查询词典 sedimentate

The traditional smoke theory considers that the smoke particles will sedimentate due to gravity after forming of smoke screen, and then the particles reach a final sedimentation velocity thanks to the effect of air-resistance and buoyancy, and the equation can be solved by the Stokes pellet resistance theory and often used to analyze the performance of smoke.

传统烟幕理论认为，在烟幕形成后，烟幕微粒受到重力的作用开始沉降，同时受到空气阻力和浮力的作用，最后使烟幕微粒达到终端沉降速度，这个速度方程可以通过Stokes圆球阻力理论求得，并被用来分析烟幕的性能。

Finally, the article discussed the possible mechanism of multi-phase electrochemical degradation of wastewater through the XPS spectrum of the used catalysts surface: In the acid solutions, the electro-generated O_2 may get electrons on the porous graphite cathode and then form H_2O_2, H_2O_2 may diffused to the surface of catalyst and reacted with its active part to produce OH, which in turn can destruct organics. The catalyst functioned as both the catalyst to decompose H_2O_2 and the flocculants to sedimentate the degraded waste.

最后全文结合研究反应后催化剂表面的XPS光电子能谱推断了该体系降解污废水可能的反应机理：在酸性条件下，石墨双阳极产生的O_2被多孔扩散性石墨阴极还原成H_2O_2，并通过扩散传质作用在催化剂的表面活性中心分解为强氧化性中间产物·OH，强氧化性攻击有机物，使其降解为小分子有机物或CO_2和H_2O，催化剂在体系中即起催化作用也起吸附、絮凝作用。
