Abstract : An analysis was made and a solution was found with the aid of an electronic computer for a system of equations for thermal explosions; it is given in partial derivatives for reactions of the zero and first order with heat transfer by conduction in the zone of the reaction and a Newton heat exchange at the boundary. The basic characteristics of thermal explosions are exactly determined. The obtained results are presented in the form of approximate expressions connecting the characteristics of the thermal explosion with all parameters of the problem for a wide range of changes. A criterion is given for the applicability of the averaged volume of the equation for calculating the period of induction, in case the heat transfer in the reacting volume takes place by conduction. A method is offered for averaging the system of equations of thermal explosions. (Author)
