Mass diffusion中文
Diffusivity, mass diffusivity or diffusion coefficient is usually written as the proportionality constant between the molar flux due to molecular diffusion and the negative value of the gradient in the concentration of the species. More accurately, the diffusion coefficient times the local concentration is the … See more Solids The diffusion coefficient in solids at different temperatures is generally found to be well predicted by the Arrhenius equation: where See more The effective diffusion coefficient describes diffusion through the pore space of porous media. It is macroscopic in nature, because it is not individual pores but the entire pore space that needs to be considered. The effective diffusion coefficient for transport through the pores, … See more For self-diffusion in gases at two different pressures (but the same temperature), the following empirical equation has been suggested: See more In population dynamics, kinesis is the change of the diffusion coefficient in response to the change of conditions.

Diffusion is the net movement of anything (for example, atoms, ions, molecules, energy) generally from a region of higher concentration to a region of lower concentration. Diffusion is driven by a gradient in Gibbs free energy or chemical potential. In the context of Quantum Physics, diffusion refers to spreading of wave packets.
