Nanopowders based on zirconia due to their high dispersion are prone to adsorption of water from the surrounding atmosphere and formation a layer of adsorbed water on the surface of nanoparticles. Therefore, taking into account the processes of formation of adsorbed layers of water on the surface of nanoparticles in real atmospheric conditions, their structure and characteristics, as well as their impact on the structure and electrophysical properties of zirconia nanoparticles are very interesting. The influence of the degree of hydration on the electrophysical properties of compacted hydrated nanoparticles of zirconia was investigated and a quantitative layer-by-layer model of the hydrated particle was constructed, the number and order of adsorbed water layers on the surface of nanoparticles at different ambient humidity were determined. The presence of three relaxation processes in the system nanoparticle – adsorbed water layer was established, which indicates different mobility of water molecules in the adsorbed layer and corresponds to its three components - Stern layer, diffuse layer and free water layer in the space between particles. Increasing the degree of hydration of the compacted powder from zero to the most water-saturated leads to sequential filling of the adsorbed layer on nanoparticles, which leads to an increase in electrical capacity of the respective components of the adsorbed layer for the Stern layer in 13 times and for the free water layer in 15 times. Based on the known model of the structure of the electric double layer and obtained data, the parameters of the electric double layer of nanoparticles was calculated.

The military charter is defined in the article as a major type of administration document in the Don Host Province (Rus. Oblast’ Voyska Donskogo) and is claimed to be an exceptional genre of administrative documentation of the 18th century. The study is conducted with reference to documents (dated between 1735 and 1755) from the Mikhailovsky Stanitsa Ataman Archive (State Archive of Volgograd Region). Applying a complex approach to linguistic phenomena analysis and taking into account the achievements of the modern text theory through the prism of documentation linguistics, the authors determine the following characteristics of any genre of a documentary text: functions, subjects of communication (addresser, addressee), specificity of the message delivered, composition structure, prevailing modality, time and space localization. The authors illustrate their multi-vector and heterogeneous interaction and coordination with the specific features and general text categories and properties of the text. The notion of genre that was first introduced in linguistics with reference to fiction is specified for documentation linguistics; conceptual information in official and administrative documents is considered as a cultural and historical background that helps to provide an accurate interpretation of factual information. The authors characterise the peculiarities of the aforementioned parameters in the speech structure of military charters that are expressed by different level means of language, emphasising the cases that allow for variability. The article demonstrates that though it is an isolated textual phenomenon, the military charter reflects the peculiarities of records management typical of a certain area of Russia. Keeping some old instructive traditions, the text, however, demonstrates some features of the new office style of the 18th century., В статье обосновано определение войсковой грамоты — главного управленческого документа Области Войска Донского — как уникального жанра деловой письменности XVIII в. Исследование проведено на материале документов 1735–1755 гг. фонда «Михайловский станичный атаман», хранящегося в Государственном архиве Волгоградской области. Применение комплексного подхода к анализу языковых явлений и учет достижений современной теории текста, осмысленных с позиций документной лингвистики, позволили установить следующие параметры жанра любого документного текста: функция, субъекты коммуникации (адресант и адресат), характер передаваемой информации, структура, доминирующая модальность, пространственно-временная локализация. Показано их многовекторное, разноплановое взаимодействие и соотнесенность с общими текстовыми категориями и свойствами документа. Уточнены представления о жанре, разработанные в лингвистике на материале художественного текста, в частности, концептуальная информация применительно к официально-деловым текстам понимается авторами статьи как культурно-исторический фон, обусловливающий достоверную интерпретацию фактуальной информации. Охарактеризованы особенности экспликации названных параметров в речевой структуре войсковых грамот разноуровневыми средствами языка, особо отмечены случаи, допускающие вариативность выражения. Выявлено, что войсковая грамота, будучи самостоятельным жанром, отражает специфику делопроизводства на определенной территории России, но при этом вписывается в новую для XVIII в. канцелярскую систему, сохраняя в своем речевом воплощении приказные традиции.
