To assess the anisotropy degree of the sample from the shear wave velocity the generalized anisotropy factor
[B.sub.S] was calculated by the formula:
The ellipsoid is characterized with two parameters: the anisotropy factor
for the irregularities equaling to the ratio of ellipsoid axes [chi] = [l.sub.[parallel]]/[l.sub.[perpendicular to]] (ratio of longitudinal and transverse sizes of plasma irregularities with respect to the external magnetic field) and orientation characterizes by the inclination angle [[gamma].sub.0] of the prolate irregularities with respect to the lines of forces of an external magnetic field (sometimes with respect to horizon).
The absorption coefficient and anisotropy factor
of the second layers were chosen as minimum values given in  for 500-550 nm wavelengths, 0.6 ([cm.sup.-1]), and 0.87, respectively.
This function is characterized by anisotropy factor
of irregularities X = [l.sub.[parallel]]/[l.sub.[perpendicular to]](ratio of longitudinal and transverse linear scales of plasma irregularities with respect to the external magnetic field) and the inclination angle of prolate irregularities with respect to the external magnetic field [[gamma].sub.0].
a = [square root of [[lambda].sub.[parallel]]/[[lambda].sub.[perpendicular to]]]] = thermal conductivity anisotropy factor
The degree of orientation, or anisotropy factor
(AF), is defined as the difference between the principal values of (uu):
Beside paper--dye interaction (mainly, cross-section profile of raster element) our interest will also be focused on investigation of influence of anisotropy factor
in our model which could be important for optimization of paper components initial mixture.
The optical parameters absorption coefficient ([[micro].sub.a]), reduced scattering coefficient ([[micro].sub.s.sup.]) and anisotropy factor
(g) of tissues and phantoms were determined by Monte Carlo simulation technique.
Determination of Anisotropy Factor
. Firstly, brain tissue phantoms were made for comparative pictures of photon distribution.
8, the anisotropy factor
ranges from 0 for an isotropic distribution of orientation to 1 for the case of perfect domain alignment in the x-y plane.
The calculations of the [V.sub.P] range of changes within the depths of 5-25 km (5.82-6.60 km/s) with the average of 6.27-6.40 km/s allow the anisotropy factor
variations to be estimated from 4 % to 9 %, Table 5.
The anisotropy factor
, that means the ratio of in-plane conductivity and conductivity in the direction perpendicular to the pellet plane, was 328 (PANI/MMT pellet) and 6.7 (pure PANI pellet), respectively.
