Abstract: A threetemperature thermonuclear burn model considering the slowingdown effect of alpha particles is presented, with which the temporal evolution of temperature and particle number density are calculated. Comparison with the description that alpha particles deposit their energy instantaneously, calculation shows that the slowingdown effect of alpha particles delays ignition time, makes the maximum of electron and ion temperatures lower and is more remarkable for lower density conditions.
