大型火箭的发射是一幅壮观的图景:橘红色的火焰从箭体的喷管中喷出,在消焰槽中化成白色的气雾。火箭轰鸣,直冲天外,一组组雷达和光学观测仪追踪它的身影,将一串串数据信号显示在控制中心的大型显示屏上。 The launch of a large rocket is a spectacular picture: an orange flame spouts from the lance tube and turns into a white aerosol in a flame-holding tank. Rocket roar, rampancy, a group of radar and optical observer to track its shadow, a string of data signals displayed in the control center of the large screen.
