surface reactivity of many nonblack fillers generally precludes strong bonding with this type of matrix .
许多非碳黑填料的表面反应性一般阻碍与该种基质形成牢固的粘结。 - A study on electrochemical corrosion of surface reaction of pyrite in high alkali environment
高碱环境中黄铁矿表面反应的腐蚀电化学研究 - In the test , an impact is applied on the surface of the concrete structure , and the response of the concrete due to the impact is measured and recorded
在弹性波试验中，利用钢珠或铁槌敲击混凝土表面，以产生应力波源，并以感测器测量混凝土表面反应。 - Xrd and sem analysis showed that the main composition of the white substance which formed in cracks is caco3 , which can block cracks and is probably the main cause of self - sealing . two processes which called surface reaction process and diffuse reaction process are defined in the formation process of caco3 . the phenomenons in self - sealing experiment can be explained by those two processes
对试件裂缝中沉积的白色物质做sem 、 xrd分析得出其成份主要为caco _ 3 ， caco _ 3堵塞裂缝应该是引起自愈现象的主要原因； caco _ 3的生成包括表面反应和扩散反应两个阶段，这在一定程度上解释了自愈现象先快后慢和自愈幅度砂浆混凝土净浆。 - Based on the analysis of gas - solid multiphase catalytic reaction , the chemical reaction model is established . when the reaction is controlled by the chemical dynamic , the reaction rate is introduced by consideration of the adsorption and desorption effects . when the reaction is controlled by mass transfer , the diffusion coefficient is established which can present the flow rate increases in small reynolds domain ; for the internal diffusion , the internal diffusion coefficient is derived , and then the internal diffusion is coupled with chemical reaction to represent the phenomenon that the diffusion and the chemical reaction occur cocurrently
本文在考虑催化转化器载体内发生的传热传质现象的基础上,建立了催化转化器的一维单孔道和三维多孔道传热传质模型;在分析载体内以气-固多相催化反应为特点的工作机理的基础上,建立了催化转化器的化学反应模型:当催化转化处于化学动力学控制区时,引入了考虑吸附、表面反应和脱附的表面化学反应速率公式,当催化转化处于质量输运控制区时,引入了决定外扩散能力的扩散系数公式和和决定内扩散速率的内扩散系数公式,并与化学反应速率相耦合,得出由扩散过程决定的化学反应速率公式。
