And the impulse coupling coefficient is not sensitive to nozzle length and the distance between ignition zone and inner surface of nozzle.

而冲量耦合系数对点火区与聚光系统内表面的距离及喷管长度等参数并不十分敏感。

Propellant property and nozzle closure opening pressure have an important effect on the ignition transient.

推进剂的燃烧特性及喷管堵盖打开压强对点火升压过程有较大影响。

Analysis shows that after three-time ignition and operation of motor, the temperature of nozzle case rises spirally.

分析认为，发动机三次启动点火工作，温度呈螺旋上升。
