However, the flight still managed to return 139 seconds of aerodynamic data at a velocity between 17 and 22 times the speed of sound, Darpa said.
然而，Darpa表示，在以17到22倍音速飞行的状态下，飞机还是回传了139秒的空气动力学数据。
Pendulum return, loop-the-loop, escape velocity.
钟摆回摆；转圈圈；逃逸速度。
For the maximum velocity, I'm suggesting that you give your encouragement to someone who can't return the favor-it's a distinction that won't be lost on the recipient.
我建议以最快的速度鼓励不能给予回报的人——这样才不会失信于人。
The designed mechanism can make the output part get uniform velocity in the working area and better quick return character. It is more suitable ford…
使所设计机构能实现输出件在工作区间内完全等速，且具有较好的急回特性，比传统的六杆急回机构能更好地满足实际应用中的不同需求。
