   <abstract xml:lang="ru">
    <p>Описана методика приготовления сильно разбавленных растворов путем итерационного разбавления, сопровождающегося интенсивным механическим воздействием. Представлены результаты измерений высокочастотной электропроводности и диэлектрической проницаемости серии образцов L и D изомеров аланина и валина. Отсутствие диэлектрического инкремента во всех образцах свидетельствует об отсутствии в растворах мезочастиц с высокой диэлектрической проницаемостью. Зарегистрирована немонотонная, сложная зависимость электропроводности от числа N итераций разбавления. Такого типа зависимость сохраняется при больших N, когда понятие концентрации растворяемого вещества теряет смысл, что свидетельствует об изменениях состава водных растворов при механических воздействиях. Повторные измерения образцов, хранившихся в закрытых флаконах, находившихся в закрытых картонных коробках при комнатных условиях, выявили долговременные эволюционные процессы в водных растворах. Особенность эволюции электропроводности растворов аланина и валина, по сравнению с ранее исследованными потенцированными растворами диклофенака, состоит в уменьшении электропроводности со временем, что противоречит дополнительному растворению углекислого газа из атмосферы при открытии флаконов и растворению стекла. Различий в свойствах растворов L и D изомеров аланина и валина не обнаружено.</p>

    <p>The method of preparation of highly diluted solutions, by iterative dilution accompanied by intense mechanical action is described. The results of high-frequency electrical conductivity and dielectric permittivity of L and D isomers of alanine and valine are presented. The absence of dielectric increment in all samples indicates the absence of mesoparticles with high dielectric permittivity in solutions. A non-monotonic, complex dependence of electrical conductivity on the number of N dilution iterations is recorded. This type of dependence persists at large N, when the concept of the solute concentration loses its meaning, which indicates changes in the composition of aqueous solutions under mechanical impact. Repeated measurements of samples stored in closed vials in closed cardboard boxes at room conditions revealed long-term evolutionary processes in aqueous solutions. The peculiarity of the evolution of the electrical conductivity of alanine and valine solutions, in comparison with the previously studied potentiated diclofenac solutions, consists in a decrease in electrical conductivity over time, which contradicts the additional dissolution of carbon dioxide from the atmosphere when opening vials and dissolving glass. There were no differences in the properties of L and D isomers of alanine and valine solutions.</p>
