Applied Physics and Mathematics Annotation << Back Physicochemical measurements based on a direct measurement method V.A. Buzanovskii T.G. Samkharadze A.P. Vedernikova The processes of physicochemical measurements based on a direct measurement method are considered in the article. The systematization of these processes is carried out. The result of the systematization is a definition of five types of the processes. At the analysis of typical processes of physicochemical measurements based on a direct measurement method it is established that these processes can contain four stages – i) a stage of sampling, ii) a stage of sample transformation, iii) a stage of measurement and iiii) a stage of calculation of measurement result. The generalized mathematical description of direct transformation functions of the processes of physicochemical measurements based on a direct measurement method and direct transformation functions of their stages are offered. The results of the analysis of the developed mathematical description are submitted. In particular, the influence of direct and inverse transformation functions of stages on direct transformation functions of typical processes of physicochemical measurements based on a direct measurement method is determined. Key words: physicochemical measurement, direct measurement method, process, stage, systematization, sampling, sample transformation, direct transformation function, inverse transformation function.
