      <abstract xml:lang="ru">
        <p>Привлечение математических методов находит все большее применение в гидрогеохимии. Наибольшее распространение получила математическая статис­тика, с помощью которой решаются разнообразные задачи, в частности опре­деление силы и характера связи между признаками, а также степени влияния отдельных факторов формирования химического состава вод.</p>

        <p>Involvement of mathematical methods is increasingly used in hydrogeochemistry. The most widespread is mathematical statistics, which is used to solve a variety of problems, in particular, to determine the strength and nature of the relationship between the features, as well as the degree of influence of individual factors in the formation of the chemical composition of waters.</p>
