Abstract

Abstract: To reliably predict efficiency of solids, it is necessary to know the values of their thermofluctuation constants, which are determined by experimentally obtained data using graphical, graphoanalytical, and mathematical methods. Using the same initial data, the thermal fluctuation constants were determined by different methods. The graphical method is presented by calculation using graphs built on graph paper. The graphic-analytical method uses MS Excel. The mathematical method operates directly with equations instead of a graphical representation. It is shown that the chosen method of obtaining the constants has a significant effect on the final result. It is recommended to use a mathematical method when determining the thermal fluctuation constants.
