In the event (due to the action of the potential difference at the ends of the capillary), one charge is a tendency to move in one direction, the other in the opposite. The charge of the solid phase is fixed motionless, and the charged layer in the stabilizing liquid moves along the surface of the capillary at such a speed that the friction forces R are balanced by electric forces. From this formula of the electrosmos it is clear that with a constant electric current I, the volume of passing stabilizing fluid during this time is directly proportional to the potential I on the surface of the section and dielectric permeability of the stabilizing fluid and inversely proportional to the viscosity and specific electrical conductivity of the X stabilizing fluid, and also does not depend on the area cross -section or capillary length. Cellulose molecules are polar and belong to the category of dipole. Lignin molecules are polarized to a lesser extent. The polarity of pentosanov and their units with acety groups is similar to the polarity of cellulose molecules. Wood fabric can be represented by such a structural accumulation of magnets, the role of which is played by dipole elements of the structure. The orientation of each macromolecule or links of molecules is due to electric fields of neighboring macromolecules or their links forming an internal electrostatic field. Therefore, from a number of electrical parameters, the most valuable characteristic of solid and liquid bodies can be dielectric permeability. Its value depends not only on the conditions and methodology of measurement, but also on the structure, composition, state and behavior of bodies when measuring. In addition, this can hardly affect the value of dielectric permeability as a measure of some forces inherent in bodies, especially if measurements are carried out under the same conditions for various bodies.
