地月空间术语词典
地月空间的研究横跨轨道力学、制导导航与控制、任务设计、空间环境建模好几门学科,术语天然跨学科;不少关键概念又出自 Gateway、CAPSTONE 以来近十几年的英文文献,散在论文与报告里。读到 NRHO、不变流形、弱稳定边界这些词,往往要先翻几篇文献才弄清它指什么、怎么用、与相邻概念差在哪。本词典要把这道门槛拆掉:每条术语不止给一句释义,而是讲清定义、补上背后的数学与力学、给出工程上关心的参数与数字、辨析易混的变体,并为每处判断标出文献出处,做到能拿来读论文、做轨道设计。词条按八个主题分类,也可经侧边栏与搜索直达。

Perturbed manifolds extend the transfer phase range beyond the two fixed points of natural zero-cost trajectories.)

The paper divides the Halo orbit into 360 equally-spaced nodes, each a potential injection point.)

In the strongly nonlinear phase space around Halo orbits, standard differential correction tends to diverge or converge to large-impulse trajectories. Backstepping search progressively reduces the correction step size until the iteration escapes the erroneous region and finds a solution satisfying the termination condition, improving convergence robustness.)

说明
- 词条的目标是把一个术语讲到能用:先给定义:先给定义,再补数学与力学细节、工程参数与任务实例,必要时辨析易混变体,最后列相关概念与参考文献;每处判断尽量标到具体文献,可追溯。
- 中文版收录全部条目,是英文版的翻译底本;英文版逐步镜像,未译条目随后补齐。
- 词条末尾的相关概念互相链接,可顺链从一个术语扩展到相邻概念。
