您要查找的是不是:
- 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。
- 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。
- 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。
- This planet, unlike the other planets in our solar system, has an elliptical orbit and moves clockwise rather than counterclockwise. 这颗行星,不同在我们太阳系的其他行量,是椭圆形轨道,顺时针方向移动,而不是逆时针。
- It also occurred when the New Moon was near Perigee, the closest point to Earth in the Moon's elliptical orbit, making the Moon near its largest apparent size. 同时,新月正好处于近日点附近,也就是月球轨道上离地球最近的一点,又使得月亮的视尺寸接近最大。
- In fact, the Moon will reach its full phase within a few hours of perigee, the closest point in its elliptical orbit, making it the largest Full Moon of 2007. 事实上,在近地点(就是椭圆轨道上最接近地球的点)位置上,月球将在数小时内达到满月相位,从而形成了2007年最大满月。
- Because the Moon circles the Earth in an elliptical orbit, its angular size depends on how close the Moon is to closest approach (perigee) or furthest distance (apogee). 由于月球绕地球运行轨道为椭圆形,其视角的大小取决于月球在近地点或远地点如何程度的靠近或远离。
- 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.
- This total solar eclipse occurred near Aphelion, the point in Earth's elliptical orbit farthest from the Sun, and so the Sun was near its smallest apparent size. 这次日全食发生时,在太阳处于远日点附近,也就是地球轨道上离太阳最远的一点,所以太阳的视尺寸接近最小;
- 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。
- A theorem that the elliptical orbit parameters can be acquired by the latitudes and longitudes of flyer which flies around the earth with the gravitation is given and proved. 对于只受地球引力作用绕地球运动的物体;仅利用物体的经纬度.;就能唯一确定它的椭圆轨道参数。
