中文摘要：

在JP-10和煤油点火特性激波管实验基础上，进行了促进剂CH3NO2、CH2Cl2对JP-10和煤油点火特性影响的实验。在预加热激波管上采用缝合运行技术，获得了近7his的实验时间。采用单色仪和光电倍增管记录点火过程中OH自由基在306．5nm发射谱强度变化作为点火发生的判据。当促进剂加入量约为JP-10的10％～20％（摩尔比），质量比为5％。12％时，实验观测到明显的点火促进作用。在1100K时，添加10％（摩尔比）CH3N02使JP-10的点火延时时间缩短了70％。当CH3NO2的加入量占煤油的10％～15％（摩尔比），质量比约为5％～6％时，对煤油点火有明显的促进作用，在1000K时使煤油点火延时时间缩短了50％。

英文摘要：

On the basis of the ignition experiments of JP-10 and kerosene in shock tube, the experiments of effect of enhancers, nitromethane and diehlormethane, on ignition characteristics of JP-10 and kerosene were performed. Under conditions for a tailored interface in a preheated shock tube, the experimental time of about 7 ms was obtained. The whole variation of the OH radical emission at 306.5nm was observed in the ignition process by a monochrornator with a photomultiplier, to identify the time to ignition. When the molar ratio of the added enhancer with the fuel accounted for 10% - 20%, correspondingly the mass ratio was 5% - 12%, a significant reduction in ignition time was observed experimentally. Specifically, at 1100K the addition of 10% mole ratio of CH3N02 produced a 70% reduction in the ignition time for JP-10. The ignition time of kerosene were shortened effectively, when 10% - 15 % mole ratio of CH3N02 was added, correspondingly the mass ratio was 5% - 6%. Specifically, at 1000K the ignition time for kerosene decreased by 50%.
