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。

Under the same wall heat condition, with the increase of momentum correction coefficient, viscosity loss of the nozzle increases, but thrust and specific impulse decrease.

在同等壁面热条件下，随着动量调节系数的增加，喷管粘性损失增大，喷管的推力和比冲都将下降；
