Mass fluxMass transferDiffusion is the transport of material due to concentration gradients or more precisely due to gradients in the chemical potential. Mass transfer is commonly described as diffusional phenomena in the presence of convective motion. Diffusion and mass transfer play a significant role...
化工原理 Principles of Chemical Industry Principles of Diffusion and Mass Transfer Between Phases 1.THEORY OF DIFFUSION ? Diffusion is the movement, under the influence of a physical stimulus, of an individual component through a mixture ? The most common cause of diffusion is a concentration ...

Retaining the trademark enthusiastic style, the broad coverage now extends to biology and medicine.This overview of diffusion and separation processes brings unsurpassed clarity to this complex topic. For students, Diffusion goes from the basics of mass transfer and diffusion itself, with strong support...
Diffusionanddispersionare different modes of mass transfer in that the mechanisms behind them are ...
Two stirred transfer cells were used for studying the rate of mass transfer across an interface between two liquid phases, in order to investigate the influence of molecular diffusion on the mass transfer. The systems ethyl acetate-water and n-butanol-water at 25 °C provided a wide range of...
所谓的dispersion其实就是流动的流体因为速度不均匀而引起一种对溶质扩散（分子扩散 Molecular Diffusion）...

aInternal and External Mass Transfer. Mass transfer by passive diffusion inside the activated sludge floc (internal)as well as across the laminar boundary layer on the floc surface(external) may be relevant to substances that are degraded inside the floc or on its surface. 正在翻译,请等待...[...
aThe A term contribution in HPLC can be divided into the contribution of eddy diffusion and that of slow mass transfer in the mobile phase (eq 2). A期限贡献在高性能液体色谱在流动相(eq 2)可以被划分成漩涡扩散的贡献和那缓慢的质量传递。[translate]...
