The Study on the Strategies of the Space Renovation of the Old Residential Buildings ——Take the Self-built Residence in Old City of Xiamen Port as an Example

厦港老城区的大量自建住宅，因其本身产权和自建的特殊性，容易成为被政府和规划所忽视的群体。然而，旧城区中数量上占据了绝对优势的自建住宅，也是亟待改善的群体。为了符合厦港严格的改造政策，也为了改善居民的生活质量，进行住宅内部空间的改造是相对可探讨的更新与改善方式。 论文第一章和第二章作为基础章节，绪论明确研究背景及意义，第二章对住宅改造节目的案例进行分析和对比，归纳并拓展总结出住宅空间改造的7个策略：结构修缮加固、舒适性改善（通风/采光）、布局合理优化、空间复合利用、提高储藏效率、适老化改造与旧物利用。 论文第三章和第四章作为核心章节，以厦港老城区的自建住宅为研究对象，对其历史演变、相关政策、...Owing to the particularity of property right and self-built traits, a large number of self-built residences in old city of Xiamen port are easily neglected by government and institute of land planning. However, the quantity of self-built residences occupies an absolute superiority, so it is urgent to make improvement. In order to conform with the strict renovation policy in Xiamen port and improve...学位：建筑学硕士院系专业：建筑与土木工程学院_建筑学硕士学号：2522014115175

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
