I Cheredov V. N. Entropy model of crystals of hexagonal ice
A refined entropy model of hexagonal ice crystals is developed, including an interpretation of the entropy of hindered translations and hindered vibrations on the basis of the Einstein model. The temperature dependence of the entropy in the refined entropy model of hexagonal ice crystals is studied. A comparison of the proposed model with the complete and modified entropy models of ice is made.
Comparative features of the temperature curves of thermodynamic and spectroscopic entropy for the refined entropy model of ice crystals, modified and known, were studied. It is shown that the proposed refined entropy model describes the temperature dependence of the entropy of hexagonal ice crystals with greater accuracy in comparison with known models.
Keywords: Thermal vibrations, entropy, lattice of a solid, crystals, hexagonal ice.

II Petrakov А. Р., Cheredov V. N. Refined modified thermodynamic model of crystals of hexagonal ice
The heat capacity of crystals of hexagonal ice and its dependence on temperature in a modified modified thermodynamic ice are studied. A refined modified thermodynamic model of ice is developed, based on the interpretation of the heat capacity of hindered translations and inhibited rotations on the basis of the Einstein model. A comparison of the proposed model with known thermodynamic ice models is made.
The comparative features of the temperature curves of the heat capacity for the proposed model, as well as the complete and modified by the thermodynamic models of ice crystals are studied. It is shown that the proposed refined modified thermodynamic model describes the temperature curve of the heat capacity of hexagonal ice crystals with greater accuracy in comparison with known models.
Keywords: thermal oscillations, heat capacity, lattice of crystal, hexagonal ice.

VII Dorofeev S. N. UDE as a basis for improving the quality of mathematical knowledge of students when studying the topic «parallelism of straight lines on a plane»
This article examines the problem of improving the quality of mathematical education of primary school students. It is proposed to use the method of consolidation of didactic units developed by the famous Russian scientist P. M. Erdniev as the leading component that determines the increase in the level of mathematical training of schoolchildren and contributes to its quality. The effectiveness of this method is justified and an ESSAY on the topic «Parallelism of straight lines on the plane» is proposed, which contributes to a more effective assimilation of this topic.
Keywords: quality of geometric education of students, consolidation of didactic units, basics of teaching methods, motivation to learn.
