Для NPKS-удобрения как объекта исследования использовали различные способы пробоподготовки, затем для каждой пробы по спектру РФА измеряли набор свойств, составляли матрицу «объекты - признаки», изучали корреляции «признак - признак» и выделяли наиболее информативные показатели для проведения классификационного анализа по крупности частиц в запрессованной пробе (интенсивности линий средних по атомной массе элементов, в особенности калия). Рассчитаны статистические показатели для каждого типа пробоподготовки исследуемого объекта.</p></abstract><trans-abstract xml:lang="en"><p>A key feature of the analytical control in industrial production is a constant striving for automation and shortening of the time of analysis. Optimization of the sample preparation which is the most time-consuming and inaccurate stage of any chemical analysis is first required to achieve the goals. The case study of NPKS-fertilizer using x-ray fluorescence analysis (XF) is presented to assess different methods of sample preparation. A matrix «object - characteristic feature» is compiled for NPKS fertilizers and most informative indicators are specified for ranging analysis of the particles in size in pressed sample. The line intensities of middle (by atomic mass) elements, potassium in particular, are considered the most informative features for this purpose. Statistical indices are calculated for each type of sample preparation.</p></trans-abstract><kwd-group xml:lang="ru"><kwd>рентгенофлуоресцентный анализ</kwd><kwd>сложные фосфорсодержащие минеральные удобрения</kwd><kwd>подготовка проб к анализу</kwd><kwd>анализ больших данных</kwd><kwd>многофакторный анализ</kwd><kwd>x-ray fluorescence analysis</kwd><kwd>complex phosphorus-containing fertilizers</kwd><kwd>sample preparation</kwd><kwd>analysis of large data array</kwd><kwd>multivariate analysis</kwd></kwd-group></article-meta></front><back><ref-list><title>References</title><ref id="cit1"><label>1</label><citation-alternatives><mixed-citation xml:lang="ru">Abouzeid A.
