摘　　要：本文扼要地介绍了航空航天部三十一所1988年11月利用电弧加热器所进行的M=2的超音速气流中横向喷射氢燃料和煤油的点火情况,描述了点火现象的物理特性,并提出了点火准则中的修正系数.Ignition test of hydrogen and kerosene fuels injected transversely into Mach 2 supersonic airstream heated in a electric arc wind-tennel, carried out by 31st Research Institute, MAS(Nov.1988)is introduced in brief .Physical characteristics of ignition are described and a modified coefficient for ignition criterion is also proposed in this paper.
