In 1855, Adolf Fick proposed Fick's Law of Diffusion to explain the process of diffusion in a simple way. Fick's Law of Diffusion is a combination of two different laws which explains diffusivity and its applications.

其中，\( C \) 代表体积浓度（kg/m³），\( t \) 是扩散时间（s），\( x \) 是距离（m），而 \( D_0 \) 是视为常数的扩散系数。这两个方程本质上都是偏微分方程。为了求解它们，我们可以进行变量变换，比如令 \( u = \frac{\partial C}{\partial x} \)，将偏微分方程...
Fick’s First Law It is considered that the concentration gradient of elements in mineral and rock resulted from an evidence of diffusion, and the nonequilibrium state was frozen in them. The mobile element found the concentration gradient in material is useful as the tracer to estimate the time...
Fick's law [′fiks ‚lȯ] (physics) The law that the rate of diffusion of matter across a plane is proportional to the negative of the rate of change of the concentration of the diffusing substance in the direction perpendicular to the plane. ...
