The results show that high inclination circular high orbit(150 km or 200 km) has better performance,with its orbit lasting more than one yea...

大量的仿真计算表明，高倾角、圆轨道的中低轨(150 km或200 km)绕月飞行器具有相对稳定的轨道演化特征，在不进行任何调整的情况下，其轨道持续运行时间超过1 a。

To the quality of the 3 power of 10 kg satellite launched into a circular orbit near the ground, if produced by incomplete combustion of fuel, 1% of heat into a satellite in orbit at the time of kinetic energy, fuel quality test for m at least how much?

要把质量为10的3次方千克的卫星发射到地面附近的圆形轨道上，如果燃料完全燃烧产生的热量有1％转化为卫星在轨道上运行时的动能，试求燃料质量m至少为多少？

LRO's final orbit will be a circular polar orbit approximately 50 km above the Moon's surface (a little over 30 miles).

According to Sarkovskii's theorem, if the continuous self-map f of the closed interval has a 3-periodic orbit, then f must has an n-periodic orbit for any positive integer n But f can not has all n-periodic orbits for some n.

但f不可能有所有类型的n-周期轨。例如：则f仅有两种类型的3-周期轨中的一类。这表明Sarkovskii定理远远没有给出周期轨之间的关系的全部信息。

For a continuous map of trees or graphs to itself, we show the properties that every isolated chain recurrent point is an eventually periodic point, and an isolated chain recurrent point which is not in the orbit of a critical point and has no critical point in its orbit is a periodic point.

第三章主要讨论一些特殊连续统上连续自映射的孤立链回归点与最终周期点之间的关系，证明了对树或图上连续自映射，孤立链回归点是最终周期的，且如孤立链回归点不在临界点的轨道中，也无临界点在其轨道中，则此点必为周期的。

In the investigation of optical and magnetic properties of semimagnetic semi-conductors containing transition-metal ions, one electronic d-orbital should not be treated as a pure d-orbit, instead of a mixed orbit t2g or eg because of strong covalence.

在含过渡金属离子的半磁半导体的光学和磁学性质研究中，由于体系的共价性较强，d轨道不再是纯d轨道，而是混合轨道t2g或eg。

By setting symmetric orbit traps (in particular, by using more complex bounded sets, such as chaotic attractors, as orbit traps), visually fascinating images with cyclic or dihedral symmetry can be created in this way.

通过设置具有对称性的轨迹井(同时也把轨迹井推广到更加复杂的有界集上，如混沌吸引子)，生成具有循环群对称性的彩色图像。

Concretely speaking, using the irreducible tensor theory, we deuced the formulism for fine-structure energies of boron-like atoms in the ground and first excited states, which involves spin-orbit, spin-spin and spin-other-orbit interactions; completing all the angular integrations and spin summations needed, we make the final expression for fine-structure energies of boron-like atoms in the ground and first excited states in a combination of radial integrations. Afterwards, employing the wave functions we got in Chapter Three, we accomplished all the radial integrations and so obtained the fine-structure energies.

具体地说，利用不可约张量理论导出了类硼离子基态以及第一激发态的精细结构的表达式，给出了自旋-轨道、自旋-自旋、自旋-其它轨道相互作用等所涉及的所有角向积分和自旋求和的解析计算方法，完成了角向积分、自旋求和的计算，使类硼离子基态以及第一激发态精细结构能级最终可以表示为径向积分之和；在此基础上利用以前所得到的非相对论性波函数，进一步完成了所有径向积分的计算，从而得到了对应能级的精细结构的理论计算值。

First, we know that the planets all orbit close to the earth's orbit al plane, the ecliptic

首先，我们知道所有行星的轨道都很靠近地球的轨道平面――黄道面。

He became prime minister in 1997 and won international acclaim for his role in the Northern Ireland peace process.

他在1997年成为总理，并且因为在北爱尔兰的和平进程中发挥的作用受到国际社会的赞许。
