A new model of liquid water is proposed, which involves the liquid-crystall
ine phase, namely, the presence of linearly ordered chains of water molecul
es and large clusters of these molecules. The presence of linearly ordered
chains and clusters in liquid water makes itself evident after the exposure
of water to low-frequency electromagnetic radiation. The kinetics of the l
inearly ordered chains is described by nonlinear excitations (solitons). A
hydrodynamic equation describing the behavior of this model system was deri
ved. On the basis of the model, the dimensions of clusters were determined
( similar to 600 Angstrom). The calculated values of dielectric permeabilit
y in the range of low frequencies appeared to be close to their experimenta
lly obtained values. A tenfold increase in the stationary value of dielectr
ic permeability compared with the known value of the dielectric constant in
the frequency range of 10(4) - 10(6) Hz was predicted. The frequency depen
dence of dielectric permeability in this range was studied.
