But while higher is better from a fuel conservation perspective, there is an upper limit on how high it is safe to orbit humans for long periods.
越高耗费的燃料越少，而载人飞船能够长时间安全飞行的轨道高度就有上限。
To counteract its orbital drag, mission controllers must use propellant in attached spacecraft to periodically loft the station to a higher orbit.
为了抵消其轨道牵引力，任务控制中心必须使用f飞船自带的推进器定期将其推进到一个更高的轨道。
China's shrapnel, created in a higher orbit, could be around for a century to come.
中国的碎片是在更高的轨道上形成的，可能需要一个世纪才能落回来。
Each year, the Moon steals some of Earth's rotational energy, and USES it to propel itself about 3.8 centimeters higher in its orbit.
每年，月球都会偷取地球的部分转动能，让自己在运行轨道中的位置升高大约3.8厘米。
The aim would be to push the debris further towards the earth where it would burn up, or into a higher but safer orbit.
其目的是将碎片进一步推向地球，在那儿它会燃烧起来，或推到一个更高的，但更安全的轨道。
Once the collision is over, the orbits return to their normal shape, and electrons have to absorb energy to stay in the new higher orbit.
碰撞一旦结束，轨道就恢复到正常的形状，而电子必须吸收能量才能保持在新的高轨道上。
When the atom absorbs energy from light, one electron may move to a higher energy orbit, leaving an unpaired electron.

When navigation accuracy is highly expected , the sensor with higher accuracy should be chosen and the observation time should be longer , especially in high - altitude orbit.
当对导航精度要求较高时，轨道越高，尤其在高轨道类型中，应尽可能的选择精度高的敏感器以及尽量长的观测时间。
The actual directivity of the detector which is possessed in the space orbit perhaps is higher than that obtained in the experiment system on the ground.
探测器在轨测量时的实际准直性可能比在地面实验中所测得的准直性更好。

骨髓外浸润、眶内及皮肤浸润多见，肾功能损害、高钙血症、淀粉样变性的发生率较高。
The first kind of disturbance influences the communication more than the second kind because the geostationary communication satellite is located in the orbit 36000 kilometers higher than equator.
由于同步轨道通信卫星位于距离地球36000公里的赤道上空，因此长距离的线运动干扰与角运动干扰相比，其扰动作用显得微乎其微。
