[求助] 颗粒扩散系数

Cunningham correction factor should not be included in a diffusion coefficient, since the statistics of the random walk process is not affected by the distance between the gas molecules relative to the size of the particle. However, this distance may affect the particle mobility in an external field.
但是很多文献中给出的颗粒扩散系数表达式中包含了Cunningham correction factor 。希望大牛们给些建议。
特别是这句话: since the statistics of the random walk process is not affected by the distance between the gas molecules relative to the size of the particle. However, this distance may affect the particle mobility in an external field. 这句话怎么理解?这句话与扩散系数是否应该包含Cunningham correction factor有关系吗?
