地球引力

Then the orbit of a satellite with perturbations (including the nonspherical perturbation, the solar and lunar gravity, the solar radiation pressure and the drag of atmosphere) is simulated. The observations of SINS and GPS are derived from the orbit.

然后在考虑地球扁率、大气阻力、日月引力、光压等摄动力的影响下仿真出了卫星标准轨道，在此基础上仿真出SINS、GPS的测量信息。

The five earthquakes appeared on the first or fiftwwnth day of the lunnar month alternatrly and were the syzygial earthquakes in group which showed up most concnentrativrly in the Chinese seismological history.

对地球而言，太阳月亮是最密切的天体，太阳的光与热是地上万物生命之能源，其引力维持了整个系统的整体运行。

Earth's gravity has caused the Moon to become tidally locked us as well as increasing the distance between the two worlds.

地球的引力造成了月球潮锁，也增加了两个世界之间的距离。

This is not due to global warming but the natural effect of our Earth being dragged towards the sun, causing our beloved salt waters to just boil away.

&但这并不是全球变暖导致的，而是太阳对地球的引力造成的，这种自然效应将把我们深爱的海水都蒸发干。&

As their light zips across billions of light-years to Earth, the gravity of matter along the way stretches, splits, and contorts their images.

这是因为当它们发出的光线跨越数十亿光年到达地球的时候，其图象可能会由于沿途的物质引力作用而被拉伸、撕断或扭曲。

The gravitational pull of all the other heavenly bodies deflects the satellite from its orbit and it has to be controlled from Earth very systematically and painstakingly to keep it in the orbit.

在引力的所有其他天体推卫星从轨道和它必须从地球控制系统和非常艰苦，以保持它在轨道上。

The moon gravitates to the earth, but is held in its path by opposing forces from other bodies in space.

月球为地球所吸引，但由于宇宙空间中其他天体相反的引力，月球保持了固定的轨道。

The site, from the Department of Earth Science, Rice University, Houston, Texas, USA provides age of the ocean crust, satellite gravity, topography, earthquake epicentres and recent volcanism maps for downloading for teaching purposes.

本网站属于美国休斯敦Rice大学地球科学系，提供了洋底壳的年龄、卫星引力、地形、地震震源、近期火山地图的教学资料，可供下载。

Here you can experience the super-smooth shooting pleasure of flying, bullets of different functions (laser beam, shot, the shock wave), and 4 bullets to upgrade systems on different planets based on real data generated by gravity, as well as seven different brilliant boss The bullets, flame on the distant Venus, Saturn on the meteorite stream, Neptune ice and other natural airflow phenomenon, as well as fine human beings on earth houses, you have little doubt about how to include 59K of space such a large content through a small cell phone, the nine planets in You wrote the immortal legend bar

在这里你可以体验超级流畅的飞行射击快感，功能不同的子弹，以及4级子弹升级系统，不同行星上根据真实数据产生的引力，以及七大不同的boss绚丽的子弹，遥远金星上火焰、土星上陨石流、海王星冰气流等自然现象，以及地球上人类精细的房屋，你会怀疑小小59K空间如何包含如此庞大的内容通过小小手机，在九大行星上写下您的不朽传说吧

David Helfand: Several ideas have been proposed: throwing up nuclear weapons at them, throwing at the satellite that gravitationally tugs its way a little bit, so its orbit changes ever so slightly just enough to miss the Earth as it whizzes past.

大卫·赫尔方：人们提出了好几种方案，比如发射核武撞击小行星，或者利用人造卫星的引力使小行星轨道发生轻微偏移，这样就能保证它们高速掠过时只是与地球&擦肩而过&而不会撞上。
