this area may be over flown by the Space Shuttle for descending node de-orbits and landings at the Kennedy Space Center
对于使用降交点脱轨和在佛罗里达州肯尼迪航天中心着陆的航天飞机,它们就很可能会飞越这些地区
For geocentric and heliocentric orbits, the ascending node (or north node) is where the orbiting object moves north through the plane of reference, and the descending node (or south node) is where it moves south through the plane.
對地心和日心軌道,稱為升交點(或北交點)的是軌道上的天體運行到參考平面北側時通過點,而降交點(或南交點)則是天體運行至南側時通過的點。
These vectors are generally used to match the orbital inclination of another celestial body or craft, and the only time this is possible is when the current craft's orbit intersects the orbital plane of the target - at the ascending and descending nodes. To match the orbital inclination, either perform an anti-normal burn at the ascending node or a normal burn at the descending node.
这两个向量主要用于与另外一个星体/飞船进行轨道倾角对齐。 而执行这个操作的最佳时机则是当飞船位于两者轨道平面的交线处。 要与目标轨道倾角对齐,可以在升交点对准轨道平面反面法线设置加速,或在降交点对准轨道平面法线设置加速。
The points at which Pluto's orbit tilts strongly towards the ecliptic plane passing from south to north (ascending node), and from north to south (descending node).
对于黄道面,描画出大幅倾斜轨道的冥王星,从南向北通过黄道面的点和从北向南通过的点。
for shuttle purposes, this means that atmospheric entry is never planned for descending node orbits for high-inclination flights
对于完成航天飞机的太空穿梭任务来说,这就意味着从来没有在计划中考虑过如下的安排:对于降交点轨道,让航天飞机以具有大倾斜坡度的飞行轨迹再入大气层
With respect to the effect of earth albedo on solar array output current of sunsynchronous orbit satellite, the solar array output current is analyzed for different local times of descending node, and is modeled by taking the dawndusk orbit satellite as a research object. Estimation of earth albedo is modeled too. By use of the least square method, both models are used to estimate current parameters and earth albedo coefficients with different orbit height satellite telemetry in different seasons.
针对地球反照对太阳同步轨道卫星太阳电池阵输出电流的影响,首先比较不同降交点地方时卫星的太阳电池阵输出电流,分析其变化规律,然后选定晨昏轨道卫星作为研究对象,建立太阳电池阵输出电流模型与地球反照系数估计模型,利用最小二乘法估计电流参数与地球反照系数,最后结合不同季节、不同轨道高度卫星的遥测数据进行在轨验证。

If eclipses of the sun and moon formed part of Mithraic symbolism, they could also represent the ascending and descending nodes where the Moon crosses the ecliptic.
如果太陽和月亮的蝕相是形成了密特拉密教象徵的一部分,祂們也能夠代表著月球穿越過黃道上升和下降的兩個交點。
Most astrologers see these points as being of karmic significance: The ascending or northern node is said to represent the spiritual development called for in this life, while the descending or southern node represents experience gathered during previous lives.
大多数的占星家视其具有与因果业力相关的重大意义:月亮的上升点(或北交点)被认为是代表今生灵性成长上的召唤,而下降点(或南交点)则代表着过去世的经验累积。
From the tree diagram, one can see that a simple descending traversal through the nodes can quickly create a rendered SQL statement, as we'll see in greater detail in the section on statement compilation.
从树形图中,人们可以看到,通过一个简单的降穿越节点可以快速创建一个呈现的SQL语句,我们会看到更细节一节中的语句编译。
So attendants Cautes and Cautopates are supposed to represent the stations of sunrise and sunset respectively, or perhaps the spring and autumn equinoxes, or equivalently the ascending (spring) and descending (autumnal) nodes of the Sun's apparent path on the celestial sphere.
所以這伴隨的神靈考泰斯與考托佩斯被認為應該分別代表著日出和日落的位置,或者也許是春天和秋天的分點(換句話說為春分、秋分),或者是相当于太陽在天球上明顯路徑上升(春季)以及下降(秋季)的交點。
In the above steps, we calcuate the number of consensus nodes as Count, and take validators from the candiate list ranked by votes in descending order. When candidates is not enough, it will be supplemented from StandbyValidators. Finally, the consensus nodes are determined.
在上面的步骤中,根据投票情况确定了共识节点个数 Count ,再根据申请验证人的投票进行降序排序,取前 Count 个。若申请的验证人不足时,则从备用共识节点进行补充,最后得到当前参与共识的验证人,即议员。
