Research on Improvement of Bonded Logistics Business Operation of Firm C

随着我国外向型经济的蓬勃发展，保税物流作为现代物流的一个重要分支，其作用正日渐凸显，并且逐渐成为为我国外向型经济服务的主要物流运营模式。我国对外贸易总量高速增长，对外贸易的持续发展，国际供应链的物流需求不断提高，跨国企业经营有着巨大的发展前景，保税物流随之发展，但发展中存在的问题也愈发明显。保税物流作为一种连接国内物流和国际物流的纽带，作为一种基于国际贸易业务的新型物流形态，不断为国内外企业提供优质的服务，因此也成为中国物流实践运作中的一个重要的研究课题。 本文从C公司作为区域分销中心的保税物流服务提供商的角度出发来研究保税物流的运作。论文在分析和总结了国内保税物流和流程管理相关理论的基础上...With the vigorous development of Chinese export-oriented economy, ‘Bonded Logistics’, an important branch of modern logistics, plays more important role and becomes the main mode of logistics operation which services for the export-oriented economy. In addition, due to the high-speed growth and the continuous development of the Chinese foreign trade for many years, international supply chain logis...学位：工商管理硕士院系专业：管理学院_工商管理硕士(MBA)学号：1792011115080

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
