The collision momentum of condensed particles has little relation with the injection nozzle configuration under the same primary nozzleequivalent diameter.
在相同的一次喷嘴当量直径条件下，凝相颗粒的碰撞动量与喷嘴结构之间的关系不大。

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.
