Two-point method was established to determine the non-isothermal reaction kinetic parameters of energetic materials by using four parameters from two characteristic points on the non-isothermaI DSC curve. Two peak indexes H_w and τ_w were defined to judge the non-isothermaI DSC curve of energetic materials.It was found that only when these indexes coincided with the conditions of 0.1≤H_w≤1.0 and 1.8×1O^-2≤τ_m≤9.8× 1O^-2,the peak could be treated with kinetics methods. Some empiric judgements were given for chosen the most probable mechanism function and the reasonable kinetics parameters.A typical computation example was listed to compare the two-point method with those commonly used in kinetics.
