Law of fick
Web菲克定律的英文名称为Fick's Law，中文名称还有费克定律、斐克定律。 但是，现在中文教材基本上已经统一称之为“菲克定律”。 菲克定律分为菲克第一定律，和菲克第二定律： … WebFick's laws of diffusion describe diffusion and were derived by Adolf Fick in 1855. They can be used to solve for the diffusion coefficient, D. Fick's first law can be used to derive his second law which in turn is identical to the diffusion equation.
