查询词典 orbit

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

LRO的最终轨道将是一个圆形极地轨道，离月球表面（略微超出30英里处）约50公里。

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。

The electron cloud of the highest occupied molecular orbit and the lowest unoccupied molecular orbit were calculated by Gaussian 03 software.

利用高斯03软件计算了此材料分子的最高分子占据轨道和最低空轨道上的电子分布情况。

This formation clearly depicts the elliptic orbit of a celestial body around the sun: we can conclude this from the fact that the sun is far out of the centre of the planetary orbit.

这形成清楚地描绘了一个围绕太阳天体椭圆轨道：我们可以得出一个事实，就是太阳，远远超出了行星轨道的中心这一点。

In the critical manoeuver, the orbit for Chandrayaan-1 was once again raised on Tuesday morning and now it is orbiting in an elliptic orbit which will take it right upto the moon.

在关键manoeuver ，轨道为月球- 1 ，再次提出星期二早上，现在是绕在一个椭圆轨道将采取正确达月球。11月8日，这是可能达到月亮的晚上。

The circulation, consumption and reproduction of the trilogy have not only testified to its historical significance and literariness, but also invested it with new meanings.

该三部曲的流通、消费与再生产不仅验证了其历史意义及文学性，而切还赋予它以新的意义。

If he thought that he could buy me off, he would be wrong.

如果他认为他可以收买我，那他就大错特错了。
