The Darboux transformations are given also in an integral form. A correspondence between the diﬀerential Darboux transformations and the integral ones has been established. The second-order Darboux transformations are analyzed both at diﬀerent energies and at the same transformation energy. The method is illustrated by several examples of constructing quantum potential wells with a given spectrum.</abstract><trans-abstract xml:lang="ru">Преобразования Дарбу n-го порядка разрабатываются для обобщённого уравнения Шрёдингера, обладающего помимо обычного потенциала эффективной массой, зависящей от координаты, и дополнительным потенциалом, линейно зависящим от энергии. Приведён интегральный вид преобразований Дарбу и установлена их связь с преобразованиями в дифференциальной форме. Проанализированы преобразования второго порядка как при разных энергиях, так и при одной и той же энергии преобразования. Метод проиллюстрирован конкретными примерами конструирования квантовых потенциальных ям с заданным спектром.</trans-abstract><kwd-group xml:lang="en"><kwd>generalized Schr̈odinger equations</kwd><kwd>Darboux transformations</kwd></kwd-group><kwd-group xml:lang="ru"><kwd>обобщённые уравнения Шрёдингера</kwd><kwd>преобразования Дарбу</kwd></kwd-group></article-meta></front><body></body><back><ref-list><ref id="B1"><label>1.</label><mixed-citation>Ring P., Schuck P.
