从理论上证明：对这两类发动机的两相喷管流动特性可以通过一个共同的组合参数——当量排气速度来进行分析；
Theoretically, it is proved that for both these engines, the properties of two-phase flow in nozzle can be analysed with a common combined parameter which is equivalent to exhaust velocity.
本文提出了一个新的两相流底排气体动力学模型。
在该模型中考虑了底排出口面积比，排气固相颗粒质量比，燃料热值，燃气分子量，燃烧室总温，飞行马赫数等因素。
In the model the exit area ratio, solid particle mass ratio, fuel enthalpy of combustion, jet gas molecular weight, chamber stagnation temperature, flight Math number etc. have been considered.
