Research on Chinese Loanwords from Geographical Books of Xiao Fang Hu Zhai

《小方壶斋舆地丛钞》被誉为“清代舆地丛书之最”，为清末王锡祺辑录之大型地理丛书，其中收录了许多由奉派使臣、留洋学生、自由文人、天主教徒等出使异国或游历海外时所作的域外游记、行记、日记、随笔等。语料中含有大量晚清近代汉语外来词，其所具有的语言学价值自不待言。但《小方壶斋舆地丛钞》问世以来，仅为图书馆学、文学、地理学等资料梳理与背景介绍，并没有引起汉语学界的关注与研究。 首先，厘定汉语外来词在本研究中的概念范畴以及筛选标准，建立《小方壶斋舆地丛钞》晚清域外游记汉语外来词语料库。在此基础上，系统描写《小方壶斋舆地丛钞》汉语外来词来源语种、借用方式、语义类别、词法结构、书写形式等方面特点，并进行一系...Geographical Books of Xiao Fang Hu Zhai is the largest geography books by Wang Xiqi in Late Qing Dynasty.It includes overseas travels, notes, diaries, essays, etc,written by envoys, students studying abroad, freelancer,Catholics,etc.Its corpus contains a lot of Chinese loanwords in Late Qing Dynasty,which has a great linguistic value.But regarding Geographical Books of Xiao Fang Hu Zhai , there is...学位：文学硕士院系专业：人文学院_汉语言文字学学号：1022013115240

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
