本文基于湍流时流理论，对多孔氧格喷头几何轴线上的速度分布特征进行了理论和实验研究．结果表明，多孔氧论喷头轴线上速度最大值的临界枪位可由下式计算并由大型喷头的实测结果得到了验证
Based on the turbulent flow theory, theoretical and experimental studies on the velocity distribution on the geometrical axis of porous oxykine nozzles are carried out. The results show that the critical position of the maximum velocity of porous oxygen on the axis of the nozzle can be calculated by the following formula and verified by the measured results of a large nozzle
