查询词典 orbit

For the orbit estimation algorithm based on the measurement of the geomagnetic field vector,when measurement data influenced by outliers,filtering advents deviation,convergence becomes slow and even diffuses.

近地轨道由于有丰富的地磁场资源，且具有相当好的地磁场模型，可以采用高斯球谐函数来描述地磁场模型，这样磁场的强度和方向是位置的函数，因此能采用磁测的方法对卫星进行定轨导航[1，2]。

In order to cut the reconstructed 3D models in computer aided virtual surgery,a cutting algorithms for 3D surface model in medical images is proposed.By using the mouse to draw an enclosed curve on the model,the bistouries cutting orbit is simulated,which implements the arbitrary mutual cutting in surgery process.

为了在计算机辅助虚拟手术中对重建的三维模型进行切割，提出一种医学图像三维表面模型切割算法，利用鼠标在模型上画任意形状的封闭曲线来模拟手术刀的切割轨迹，从而实现手术过程中的任意交互切割。

As a show of power, the Empire destroyed three Mon Calamari cities from orbit.

为了展现他们的武力，帝国由卫星轨道毁灭了三个蒙克莱梅利星上的城市。

The idea was two decades ahead of its time, and helped to attach his name to the geostationary orbit above the equator. In 1962, at the chilliest part of the cold war and just after the launch of Sputnik had heralded the space age, he discussed in "Profiles of the Future" the implications of transatlantic satellite radio and television broadcasts, with information raining down on previously isolated parts of the world.

他在20年前就萌发了这个想法，也是这个想法让他把名字贴到了围绕赤道的地球同步轨道上。1962年，也就是爆发冷战最严重的那一年，继Sputnik 人造卫星的成功发送开启了太空世纪后不久，他在《未来的轮廓》一书中探讨了卫星广播和电视广播横渡大西洋的应用，他认为它们将使信息降落到原先与世隔绝的那些地方。

The idea was two decades ahead of its time, and helped to attach his name to the geostationary orbit above the equator. In 1962, at the chilliest part of the cold war and just after the launch of Sputnik had heralded the space age, he discussed in "Profiles of the Future" the implications of transatlantic satellite radio and television broadcasts, with information raining down on previously isolated parts of the world.

这一设想足足超前了20年，环赤道同步静止轨道也因此以他的名字命名。1962年，冷战正酣，苏联的人造卫星发射揭开了空间时代的序幕，克拉克写下了《未来掠影》一文，描述了他用越洋卫星广播甚至电视节目将全世界的各个角落连结成一体的设想。

The idea was two decades ahead of its time, and helped to attach his name to the geostationary orbit above the equator. In 1962, at the chilliest part of the cold war and just after the launch of Sputnik had heralded the space age, he discussed in "Profiles of the Future" the implications of transatlantic satellite radio and television broadcasts, with information raining down on previously isolated parts of the world.

这个想法领先于那个时代20年，环赤道同步静止轨道也因此以他的名字命名。1962年，冷战时期，苏联的人造卫星发射揭开了空间时代的序幕，他在上畅谈跨越大西洋卫星电视广播的想法，将信息撒播向早前那些各自孤立的世界。
