我国航空公司机票价格博弈分析

主要从博弈论完全信息条件下"囚徒困境"的角度,以及完全信息条件下有先后定价次序的价格竞争角度分析我国民航业的双寡头航空公司机票价格定价策略,然后从不完全信息混合博弈角度分析航空公司与民航总局监管博弈,最后根据以上论证对民航总局管控和航空公司机票定价策略提出相关建议。     

在飞行中女飞行员的机组配合

安全是民航飞行永恒的主题。作为安全最直接的保障者和消灭事故的最后防线是飞行员,他们肩负着巨大的压力。保证安全不只是某个飞行员的责任,而是整个机组的责任。只有在科学高效的机组配合条件下,才能充分发挥整个机组的潜力,最大限度地保障飞行安全。飞行员一直是男性占主体,随着民航、军航女性飞行员的加入和成长,飞行机组的配合方式有所改变,这里主要探讨飞机飞行过程中女性飞行员加入以后机组配合的特点,及如何在实际中提高异性机组配合能力。     

通用航空飞行数据采集技术初探

飞行数据在航空运输业的多个领域内都有非常重要的应用,但极少有通用航空单位对飞行数据进行采集及分析。通用航空的飞机大部分都是小型飞机,现代飞行数据采集技术并不完全适用于通用航空,因此实时监控及飞行品质监控和维修预测很难进行。本文对现代飞行数据采集技术进行了分析探讨,提出了适合通用航空飞行数据的音、视频采集技术。     

The Composition of Cosmic Rays and the Mixing of the Interstellar Medium

The differences between the composition of Galactic cosmic rays and that of the interstellar medium are manifold, and they contain a wealth of information about the varying processes that created them. These differences reveal much about the initial mixing of freshly synthesized matter, the chemistry and differentiation of the interstellar medium, and the mechanisms and environment of ion injection and acceleration. Here we briefly explore these processes and show how they combine to create the peculiar, but potentially universal, composition of the cosmic rays and how measurements of the composition can provide a unique measure of the mixing ratio of the fresh supernova ejecta and the old interstellar medium in this initial phase of interstellar mixing. In particular, we show that the major abundance differences between the cosmic rays and the average interstellar medium can all result from cosmic ray ion injection by sputtering and scattering from fast refractory oxide grains in a mix of fresh supernova ejecta and old interstellar material. Since the bulk of the Galactic supernovae occur in the cores of superbubbles, the bulk of the cosmic rays are accelerated there out of such a mix. We show that the major abundance differences all imply a mixing ratio of the total masses of fresh supernova ejecta and old interstellar material in such cores is roughly 1 to 4. That means that the metallicity of ∼3 times solar, since the ejecta has a metallicity of ∼8 times that of the present interstellar medium.     

中国大型运输机的发展

Aircraft manufacturers always try to do new aircraft on an old basis. A300 is the basis of A380. It is very important for China to own a basis-one type of Chinese own commercial large transport. Trying to find some enlightenment from A380,for Chinese regional aircraft such as ARJ21, ERJ145 and other commercial large transports. Simultaneously,the opportunities and challenges to China Civil Aviation Industry are also discussed in this paper.

基于SPSS因子分析的舰载机航材保障风险因素分析

为做好舰载机航材保障风险管理工作,必须对其可能存在的风险因素进行深入、细致的分析,查找出其关键风险因素并研究风险因素之间的关系。因此,文章在依据舰载机航材保障风险因素初步识别结果的基础上,通过调查问卷的方式,归纳总结出21个舰载机航材保障风险因素,并利用SPSS统计软件和因子分析法对调查问卷的结果进行分析和计算,最终提炼出具有代表性的7个公共因子,从而完成了舰载机航材保障关键风险因素的确定和分类。     

Clusters of Galaxies: Beyond the Thermal View

We present the work of an international team at the International Space Science Institute (ISSI) in Bern that worked together to review the current observational and theoretical status of the non-virialised X-ray emission components in clusters of galaxies. The subject is important for the study of large-scale hierarchical structure formation and to shed light on the “missing baryon” problem. The topics of the team work include thermal emission and absorption from the warm-hot intergalactic medium, non-thermal X-ray emission in clusters of galaxies, physical processes and chemical enrichment of this medium and clusters of galaxies, and the relationship between all these processes. One of the main goals of the team is to write and discuss a series of review papers on this subject. These reviews are intended as introductory text and reference for scientists wishing to work actively in this field. The team consists of sixteen experts in observations, theory and numerical simulations.
