本文系统地研究了在化学计量比的氩气模拟空气混合物中，烷烃甲烷通过戊烷的反射激波后的点火延迟时间。甲烷被发现是显着低于其他碳氢化合物的反应，表现出点火延迟时间约一个数量级长于他们。除乙烷外，点火延迟时间随分子中碳原子数的增加而减小，但不同燃料之间的差异不大。对观测到的乙烷着火延迟时间过低的现象进行了解释。
A systematic study has been made of ignition delay times behind a reflected shock wave of the alkanes methane through pentane in stoichiometric argon simulated air mixtures. Methane was found to be significantly less reactive than the other hydrocarbons, exhibiting ignition delay times approximately one order of magnitude longer than them. With the exception of ethane, the ignition delay times decreased with increasing number of carbons atoms in the molecule, though differences among the various fuels were not great. An explanation is advanced for the observed anomalously low ignition delay times of ethane.
