permeability constant

A number that indicates the ratio between the concentration gradient across a membrane and the resulting flow of solution through the membrane. Permeability constant varies with the characteristics of the membrane and those of the solute.

In this case, the electric and magnetic constants, [[epsilon].sub.0] and [[mu].sub.0], are as follows:

Thus, the electric constant [[epsilon].sub.0] makes sense the linear density of the vortex tube current, and the magnetic constant [[micro].sub.0] makes sense the reciprocal value of the interaction force between two elementary charges.

A possible reason for this is the analogy proposed in the textbook [1] between the polarization of the dielectric [mathematical expression not reproducible] ([[mu].sub.0] is the magnetic constant), but the latter requires a theoretical justification.
