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

The effects of ocean acidification on marine organisms and ecosystem

海洋酸化是CO2排放引起的另一重大环境问题.工业革命以来,海洋吸收了人类排放CO2总量的三分之一.目前,海洋每年吸收的量约为人类排放量的四分之一(即约每小时吸收100万吨以上的CO2),对缓解全球变暖起着重要的作用.然而,随着海洋吸收CO2量的增加,表层海水的碱性下降,引起海洋酸化.海洋酸化会引起海洋系统内一系列化学变化,从而影响到大多数海洋生物的生理、生长、繁殖、代谢与生存,可能最终导致海洋生态系统发生不可逆转的变化,影响海洋生态系统的平衡及对人类的服务功能.地球历史上曾多次发生过海洋酸化事件,伴随着生物种类的灭绝,其内在联系虽然不甚明确,却也可能暗示未来海洋酸化可能对海洋生态系统产生重大的影响.Ocean acidification is known as another global change problem caused by increasing atmospheric CO2.Since the industrial revolution, the oceans have absorbed more than one third of the anthropogenic CO2 released to the atmosphere, currently, at a rate of over 1 million tons per hour, totaling to about one quarter of all anthropogenic CO2 emissions annually.Uptake of CO2 by the ocean has played an important role in stabilizing climate by mitigating global warming.However, rising ocean carbon levels caused by the uptake of anthropogenic CO2 (acidic gas) leads to increased ocean acidity (reduced pH) and related changes in ocean carbonate chemistry, or "ocean acidification".Recent research has shown that ocean acidification affects the physiology, growth, survival, and reproduction of many, if not most marine organisms.Ultimately, future ocean acidification may lead to significant changes in many marine ecosystems, with consequential impact on ecosystem services to societies.Several ocean acidification events are known to have occurred during Earth’s history, each coinciding with high rates of species’ extinctions.Although the mechanisms involved in past massive species extinction associated with ocean acidification events, they certainly hint potential disastrous impacts on ecosystem functions in short future.中国科学院“百人计划”(2006-067); 国家自然科学基金(40872168)资

塔克拉玛干沙漠腹地大气气溶胶中游离氧化铁的测定[J]

大气沙尘气溶胶中铁氧化物含量的测定对研究气溶胶吸收特性有重要的研究意义。采用柠檬酸盐-重碳酸盐-连二亚硫酸盐(CBD)和漫反射光谱法(DRS)对塔克拉玛干沙漠腹地塔中站2006年4月9～11日沙尘暴天气过程前后TSP沙尘样品中的游离氧化铁进行定量和半定量研究,研究得出,塔中游离氧化铁占全铁含量的变化范围在4.55%～8.16%之间(平均值6.36%),全铁占样品总量的5.16%,游离氧化铁占样品总量的0.32%;反射光谱一阶导数曲线峰值在435和560 nm对针铁矿和赤铁矿具有识别指示意义

JUNO Sensitivity on Proton Decay p→νˉK+p\to \bar\nu K^+ Searches

The Jiangmen Underground Neutrino Observatory (JUNO) is a large liquid scintillator detector designed to explore many topics in fundamental physics. In this paper, the potential on searching for proton decay in $p\to \bar\nu K^+$ mode with JUNO is investigated.The kaon and its decay particles feature a clear three-fold coincidence signature that results in a high efficiency for identification. Moreover, the excellent energy resolution of JUNO permits to suppress the sizable background caused by other delayed signals. Based on these advantages, the detection efficiency for the proton decay via $p\to \bar\nu K^+$ is 36.9% with a background level of 0.2 events after 10 years of data taking. The estimated sensitivity based on 200 kton-years exposure is $9.6 \times 10^{33}$ years, competitive with the current best limits on the proton lifetime in this channel

JUNO sensitivity on proton decay p → ν K + searches*

The Jiangmen Underground Neutrino Observatory (JUNO) is a large liquid scintillator detector designed to explore many topics in fundamental physics. In this study, the potential of searching for proton decay in the $p\to \bar{\nu} K^+$ mode with JUNO is investigated. The kaon and its decay particles feature a clear three-fold coincidence signature that results in a high efficiency for identification. Moreover, the excellent energy resolution of JUNO permits suppression of the sizable background caused by other delayed signals. Based on these advantages, the detection efficiency for the proton decay via $p\to \bar{\nu} K^+$ is 36.9% ± 4.9% with a background level of $0.2\pm 0.05({\rm syst})\pm$$0.2({\rm stat})$ events after 10 years of data collection. The estimated sensitivity based on 200 kton-years of exposure is $9.6 \times 10^{33}$ years, which is competitive with the current best limits on the proton lifetime in this channel and complements the use of different detection technologies
