活细胞内微粒扩散运动研究

Diffusion theory of particles in live cells

利用统计物理方法，研究活细胞内微粒无规则运动引起的扩散过程，得出了扩散系数的表示式．结果表明。

The diffusion process rising from the random motion of the particles in live cells is studied by using the method of the satatistical physics, and the formulas of the diffusion coefficient are obtained. The results show that the diffusion coefficient of the live particles is equal to the sum of the diffusion coefficients of the Brownian movement and the saltatory movement which is peculiar to the live particles. Some quantitative calculations and discussions are carried out with the data reported in some literatures .
