The diverse populations of icy bodies of the outer Solar System (OSS) give critical information on the composition and structure
of the solar nebula and the early phases of planet formation. The two principal repositories of icy bodies are the Kuiper
belt or disk, and the Oort Cloud, both of which are the source regions of the comets. Nearly 1000 individual Kuiper belt objects
have been discovered; their dynamical distribution is a clue to the early outward migration and gravitational scattering power
of Neptune. Pluto is perhaps the largest Kuiper belt object. Pluto is distinguished by its large satellite, a variable atmosphere,
and a surface composed of several ices and probable organic solid materials that give it color. Triton is probably a former
member of the Kuiper belt population, suggested by its retrograde orbit as a satellite of Neptune. Like Pluto, Triton has
a variable atmosphere, compositionally diverse icy surface, and an organic atmospheric haze. Centaur objects appear to come
from the Kuiper belt and occupy temporary orbits in the planetary zone; the compositional similarity of one well studied Centaur
(5145 Pholus) to comets is notable. New discoveries continue apace, as observational surveys reveal new objects and refined
observing techniques yield more physical information about specific bodies. 相似文献

A survey of current knowledge about Jupiter, Saturn, Uranus, Neptune, Pluto, and their satellites is presented. The best available
numerical values are given for physical parameters, including orbital and body properties, atmospheric composition and structure,
and photometric parameters. The more acceptable current theories of these bodies are outlined with thorough referencing offering
access to the details. The survey attempts to cover the literature through May 1, 1972.

Ion optics are crucial components of ion thrusters and the study of the different ion extraction solutions used since the beginning of the electric propulsion era is essential to understand the evolution of ion engines. This work describes ion engine grids' main functions, parameters and issues related to thermal expansion and sputter erosion, and then introduces a review of ion optics used for significant launched and tested ion thrusters since 1970. Configurations, geometries, materials and fabrication methods are analyzed to understand when typical ion thrusters use two or three grids, what are the thicknesses and aperture sizes of the screen, accelerator and decelerator grids, why molybdenum and carbon-based materials such as pyrolytic graphite and carbon–carbon are the best available options for ion optics and what is the manufacturing method for each material. 相似文献

大到整个飞机机身,小到某个飞机附件,周转时间都是十分重要的。在成本、质量和速度的三角关系中,后者正在占据越来越重要的地位。现在航空业出现一种新趋势,即航空公司在寻找维修公司时更注重维修周转时间的长短,以前,却是更为注重维修价格的高低。随着飞机营运费用的升高,周转 相似文献

一直以来,航空公司大多采用ACARS通信系统(飞机通信寻址和报告系统)进行空中通信服务.但与陆地通信系统相比,该系统的传输速度慢而且成本高,成为目前影响飞行数据传输速度的重要因素之一.一些MRO软件供应商已开始开发机载无线通信系统,试图改善以往缓慢、昂贵和复杂的空中无线服务,使飞行中生成的重要维修数据以更低的成本、更快的速度和更高效率实现传输. 相似文献

Corotating interaction regions (CIRs) in the middle heliosphere have distinct morphological features and associated patterns
of turbulence and energetic particles. This report summarizes current understanding of those features and patterns, discusses
how they can vary from case to case and with distance from the Sun and possible causes of those variations, presents an analytical
model of the morphological features found in earlier qualitative models and numerical simulations, and identifies aspects
of the features and patterns that have yet to be resolved.
