При этом вместо времени в нестационарное уравнение Шрёдингера входит координата дополнительной степени свободы – часов. Показано, что стандартное нестационарное уравнение Шрёдингера можно получить только для квазиклассических часов. Для выяснения физического смысла полученного таким образом уравнения обсуждаются различные виды часов. Кроме того, выводятся соответствующее уравнение для матрицы плотности и формулы для средних от операторов.</p></abstract><trans-abstract xml:lang="en"><p>A derivation of the time-dependent Schrödinger equation from the time-independent one is considered. Instead of time, the coordinate of an additional degree of freedom, the clock, is introduced into the original time-independent Schrödinger equation. It is shown that the standard time-dependent Schrödinger equation can be obtained for the semiclassical clock only. For elucidation of the physical meaning of the equation obtained in this way, various types of clocks are discussed. In addition, the corresponding equation for the density matrix and formulas for the mean values of operators are derived.</p></trans-abstract><kwd-group xml:lang="ru"><kwd>уравнение Шрёдингера</kwd><kwd>часы</kwd><kwd>квазиклассическое приближение</kwd></kwd-group><kwd-group xml:lang="en"><kwd>Schrödinger equation</kwd><kwd>clock</kwd><kwd>semiclassical approximation</kwd></kwd-group></article-meta></front><back><ref-list><title>References</title><ref id="cit1"><label>1</label><citation-alternatives><mixed-citation xml:lang="ru">Schrödinger E.
