The paper deals with the discriminant of the reduced system of n trinomial algebraic equa-
tions. We study zero loci of truncations of the discriminant on facets of its Newton polytope. The basis
of the study is the properties of the parametrization of the discriminant set of the system and the general
combinatorial construction of the tropicalization of algebraic varieties Рассматривается дискриминант приведенной системы n триномиальных алгебраических уравнений. Исследуются срезки дискриминанта на гиперграни его многогранника Ньютона.
Основой исследования являются свойства параметризации дискриминантного множества системы
и общая комбинаторная конструкция тропикализации алгебраических многообразий
