Кроме механических и прочностных характеристик льда как твердого тела, имеют большое значение характеристики поверхностей льда, проявляемые в процессе трения. В работе исследовалось трение двух монокристаллов льда друг относительно друга как основа для понимания закономерностей трения натурного, поликристаллического льда. В работе приведены результаты измерения характеристик сухого трения покоя и трения скольжения монокристаллов льда. Из искусственно выращенной пластины монокристалла льда для эксперимента изготавливались образцы монокристаллов льда с определенной ориентацией С-оси. Измерение коэффициента трения покоя монокристалла льда реализовалось по классической схеме регистрации минимального угла, при котором монокристалл начинал скатываться по наклонной поверхности второго монокристалла. Была обнаружена зависимость коэффициента трения покоя монокристаллов льда от взаимной ориентации С-осей монокристаллов друг относительно друга. Коэффициенты трения покоя в случае, когда С-оси монокристаллов льда параллельны друг другу, значительно превысили коэффициенты трения покоя в случае, когда С-оси монокристаллов льда перпендикулярны друг другу.Проведенные исследования показали наличие анизотропии сил трения пары монокристаллов льда.</p></abstract><trans-abstract xml:lang="en"><p>The properties of the ice of natural reservoirs are due to its crystalline structure. The dependence of the mechanical and strength characteristics of single ice crystals on the angle between the direction of application of force to a single crystal and the direction of its C-axis is known. Basically, this dependence is due to the possibility of the base plates of a single crystal of ice sliding relative to each other. In physics, in addition to the mechanical and strength characteristics of a solid, the properties of the surfaces of a solid state, manifested in the process of friction, are of great importance. The friction of two single crystals of ice relative to each other has been investigated in experiments on rest friction and sliding friction. From an artificially grown plate of a single ice crystal, samples of single crystals of ice with a certain orientation of the C-axis were made for the experiment. The measurement of the rest friction coefficient of a single ice crystal was realized according to the classical scheme of recording the minimum angle at which the single crystal began to roll down an inclined surface. The dependence of the rest friction coefficient of ice single crystals on the mutual orientation of the C-axes of single crystals relative to each other was discovered. The coefficients of rest friction in the case that the C-axes of single ice crystals are parallel to each other significantly exceed those obtained when the C-axes of single ice crystals are perpendicular to each other. Measurements have shown that the anisotropy of sliding friction increases with increasing initial velocity of the single crystal on the surface of the second single crystal. This is explained by the fact that with the growth of the path traveled by the M2 crystal, the time of interaction of single crystals of ice also increases, during which the properties of the anisotropy of single crystals of ice relative to sliding friction are manifested. Studies have shown the presence of anisotropy of the friction forces of rest and friction of sliding of a pair of single crystals of ice.</p></trans-abstract><kwd-group xml:lang="ru"><kwd>анизотропия</kwd><kwd>базисные плоскости</kwd><kwd>монокристалл льда</kwd><kwd>С-ось монокристалла</kwd><kwd>трение покоя</kwd><kwd>трение скольжения</kwd></kwd-group><kwd-group xml:lang="en"><kwd>anisotropy</kwd><kwd>base planes</kwd><kwd>C-axis of single crystal</kwd><kwd>rest friction</kwd><kwd>single ice crystal</kwd><kwd>sliding friction</kwd></kwd-group><funding-group><funding-statement xml:lang="ru">Работа выполнена по теме «Исследование крупномасштабной динамики, физических процессов, механики деформирования и разрушения морских льдов» ЦНТП 052626 раздел 5.1.5</funding-statement><funding-statement xml:lang="en">The work was carried out on the topic “Study of large-scale dynamics, physical processes, mechanics of deformation and destruction of sea ice” CSTC 052626 section 5.1.5.</funding-statement></funding-group></article-meta></front><back><ref-list><title>References</title><ref id="cit1"><label>1</label><citation-alternatives><mixed-citation xml:lang="ru">Яворский Б.М., ДетлафА.А.
