| 1. | Orbital calculation of g spectral type globular clusters in the galaxy
型球状星团的轨道计算 |
| 2. | Calculation of the hybridization orbital of single - wall carbon nanotubes
单壁碳纳米管杂化轨道计算 |
| 3. | It is also used for the difference between the observed position of an object ( minor planet or comet ) and the position calculated from an orbit
该术语也用于描述观测的某天体（小行星或彗星）的位置与轨道计算值之间的差别。 |
| 4. | Because of this , a set of satellite orbital elements very rapidly " ages " and for accurate predictions must be updated every few days
所以，人造卫星的轨道计算数据会很快就过期，如果你要准确计算它们的轨道，你就必须即使更新它们。 |
| 5. | The main function of orbit calculation is to simulate the flight procedure of spacecraft , before that , the dynamics model of orbit must be established
轨道计算主要用来模拟飞行器的飞行过程，前提是建立动力学模型。由于空间问题的复杂性，造成了动力学模型的多样性。 |
| 6. | We believe it was programmed to automatically descend if control was ever cut off from the surface . we have calculated the solg ' s course of descent from its previous orbit
我们确信其程序设定为一旦和地面联系被切断,卫星将自动坠入大气层.我们已经根据其先前的运行轨道计算出了solg的坠落路线 |
| 7. | The orbit simulation program mainly concentrates on orbit calculation . this thesis first introduces the fundamental knowledge of orbit dynamics , including orbit perturbation and spacecraft attitude control
轨道仿真程序核心部分是轨道计算，本文首先介绍了轨道动力学基础，包括轨道摄动问题，以及飞行器姿态控制等基础知识。 |
| 8. | Unlike comet and asteroid orbital elements which can be reliably used for many months , satellite orbits are constantly changing due to both orbital maneuvering by the satellite and the effects of atmospheric drag
小行星和彗星的轨道计算数据可以使用数月，但是人造卫星不行，因为它们的轨道会随时被人造卫星自己或者大气阻力所修正。 |
| 9. | The " length of track calculation " section of the dialog allows you to choose the length of the displayed ground track ; you can either display a track for a single orbit of the object , or you can manually enter the length of the track , and the interval at which positions are to be calculated
“轨道计算的长度”用于选择需要显示的地面轨迹的长度；你可以选择绕地一周的地面轨迹，也可以通过输入相应的轨道长度来显示在一个时间段内的轨道地面轨迹。 |
