Аннотация:Wepresent a computer simulation study of the influence of the confinement on the density anomalyin the fluid with isotropic core-softened potential which is used for a qualitative description of theanomalous behavior of water and some other liquids. We have found that a maximum temperature of the density anomaly region along an isochor ρ = 0.5 does not depend on the pore width. We have shown that a decrease in the width of the confining slit pore leads to an increase in the crystallizationtemperature while the temperature of the density anomaly remains constant. Because of this, thetemperature range of the density anomaly becomes less and will disappear under the crystallizationline in the pores of a very small width.
