FIELD: physical methods for inspection of the state of water and its solutions in various objects, applicable in solution of fundamental and applied problems of water systems.
SUBSTANCE: the method is proposed for determination of the dielectric parameters of water and its solutions with conductivity 
= 20m S/cm within frequency band 10 kHz to 100 MHz with the aid of a set of inductance solenoids of an identical size (L-cells) connected to the oscillatory circuit of a Q-meter. Due to the fact that the object under inspection is introduced in the L-sells in a dielectric vessel so that the gap between the object and the winding of the measuring cell makes up 4 to 6 mm, the inductive principle of operation of the L-cells is realized owing to the rise of displacement currents of the object under inspection depending on the dielectric parameters of the object. The object dielectric parameters are in a weak rotational electric field of the L-cell, the value of tangent of dielectric field of the L-cell, the value of tangent of dielectric loss angle 
of the water object at the given frequency is calculated according to a definite relation for 
, and the dielectric permittivity is characterized by value 
and calculated according to a definite relation for 
. The found values of 
and 
depend on the quality factor and inductance of the measuring L-cell, if length l and radius r of its winding satisfy condition 
, 
20 mm, and the maximum strength of the rotational electric field inside it equals 
= 5 to 300 
. The method for measurement of the dielectric parameters of water objects is a method of non-destructive inspection procedure of their state, since the strength of electric field 
inside the L-cell is less than the strength of the field inside the measuring capacitors in the well-known capacitance method of measurement of the same parameters by several orders. As a result, in essence new information on the properties of water systems are revealed, for example, in the frequency band 10 kHz to 100 Mhz, and a low-frequency dispersion of dielectric permeability and low-frequency maximum 
connected with it is fixed.
EFFECT: finding, in addition to 
, of liquid dielectric permeability 
is provided, the values of 
and 
do not depend on the parameters of the measuring cell.
