摘　　要：在JP-10点火延时的激波管实验中,JP-10在激波管壁的吸附导致气相浓度的不确定是测量结果分散的主要原因之一。利用精确测定的吸附曲线确定了实验时JP-10真实的气相浓度,解决了高碳数碳氢燃料点火延时激波管实验时管壁吸附影响燃料气相浓度确定的困难。实验显示JP-10的吸附符合Langmuir吸附等温关系。In shock tube measurements of the JP-10 ignition delay time, the uncertainty of the gas concentration due to the adsorption of JP-10in shock tube is one of the main reasons resulting in large scatter of measurement data. By measuring the adsorption curve accurately, the gas concentrations were determined, which overcomes the difficulty in determining the gas concentrations of heavier hydrocarbon fuels due to the adsorption on the wall in shock tube experiments. The present results of experiments show that the adsorption of JP-10 is in accord with Langmuir＇s adsorption isotherm.
