The experiment results show that when the qualities of CL-20 increase, the critical explosion temperature has little change, the acetone has a certain restraint to the thermal decomposition of CL-20. When the concentrations of CL-20 solution increase and the heating rate is unchanged, the critical explosion temperatures of CL-20 solution increase firstly and then drop, the critical explosion temperature is the highest when the concentration of CL-20 is 6 ％. When the concentration of CL-20 solution is constant and the heating rates increase, the critical explosion temperature of CL-20 solution increases gradually. The results have significance on study
