拉格朗日点 meaning in Chinese
lagrangian point
Examples
- A solar - sail driven spacecraft , parked at the lagrangian l1 point between earth and the sun , might be the perfect mission , and answer , to this crucial dilemma
一个由太阳帆驱动、停泊在地球与太阳之间的第一拉格朗日点的飞船，作为对此种窘境的解决方案，会非常适合此项任务。 - This lagrange point is a place in space where the earth ' s and the sun ' s gravity roughly balance to provide a point of near - equilibrium where a spacecraft can maintain its position while expending almost no energy
这个拉格朗日点是空间中地球与太阳的引力大致平衡的一处地点，在这个地方的宇宙飞船几乎不需要消耗能量就能维持其位置不变。 - There would be no way to repair and upgrade this telescope , though ? it would be placed in an inaccessible orbit around the so - called second lagrangian point , where the earth , the sun and the moon orbit one another while remaining in the same position relative to each other
然而韦博望远镜将无法得到维修和更新，因为它将被设置在一个无法达到的轨道（在所谓的第二拉格朗日点附近，在一点上地球、太阳和月亮相互围绕运转，但却保持相对不变的位置） 。 - More and more researches have shown that most of the intense geomagnetic storms are caused by fast coronal mass ejections in interplanetary space ( icmes ) . though the ace satellite can provide solar wind data in almost real time for prediction of geomagnetic storms , the time interval is too short ( shorter than 30 - min ) for effective predictions of major geomagnetic storms
位于拉格朗日点的ace卫星可以提供近实时的太阳风数据，但依据ace卫星太阳风数据进行地磁暴预报，时间的提前量非常有限，对于大地磁暴，这个时间提前量往往不超过30分钟，这样的时间提前量对于实际应用来说，是不能令人满意的。 - There are five points in space , called lagrangnian points l1 to l5 , where the gravity of the sun and earth exactly cancels out each other . objects residing at these points are in some sort of gravitational equilibrium . more intriguingly , probes can orbit about these lagrangnian points even if no object is present there
以太阳和地球为例，太阳和地球之间的重力在5处不同的地方刚好互相抵消，称为拉格朗日点l1 - l5 ，物体可以停留在拉格朗日点中而不受重力影响，即使点中没有物质，物体也可以围绕拉格朗日点公转。
