The four quadrant impulse correction scheme may lead to the losing of thrust and the increasing of miss distance, since this scheme cannot measure the exact target azimuth information.
四象限脉冲修正方案由于没有准确的目标方位信息，会造成脉冲推力损失和脱靶量增大；

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.
