Fick's law is important in transport theory and nonequilibrium statistical mechanics. The Heisenberg equation of motion for density is examined to see how it could be reduced to the diffusion equation, which is exactly equivalent to Fick's law. Conditions that are required have been noted and their implications explored.
菲克定律在输运理论和非平衡统计力学中很重要。研究了密度的海森堡运动方程,以了解它如何能简化为扩散方程,而扩散方程与菲克定律完全等效。已指出所需条件并探讨了其影响。
