查询词典 elliptical orbit

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，今晚的月亮将在世界时间16点37分达到满月相位，仅仅是月球在到达近地点数个小时之后，月球位于近地点时，其椭圆轨道距离地球最近。

The natural satellite of Earth, visible by reflection of sunlight and havin满月 g a slightly elliptical orbit, approximately 356,000 kilometers (221,600 miles) distant at perigee and 406,997 kilometers (252,950 miles) at apogee.

月亮，月球：地球的天然卫星，通过反射太阳光而发光，并有一个略呈椭圆形的轨道，在近地点时，距离约有356，000公里221，600英里），在远地点距离约有406，997公里(252，950英里）。

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。

Magnetospheric MultiScale mission design needs spacecrafts flying in a regular tetrahedron configuration about the apogee of an elliptical orbit.

Magnetospheric MultiScale任务利用椭圆轨道远地点附近的正四面体航天器编队，协同完成对地球磁层结构和动力学特性的测量和分析。

The line that passes through the center of the Earth linking the perigee and apogee, known as the line of apsides, itself rotates in the orbital plane at a speed that depends on the geometry of the elliptical orbit and the inclination of the orbital plane to the equator.

经过地球中心，连接近地点和远地点的线称为apside线，卫星在轨道平面上以某个速度旋转，这个旋转速度根据椭圆轨道以及轨道平面到赤道的倾角的几何学来计算。

The first two extra flights were deep-space missions, with C taur boosting the spacecraft into an elliptical orbit with an apogee of some 80,000 kilometers to study navigation and reentry problems.

最先 增加的两次飞行属于深层太空任务，利用森托尔将飞船送人远地点为大约8万千米的椭圆型轨道以研究导航和重返大气层等问题。

The configuration stability of the elliptical orbit satellite constellation requires the stabilization of the ascending node right ascension, the argument of perigee and the mean anomaly at the same time.

椭圆轨道星座构型稳定性要求同时实现升交点赤经、近地点幅角和平近点角的稳定。

Because of the secular perturbation variations of the ascending node right ascension, the argument of perigee and the mean angle caused by the initial deviations of the semi-major axis, the inclination and the eccentricity are linear time-variant, then the active biases of the semi-major axis, the inclination and the eccentricity can realized the self-stabilization design of the elliptical orbit satellite constellation, and so the configuration stability will be improved.

通过初始偏差对椭圆轨道卫星的长期影响分析可知，轨道半长轴、倾角和偏心率的初始偏差对升交点赤经、近地点幅角和平近点角的长期摄动变化是线性的，因此通过主动偏置轨道半长轴、偏心率和倾角能够实现椭圆轨道星座构型的自稳定设计，从而提高其构型稳定性。

Avebury Manor of July 15, 2008 reminds us that the Mayan Long Count calendar will end on December 23, 2012: by showing precise orbital locations for all nine planets of our solar system on that date, plus an accurate elliptical orbit for Pluto

埃夫伯里庄园的2008年7月15日提醒我们，玛雅长的计数日历将於2012年12月23日结束：显示我们在那个日期的太阳系所有九个行星的精确轨道地点，加上准确的椭圆形轨道的冥王星

Then, the orbit of the Moon about the earth could be a consequence of the gravitiational force, because the acceleration due to gravity could change the velocity of the Moon in just such a way that it followed an orbit around the earth.

如此说来，月球的轨道应该是地球引力的结果。因为引力产生的加速度会改变月球的速度，使它按一个绕地轨道运转。
