- NGEO MSS for narrowband mobile personal communications include voice,operating in LEO,medium-Earth orbit(MEO),or highly elliptical orbit(HECK)-also called Big-LEO. 非对地静止轨道移动卫星服务用于窄带移动个人通讯包括声讯;在近地轨道中地轨道(MEO)和高椭圆轨道(HECK)-又称为大劲地轨道运转.
- Subsequent observations and computations by other astronomers established, however, that Herschel's object was not a comet, which would have had a highly elliptical orbit. 不过,后来其他天文学家的观测与计算,证明业馀天文学家赫雪尔观察到的物事不是彗星。要是彗星的话,轨道会是个离心率很高的椭圆。
- Highly Elliptical Orbit Satellite 高椭圆轨道卫星
- If the bodies form too close together, their interactions with one another and with the gaseous disk can catapult them into new, highly elliptical orbits. 假如行星之间的距离太近,彼此的交互作用加上与气盘的作用,会将它们猛烈抛入非常扁的椭圆新轨道。
- High Elliptical Orbiting Scientific Program 高椭圆轨道运行科学计划
- Highly Elliptical Orbit 高椭圆轨道
- Deviating from a circular form or path,as in an elliptical orbit. 偏离轨道运行的偏离圆周轨道或路线,如椭圆轨道
- Deviating from a circular form or path, as in an elliptical orbit. 偏离轨道运行的:偏离圆周轨道或路线,如椭圆轨道。
- The engine operated for 63 seconds. The elliptical orbit was changed to a near circular orbit. 飞船变轨,变轨发动机工作了63秒,使原来的椭圆形接近圆形。
- If the satellite has an elliptical orbit, the result is a spiral wave, a miniature version of the pinwheel pattern of our galaxy. 如果卫星的轨道是椭圆的,就会产生螺旋波,就像是银河系纸风车形状的缩影。
- The moon travels in an elliptical orbit in relation to the equator, swinging back and forth over the northern and southern hemispheres. 月球在与赤道相对的椭圆形轨道上运行,往返于南北半球的上空。
- The spacecraft travels in a highly elliptical path that sweeps over the poles of the planet. 探测器的运行轨道是一个高偏心率的椭圆轨道,并且扫过金星的两极。
- LRO will then enter an elliptical orbit (called the commissioning orbit) from which it will move into its final orbit. 届时,LRO将进入一个椭圆形轨道(被称为试运行轨道),由此它将进入最终轨道。
- highly elliptic orbit 高度椭圆轨道
- The moon travels in an elliptical orbit in relation to the equator,swinging back and forth over the northern and southern hemispheres. 月球在与赤道相对的椭圆形轨道上运行,往返于南北半球的上空。
- It is a experiment to show when the gravitation act on the two planets, the two model planets will moves in an elliptical orbit. 万有引力演示:在万有引力状态下两星球的椭圆轨迹。
- A regional satellite navigation system which is made up of geosynchronous satellites and synchronous satellites with elliptical orbit is proposed. 摘要提出了一种用静止卫星和同步椭圆轨道卫星构造的区域卫星定位系统。
- An annular eclipse occurs instead of a total eclipse when the Moon is on the far part of its elliptical orbit around the Earth. 而发生日环食而不是日全食的是因为月亮运行到距离地球较远的轨道上,于是月亮的本影只能遮到太阳的中心。
- In fact, tonight's Moon reaches its full phase at 1637 UT, within only a few hours of perigee, the closest point in its elliptical orbit. 事实上,在美东时间16:37,月球在达到其椭圆轨道近地点的几小时内,月亮达到了最圆阶段。
- Explanation: This year Aphelion, the point in Earth's elliptical orbit when it is farthest from the Sun, occurs tomorrow, July 4th. 说明:地球将在明天(7月4日)经过今年的远日点,也就是地球椭圆轨道上离太阳最远的那一点。
