Research on Innovative Running Modes of Small and Medium-sized Travel Agencies in Xiamen at The Age of Mobile Internet ——Taking X Travel Agency As an Example

移动互联网的飞速发展，使得传统旅行社经营模式越来越难以适应市场发展的需要，中国的旅行社行业存在“散、小、差、乱”的问题，尤其是中小旅行社，受制于薄弱的资金实力、单一雷同的产品、低价竞争等种种因素限制，发展空间越来越小，因此要想在千变万化的市场发展中实现可持续化经营，中小旅行社进行经营模式上的创新就显得迫在眉睫，厦门中小旅行社也不例外。本文将在文献数据的搜集与实地调研的基础上，以厦门X旅行社为例，实证研究厦门中小旅行社的经营模式创新。 本文首先利用介观商务模式工具中的细分经营环境步骤，从平台环境、客户环境、伙伴环境、顶板环境和内部环境5个方面分析厦门市中小旅行社遇到的困难；其次，基于上述问题的...The rapid development of mobile Internet makes the traditional business running modesof travel agency be more and more difficult to meet the demands of the market . There areissueslike scattered distribution, small scale, poor servicequality and disorder for Chinese travel agencies,especially to those small and medium-sized ones, whose development space are getting smaller and smaller due to finan...学位：旅游管理硕士院系专业：管理学院_旅游管理硕士学号：1782012115117

3D ANALYSIS OF INSB SQUARE PATCH FILTERS WITH AR STRUCTURES IN THE THZ REGION

We investigate the transmission characteristics of THz filters with InSb square patches using the three-dimensional finite-difference time-domain method. To reduce the Fabry-Perot (FP) resonance, an anti-reflection coating (ARC) is introduced into the filter. It is shown that the use of a double-layer ARC reduces the FP resonance in the vicinity of the resonance frequency. Furthermore, we investigate the filters with a moth-eye structure. It is found that the FP resonance is appreciably reduced over a wide frequency range, compared to the filter with the double-layer ARC
