本文数值求解了自由火焰在开放空间中传播引起的爆轰波形成问题。爆震形成的机制，减少到局部形成的冲击波的发展过程中的线性阶段的不稳定增长的扰动形成的表面上的一个扩大的火焰前锋的描述。还制定了由所述机制为向爆轰过渡创造条件的基本准则。
In this paper, we numerically solve the problem of detonation formation resulting from free flame propagation in an unconfined space. The mechanism of detonation formation that reduces to the local formation of shock waves during the development of the linear stage of unstable growth of disturbances formed on the surface of an expanding flame front is described. The basic criteria for creating conditions for the transition to detonation by the mechanism described are also formulated.
