interporosity flow

[gritz]

Пожалуйста, помогите перевести.

Выражение встречается в следующем контексте:

The double-porosity model is described by two other variables in addition to the parameters defining the homogeneous model:  is the storativity ratio, and is essentially the fraction of fluids stored in the fissure system (e.g. =0.05 means 5%).
 is the interporosity flow coefficient that characterizes the ability of the matrix blocks to flow into the fissure system. It is dominated by the matrix/fissures permeability contrast, km/kf.
