Key words and phrases: conductometric cell; impedance; inductance; me-dium-ion resonant frequency; potassium chloride; capacitance.
Abstract: The effect of conductometric cell design on the results of measuring reactive components of impedance and medium-ion resonant frequency of oscillations of hydrated ions is studied. It is shown, that linearity of dependence C –1 on f 2 takes place only in the cell of the first type.

Measurement results in the cell of this type enable to calculate reactive components of impedance and medium-ion resonant frequency. Relative error of measurements doesn’t exceed 5 %.

Key words and phrases: complex plane; complex pseudo-Euclidean multiplication of vectors; main basis vectors; main directions on the complex pseudo-Euclidean plane; the space of Minkowski.
Abstract: Pseudo-Euclidean metrical properties may be superimposed on the complex plane by determining the commutative operation of complex pseudo-Euclidean multiplication of vectors. This operation does not ensure real positive value of the complex pseudo-Euclidean square of vector, but the first component of complex pseudo-Euclidean product of any vectors is identified with the scalar pseudo-Euclidean product of these vectors, that allows to apply the ordinary formulae as axiomatic definitions for length and angle. Thus we reveal that pseudo-Euclidean metrical properties of the plane are bound with the complex linear relations between its vectors.
