摘　　要：Sublimation energy is the latent heat of phase transition from sohd state directly to gas state, but it is difficult to measure experimentally. We propose a new method to determine the sublimation energy of materials by using the experimental data of blow-off impulse induced by electron beam and the computer program DRAM. With th＆ new method, the sublimation energy of polyester is finally determined to be about 1.1 k Jig.Sublimation energy is the latent heat of phase transition from sohd state directly to gas state, but it is difficult to measure experimentally.
