Searches for exotica at LEP

The results of various searches for new physical phenomena beyond the Standard Model using data from the four LEP experiments are summarized. Topics presented include the search for flavour-changing neutral currents with single top production, compositeness leading to the production of excited leptons, and manifestations of extra dimensions.Comment: 5 pages, 3 figures, To appear in the proceedings of the 5th Rencontres du Vietnam on Particle Physics and Astrophysics, Hanoi, Vietnam, August 5-11, 200

Research of Regional Air Transportation Development Strategy in China

支线航空运输作为民航运输体系中重要的组成部分，其持续、健康、快速的发展无论对区域经济的推动，民航行业的发展，振兴我国航空工业乃至构建和谐社会等各个层面都具有重大意义。 然而，与我国民航运输总体的高速发展不相称的是，支线航空的发展却一直非常缓慢，徘徊不前。本文试图通过深入的分析和研究，从行业宏观角度及航空公司的微观角度揭示我国支线航空发展存在的问题及其根源，并有针对性地提出促进支线航空发展的策略建议。 本文首先以中外业界广为接受和认同的支线航空运输市场的界定标准为基础，结合我国国情和发展的观念对我国支线航空市场作出了界定。在此基础上，结合行业生命周期理论，通过研究欧美发达航空市场的支线航空发...As an important part of civil air transportation system, regional air transportation is the key to boost the regional economy; improve the civil air transportation industry; support the Chinese aviation manufacturing industry as well as build the harmonious society. However, unlike the fast development of the whole civil air transportation industry, regional air transportation develops very slowl...学位：工商管理硕士院系专业：管理学院工商管理教育中心（MBA中心）_工商管理硕士(MBA)学号：20031503
