An analysis of spatially localized and time-periodic vibrational modes (discrete breathers – DBs) is carried out. It is found out that the discreteness and nonlinearity of the medium are the main necessary conditions for the existence of discrete breathers, and these conditions are satisfied in the crystal lattice. The role of DBs in the formation of the physical properties of crystals is discussed. The arguments are presented in favor of the fact that this role increases many times in the states far from thermodynamic equilibrium and in the lowstability pre-transitional states of the crystal lattice.

金属系统低稳定性状态下的空间局部振荡

对空间局部和时间周期振动模式（离散呼吸器 - DBs）进行了分析。发现介质的离散性和非线性是离散呼吸器存在的主要必要条件，而这些条件在晶格中都得到满足。讨论了 DBs 在晶体物理性质形成中的作用。提出的论点支持这样一个事实，即在远离热力学平衡的状态和晶格的低稳定性过渡前状态中，这种作用会增加很多倍。
