In the direct-location, with the precise model of satellite motion and its osculating parameters, a more accurate formula for the orbit calculation of satellite is obtained. Meanwhile, the determination of the position information of each pixel is more accurate with the precise model of earth shape.

二、直接定位中，通过建立精确的卫星运动轨道模型、卫星摄动模型，优选确定了卫星轨道计算公式，以提高卫星轨道计算精度；同时，采用对称椭球体的地球形态模型和融入卫星姿态的地面扫描点位置的计算方法，可使确定的地面扫描点的地理位置更精确。

The method also can be combined with J_2 invariant conditions and be described by osculating orbit elements.Finally,the results indicate that the formation drifts are greatly reduced with the optimized initial mean anomaly.And the drift of formations set up in osculating elements is decreased by(81.8681) percent,compared with that in mean elements,which proves the feasibility of this optimization design.

仿真算例表明：优化设计结果可以明显降低大椭圆轨道编队卫星的相对漂移量，与平根数描述的编队初始条件的设计结果相比，相对距离极大值点的漂移量降低约81.8681%，验证了基于主星平近点角初值的大椭圆轨道编队优化设计方法的可行性。

他比刚才更加像一个教师在想尽办法对付一个误入歧途但很有培养前途的孩子。

Insuring their reciprocal rights at performing spiritual moral onus, allowing them to regress natural life orbit, turning into social overmatches and defering to themselves free choice and self-shape, need social just consciousness and fair-and-square system at all.

确保道德典范在履行崇高道德义务的前提下获得相应的权利，让他们回归正常的生活轨道，成为社会的强者，并尊重他们自己的自由选择和自我塑造，需要全社会形成浓厚的公正意识、特别是有公正的制度保障。

" 26 Months, the Earth overtakes Mars on the inside track as they both orbit the Sun."

地球和火星都在各自的轨道围着太阳运转。

The most feature of the orbits of Near Earth Asteroids is that the semi major axes of the orbits are nearly equal to that of the Earth or the perihelia distances are approximate to or even less than the mean distance between the Sun and the Earth,thus they could move into inside of the Earth's orbit,so that th...

近地小行星轨道的最大特点是其轨道半长径与地球轨道半长径相近，或近日距离接近甚至小于日地平均距离，其运动可深入到地球轨道的内部，这将导致该类小行星与地球十分靠近甚至发生碰撞。

Because of the non-zero pretzel orbit in sextuploes, an effectivequadruploe field component is present in each sextuploe. And then it perturbs thelattice.

六极子与水平分离闭轨的耦合会产生附加的正四极场，从而扰动全环的Lattice参数，因此PRETZEL方案中六极子不但用来校正色品，还必须用来补偿其对Lattice的扰动。
