求翻译：当发射指令下达时，推进器下方点火，点火后，由于燃料迅速燃烧导致推进器所喷出强大的气流的反作用力，火箭整体开始逐渐离开地面。推进器推动火箭升空后会在两分钟以后分解成四个部分脱离火箭，其他部分继续上升。一分钟以后一级和二级火箭分离，一级火箭落下。又过了一分钟，整流罩分离。之后，天宫一号进入近地点约两百公里，远地点约346.9公里的运行轨道。三分钟后太阳能电池帆板打开。通过之前关于轨道数据的运算和多次对飞行轨道高度的调整，天宫一号飞行器将进入指定的轨道运行。这时火箭的发射就成功了。是什么意思？

When launching instructions issued, and propeller beneath the ignition, ignition, fuel burn rapidly lead to propeller emitted powerful air currents, the recoiling rocket overall gradually start off the ground. booster rocket launch promotion Later on, in two minutes later broken down into four parts

When launching instructions issued, and thruster below the ignition after ignition, because fuel combustion quickly lead to reaction thrusters emit a strong airflow, the rockets began to leave the ground as a whole. Propeller drive rocket after liftoff will be broken down into four parts in two minu
