翻译后摘要：一个球形爆轰波的传播提出了一种新的理论。该模型是在爆轰介质中的点球形爆炸。反应速率被假定为有限的，但冲击波运动和化学反应之间的耦合是由一个全球性的功能，导致有效的化学能量释放在爆轰前沿，这取决于当地的冲击波强度和冲击波半径建模。所获得的重要结果是证明存在的有限稳态速度低于理论平面查普曼-茹盖值。这些最终稳态速度的大小取决于用于引发爆震波本身的点火能量的值。
Abstract : A novel theory for the propagation of a spherical detonation wave is presented. The model is that of a point spherical blast in a detonating medium. The reaction rates are assumed to be finite but the coupling between the shock motion and the chemical reactions is modelled by a global function which leads to an effective chemical energy release at the detonation front which depends on the local shock strength and the shock radius. The important result obtained is the demonstration of the existence of finite steady-state velocities which are below the theoretical planar Chapman-Jouguet value. The magnitude of these final steady-state velocities depends on the value of the ignition energy used to initiate the detonation wave itself.
