Therefore, the relative permeability
resistances of specimens were mainly improved with the curing time larger than 3 hours and PSS concentrations higher than 3% (see Figure 10 and Table 7).
Capillary end effects accounted for the effects of rate on relative permeability
. Studies [38,43] indicated that observed rate dependency of wetting phase experiment results at high IFT was reproduced by simulations with constant relative permeability
(Kr) and capillary pressure (Pc), while observed rate effects of wetting phase in experiments were at low IFT systems and were interpreted as a result of rate dependency in the Kr function.
where [omega] is the angular velocity of the excitation alternating current; [[mu].sub.r] is the relative permeability
, which is 1000 for iron and 0.99991 for copper; [[mu].sub.0] is the permeability of the vacuum; [[epsilon].sub.0] is the permittivity of the vacuum; [[epsilon].sub.r] is the relative permittivity, which is 1 for both iron and copper; a is the conductivity of particles, whose value is 5.8 x [10.sup.7] S/m for copper and 1.0 x [10.sup.7] S/m for iron; and j is the imaginary unit.
If, for example, the strong coupling field, which drives the |b>-|a> transition and leads to two orthogonal dressed states |[+ or -]>, is switched off (i.e., the Rabi frequency [[OMEGA].sub.c] = 0 and hence the dressed-state mixing angle [??] = 0), the present atomic vapor will become a single negative- [[mu].sub.r] medium, of which the dispersion characteristics of both the real and the imaginary parts of the relative permeability
[[mu].sub.r] and the refractive index n are plotted in Fig.
where [k.sup.o.sub.rj] is the end point of relative permeability
meaning relative permeability
at residual saturation, [n.sub.j] is the exponent of relative permeability
of phase j determining the curvature of relative permeability
, [S.sub.nj] represents the normalized saturation of phase j calculated as follows:

Capillary pressure curves are used by the Brooks and Corey-Burdine model to calculate the relative permeability
of a fluid in porous media.

(3) We measured pressures of different sections after injecting asphalt micro-emulsion and got the resistance coefficient, residual resistance factor, and relative change of permeability of different part of the cores, thus evaluating the asphalt particles' capability to change mobility and to reduce the relative permeability
where k is the intrinsic permeability tensor, h the vertical depth, [k.sub.rj] the relative permeability
, [[mu].sub.j] the viscosity, and [[gamma].sub.j] the specific weight of phase j.
Furthermore, the oxygen relative permeability
of the precursor and uniaxially oriented nanocomposite fdms has been determined with different geometrical models.
For the sake of clarity and completeness, here we give the simulation and measurement results of the retrieved effective parameters of relative permittivity [[epsilon].sub.r], relative permeability
[[mu].sub.r], and refractive index n again, as shown in Fig.
