During XX-5A experiments, the active modification of the ionosphere resulted by rocketexhaust was monitored with GPS receiver.
在XX - 5 A试验期间，GPS接收机监测到了火箭排出的“废气”所造成的电离层有源变态效应。

The rocketexhaust plume causes the effects of noise, smoke, flame and heat radiation, environment pollution and signal attenuation, etc. So it is important to study exhaust plume.
火箭羽流会造成噪声、烟雾、热辐射、环境污染和信号衰减等多种效应，因此研究排气羽流问题至关重要。

This makes a powerful exhaust through the back of the rocket and pushes the rocket up.
