Abstract

Since the 1960s at the Keldysh Institute of Applied Mathematics team led by N.N. Kalitkin creates the TEFIS database on the thermophysical properties of substances. In recent years, this database has included a section on the rates of chemical reactions that describe several relevant processes. For this, new mathematical methods for regression of experimental data measured with significant errors were developed. This paper presents the current state of work in this area.
