本文利用本征值分析法研究了影响氢氧混合气体Z形爆炸极限的主要因素。特别是，它表明，H和HO2的壁破坏是必不可少的第一和第三限制的发生，而O，OH，和H2O2发挥次要的，定量的作用，这样的限制。通过准稳态分析，得到了爆炸极限的近似三次方程，由此导出了包括非单调性损失状态在内的各种爆炸极限的显式表达式，并进行了讨论。
In this study, the essential factors governing the Z-shaped explosion limits of hydrogen-oxygen mixtures are studied using eigenvalue analysis. In particular, it is demonstrated that the wall destruction of H and HO2 is essential for the occurrence of the first and third limits, while that of O, OH, and H2O2 play secondary, quantitative roles for such limits. By performing quasi-steady-state analysis, an approximate, cubic equation for the explosion limits is obtained, from which explicit expressions governing the various explosion limits including the state of the loss of non-monotonicity are derived and discussed.
