圆形轨道 meaning in English
circuit orbit
circular orbit
Examples
- On the holonomy invariance of a circular orbit in the nut - taub - like spacetime
时空中圆形轨道完整不变性的研究 - Shenzhou - 5 flew in a circular orbit 343 kilometres above the earth
神舟五号飞船在距地球343公里的圆形轨道上飞行。 - Before it can return any science , though , it will take six - months to adjust its extremely elongated 35 - hour long orbit to a circular one two - hours long using atmospheric friction
然而在它发送回任何科学资料前,飞船大概需要6个月时间利用大气摩擦将伸长的35小时轨道调整为一两小时的圆形轨道 - Because the controller is easy to get the position of rotor by the encoder , we can continuously rotate the flux of the armature rotor by applying spwm method to the control system . the continuous rotation of the flux of armature make the output torque of motor has no ripple
由于通过编码盘可以轻易获得精确的电机转子位置信号，故运用spwm调制方法可以使得无刷机的电枢磁场按照圆形轨道连续旋转，从而实现输出转距无脉动。 - This dissertation established a novel distributed spaceborne sar simulation system based on the high level architecture ( hla ) . this dissertation developed a mathematical model of instantaneous sphere earth model and instantaneous circle orbit model for the geometry system between the satellite platform and the targets on earth based on the satellite platform ’ s orbit features and sar system ’ s operational characteristics , unlike the traditional sphere earth model and circle orbit model
本文从建立精确的、易于仿真的星地几何关系入手,舍弃了传统的星载sar研究中的球型地球模型和圆形轨道模型,根据星载sar的轨道特点和sar的工作特点,对局部球型地球模型进行改进,建立了在瞬时球型地球模型和瞬时圆形轨道模型下的星载sar仿真。
