【 摘 要 】

Experimental X-ray or electron-diffraction research of liquid allows to reliably assess the size of a lattice seat and holes in quasi-crystalline structures. According to the results of such research, lattice constants for a series of certain n-paraffins were calculated. The author used a hole model of liquids to obtain expressions which were later used to calculate enthalpies of activation of viscous current of n-alkanes and their mixtures. It allowed to connect the experimental work on definition of temperature dependency of liquids viscosity to the calculation of structure properties of liquid mixtures of non-electrolytes. Partly, such calculation was done while solving a problem of the composition of a surface layer of n-alkanes mixtures.
