摘　　要：通过理论计算探讨了DNTF的能量特性,由氮当量公式建立了DNTF的D-ρ0经验公式为D=2171+3651ρ0,计算的Dmax为9243m/s;DNTF的P-ρ0关系式为P=10.8175ρ02-0.574,计算的Pmax为40.01GPa;相对作功能力计算值为172.9%TNT当量。结晶形貌分析结果表明,纯DNTF的结晶形态、致密性及可熔铸性优于TNAZ,铸装药柱密度可达91%TMD以上,从而说明DNTF是一种具有高能量密度、高爆速、高作功能力的可铸装炸药。The energy character of DNTF was investigated by theoretical calculation, It is established that the experiential formation between detonation velocity(D) and density(ρ_0) is D=2　171+3651ρ_0. The calculated detonation velocity is 9 243　m/s. The relation between detonation pressure(P) and density(ρ_0) is P=(10.8175)ρ_0~2-0.574. The calculated result is P_(max)=40.01GPa. A high relative power is 172.9% TNT-equivalent. In comparison with the crystal structure of TNAZ, pure DNTF has better crystal structure, compactness and melt castibility, and the loading density is more than 91%TMD. The results indicate that DNTF is a new kind of castable energetic material with high energy density and low melting point.
