Взаимодействие частиц с поверхностью задается потенциалом твердых сфер. Одночастичная функция распределения, задающая локальную плотность, находится решением интегрального уравнения Фредгольма второго рода. Ядро и правая часть уравнения Фредгольма вычисляется аналитически в приближении Перкус–Йевика. Получено аналитическое решение модифицированного синглетного уравнения с учетом нелокальных взаимодействий.</p></abstract><trans-abstract xml:lang="en"><p>A molecular system of hard spheres adjacent to a perfectly smooth solid surface is considered. The interaction of particles with the surface is determined by the potential of hard spheres. The single-particle distribution function, which sets the local density, is found by solving the Fredholm integral equation of the second kind. The core and the right-hand side of the Fredholm equation are calculated analytically in the Percus–Yevick approximation. An analytical solution of the modified singlet equation is obtained, taking into account nonlocal interactions.</p></trans-abstract><kwd-group xml:lang="ru"><kwd>локальная плотность жидкости</kwd><kwd>частичные функции распределения</kwd><kwd>синглетные уравнения</kwd><kwd>уравнение Фредгольма</kwd></kwd-group><kwd-group xml:lang="en"><kwd>local fluid density</kwd><kwd>partial distribution functions</kwd><kwd>singlet equations</kwd><kwd>Fredholm equation</kwd></kwd-group><funding-group><funding-statement xml:lang="ru">Авторы признательны участникам 14-го Всероссийского семинара “Физико-химия поверхностей и наноразмерных систем” в ИФХЭ РАН им.
