Section: Physics. Mathematics. Informatics UDC538.911AuthorsAstapova Elena Stepanovna, Amur State University (Blagoveshchensk, Russia)Borilko Anton Sergeevich, Postgraduate Student, Amur State University (Blagoveshchensk, Russia) Astapov Ivan Aleksandrovich, Institute for Material Studies, Far Eastern Branch of the Russian Academy of Sciences (Khabarovsk, Russia) AbstractThe paper is devoted to the choice of approximation function to calculate the coherent-scattering region, exemplified by the hard alloy with 8 % Co–92 % WC. The constants of approximation functions Cauchy 1, Cauchy 2, Laue and Gaussian function were fitted by means of numerical methods. Function availability estimation was gained with the mean-square residual.KeywordsGaussian function, Cauchy function, Laue function, approximation, mean-square residual, block, thin crystal structure.The full-text version of the article can be requested through the university’s library.
