爆轰过程中游离碳的状态研究

目的 研究高密度负氧平衡炸药爆轰过程中游离碳的状态。方法 结合爆轰合成纳米金刚石数值结果以及对固相爆轰产物的实验研究，对爆轰过程中游离碳的状态进行讨论。用具有明确物理意义和纯石墨，金刚石，超微金刚石和类液碳的状态方程对多种炸药的爆速进行计算。结果与结论 用超微金刚石和类液碳的状态方程比用纯石墨和金刚石的状态方程预报的炸药爆轰参数更接近实验值，证明高密度负氧平衡炸药爆轰时ＣＪ点上游离碳主要是以液态或

Study of Free Carbon State in Detonation

Aim To study carbon state in detonation process of high density negative oxygen balance explosives.Methods\ Based on numerical modeling of detonation synthesis of ultrafine diamond (UFD) and experimental study of solid detonation products, the state of free carbon was discussed. By using the equations of states of pure graphite, diamond, ultrafine diamond and liquid like carbon, the detonation velocities of some explosives were calculated.Results and Conclusion Equations of states of ultrafine diamond and liquid like carbon can give better predictions to the detonation parameter of explosives than that of pure graphite and diamond. It demonstrates, for high density explosives, at CJ point in detonation, free carbon is more likely in the state of liquid carbon or liquid like carbon.
