| description | The origin of kinematic shear viscosity in liquid alkaline metals has been studied. It is shown that, since the depth of the well in the potential of pair interaction between ions is small in comparison with the energy of thermal motion of those ions, the mechanism of kinematic shear viscosity formation is not an activation one. The main mechanism consists in the momentum transfer from one layer to another and depends on the layer “roughness”. In accordance with the generalized similarity principle, liquid alkaline metals are shown to belong to the same similarity class, and a similar character of changes in the isobars of the kinematic shear viscosity of liquid alkaline metals is observed only if this principle is applicable. A formula for the kinematic shear viscosity is proposed. The agreement of the results obtained with experimental data is quite satisfactory. |

У роботi дослiджено природу кiнематичної зсувної в’язкостi рiдких лужних металiв. В роботi показано, що внаслiдок малої глибини ями парної мiжiонної взаємодiї, порiвняно з енергiєю теплового руху iонiв, механiзм формування кiнематичної зсувної в’язкостi не є активацiйним. Основним механiзмом є перенос iмпульсу вiд одного шару до другого, що залежить вiд “шорсткостi” молекулярних шарiв. Згiдно з узагальненим принципом подiбностi показано,що рiдкi лужнi метали належать до одного класу подiбностi i подiбний характер змiни кiнематичної зсувної в’язкостi рiзних лужних металiв на їх iзобарах спостерiгається тiльки в рамках застосування цього принципу. Запропоновано формулу розрахунку кiнематичної зсувної в’язкостi. Узгодження з експериментальними даними є цiлком задовiльним.
