      <abstract xml:lang="ru">
        <p>В статье проф. Е. С. Федорова: "Изображение структуры кристалла векториальными кругами" изложен графический способ нахождения плотностей сеток граней кристалла (точнее: квадратов плотностей соответствующих сеток). Каждому, имевшему дело с определением плотностей сеток граней по указанному способу, известно, что при этом приходится делать некоторые построения, не особенно сложные, но тем не менее отнимающие довольно много времени. Настоящая статья имеет целью показать, каким образом можно упростить задачу, сведя чертежную работу до минимума.</p>

      <abstract xml:lang="en">
        <p>In the article by Prof. E. S. Fedorov, "Representation of Crystal Structure by Vector Circles," a graphical method is presented for finding the reticular densities of crystal faces (more precisely: the squares of the reticular densities of the corresponding nets). Anyone who has dealt with determining the reticular densities of faces by this method knows that it involves making certain constructions—not particularly complicated, but nonetheless quite time-consuming. This article aims to show how the task can be simplified, reducing the drafting work to a minimum.</p>
