| 摘 要： | 用Gibbs自由能最小原理,通过解化学平衡方程组,求解HNO型炸药H32·685N16·8430O3·0(70/30Hydrazine/HydrazineNitrate)和H8·154N4·5770O3·0(21/79Hydrazine/HydrazineNitrate)爆轰产物系统的平衡组分,计算结果与用BKW和LJD方法计算的结果相近。以Ree修正的WCA状态方程并考虑Ross软球修正的硬球微扰理论作为爆轰气相产物的物态方程,用自编的程序对H32·685N16·8430O3·0和H8·154N4·5770O3·0炸药爆轰参数作了预言,爆轰CJ点的爆速、爆压和爆温的计算结果与实验值吻合得很好。 |

| Abstract: | The equilibrium compositions of H_ 32.685 N_ 16.8430 O_ 3.0 and H_ 8.154 N_ 4.5770 O_ 3.0 explosives detonation products are calculated by minimizing the Gibbs free energy, and by s olving the chemical equilibrium equations, and the results are in good agreement with t he results of BKW and LJD equation of state. The improved WCA equation and Ross's variatio nal perturbation theory are used for the equation of state of detonation products, a nd the detonation properties of H_ 32.685 N_ 16.8430 O_ 3.0 and H_ 8.15 4 N_ 4.5770 O_ 3.0 explosives have been calculated. The calculated detonation velocity, pressure and temperature at CJ point are in good agreement with experimental data. |
