Self-DiffusionTracer DiffusionDiffusion is governed by Fick's laws. Fick's first law, also known as the "flux equation," describes the flux of matter resulting from a given concentration gradient and diffusion coefficient. The concentration gradient is the thermodynamic driving force for diffusion, ...

Fick’s laws(first and second Fick’s laws). These two laws of diffusion were originally postulated by the medical doctor Adolf Eugen Fick (1829–1901) (from whom they take their name) by analogy with energy transfer in conduction and not by experiment (Fick1855; Bird et al.2002). ...
Moisture uptake, D, from Fick's second law of diffusion as postulated for composite materials is shown in Equation (1), and the theoretical change in mass, M, of composite materials from water immersion is given in Equation (2) [43–45]. Here, M1 and M2 are the moisture contents of ...
公式6.5是通过求解扩散系数为常数时一维菲克第二定律方程的偏微分方程得到的解答。具体可参考大卫.费豪文...
Various solutions (Crank's) of Fick's law of diffusion have been used to predict moisture loss (ML) in osmotic dehydration, by correlating experimental data. Selection of a particular solution should depend on the sample geometry and the fulfillment of a number of assumptions made to obtain ...
