Abstract: Importance of accurate calculation of average reaction rate in thermonuclear reactions is introduced. Two types of nuclear involved in thermonuclear reactions are assumed in thermal equilibrium state under same temperature. With comparison between analytical expressions of average reaction rate and average rate of thermonuclear reaction using MC method directly, correctness of MC method is obtained. Finally, MC method is extended to calculation of average thermonuclear reaction rate in several typical distributions.

Key words: thermonuclear reaction, Fokker-Planck equation, average thermonuclear reaction rate, Maxwell's distribution function
