I was searching through binoculars for the rocket and noticed it at this point, observing both the smoke cloud and the rocket descending by parachute, but then lost sight of it.
我是透过双筒望远镜搜索，为火箭，并注意到它在这一点上，观察双方的烟雾云和火箭降，由降落伞，但随后抛诸脑后。
When the rocket launched, there are flame generating under the tail of rocket engine, at the same time it generate a lot of smoke behind. The high temperature and high-speed flame and smoke are generated by the propellant burn.
火箭在发射时，火箭发动机尾部会产生尾焰，同时产生大量烟雾，火箭尾焰是推进剂燃烧后生成的高温、高速气体在喷管后形成的复杂湍流。
Triggers the smoke machine, the siren, the USB rocket launcher, and calls in the national guard.
让机器冒烟、触发警笛、USB火箭发射器，再把国民防卫队叫来。
Precision guidance has been widely used in modern warfare, as the rocket plume of smoke signal attenuation of the incident will affect the guided missile tracking, and identification for launch detection accuracy, therefore asked the Plume of the incident signal attenuation as small as possible.
精确制导广泛地应用于现代战争中，由于火箭发动机羽烟对入射信号的衰减，将影响到导弹的制导跟踪、连续发射和识别探测精度，因此要求羽烟对入射信号的衰减尽可能小。
I hardened my heart and took the smoke-rocket from under my ulster.
我硬下心肠，从我的长外套里取出烟火筒。
The rocket exhaust 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。
A column of smoke is established with a small rocket then photographed to determine movement of the trail.
烟柱是由一个小火箭放出的，然后摄影技求出烟迹的运动。
As smoke billowed below the rocket, her relatives gasped and her mother clasped her hands in front of her chest.
当火箭底部冒出滚滚浓烟即将升空时，安萨里的亲戚们都屏住了呼吸，她的妈妈双手紧握胸前。
Yet, from a hidden place a rocket shell shoots out, tailing with a long track of smoke. Then there is an explosion, and the broken track tails out behind the vehicle.
可是从看不见的处所，一生机箭弹拖着长长的烟迹飞来，爆炸，断裂的履带从车体后拖出。
