ZND理论构成了我们对爆炸的大多数分析理解的基础，将它们描述为由波本身触发的化学反应持续的超音速燃烧波。然而，ZND理论的适用性取决于许多假设，如一维性、行波的稳定性和不存在耗散效应。先前的一些工作已经致力于获得一种简化的无粘爆炸渐近理论，该理论试图捕捉其非定常多维性质（例如[1,3,6,7]）。这些工作代表了超越ZND理论的一步，并允许对无粘爆炸的更深层次的理论理解。在ZND理论中合理地纳入耗散过程的研究较少。
The ZND theory comprises the basis for most of our analytical understanding of detonations, describing them as supersonic combustion waves sustained by chemical reactions that the wave itself triggers. The applicability of the ZND theory, however, depends on a number of assumptions, such as onedimensionality, steadiness of the traveling wave, and absence of dissipative effects. Several prior works have been devoted to obtaining a simplified asymptotic theory of inviscid detonations which attempt to capture their unsteady multidimensional nature (e.g. [1, 3, 6, 7]). These works represent a step beyond the ZND theory and allow for a deeper theoretical understanding of inviscid detonations. Much less attention has been paid at rationally incorporating dissipative processes in the ZND theory.
