roll spin

The parent will sometimes roll and spin round before you in such a dishabille, that you cannot, for a few moments, detect what kind of creature it is.

母鸟在你们面前打滚，打旋子，弄得羽毛蓬松，使你一时之间不知道它是怎么一种禽鸟了。

That day Boeing 737 got into a spin, made a barrel-roll, did some dives and happily got out, then experienced both engines fail, but succesfully glided down to the major airport.

那天波音737旋转、翻滚、几次跳水和幸运脱离，随后飞机引擎失灵，但最终成功滑翔到主要机场。

Meanwhile, it also discusses the influence of roll yaw on sideslip in spin, and of moving round plumb line on angle of bank.

同时就尾旋中偏滚对尾旋侧滑的影响、绕铅垂轴旋转对坡度的影响等进行了讨论分析。

The simulation algorithms of wave high, yaw force, rolling moment and sway moment were put forward. Meanwhile, it also discusses the influence of roll yaw on sideslip in spin, and of moving round plumb line on angle of bank.

给出了随机海浪波高、横荡力、横摇力矩、艏摇力矩的仿真算法。同时就尾旋中偏滚对尾旋侧滑的影响、绕铅垂轴旋转对坡度的影响等进行了讨论分析。
