Design and Implementation of Collaborative office system for Bureau Organs

近年来，随着社会的发展，企业规模的逐渐壮大，以个人为单位的工作模式已不能满足瞬息万变的市场形势。只有将工作细化，发挥团队作用，协同工作，才能快速响应市场变化，在竞争中取得胜利。工作流技术的提出为实现了业务流程的自动化管理、信息在人与人之间流转、跨地域、跨部门的用户可协同工作提供了有力的手段。 本文基于J2EE、SSH框架和Oracle10g数据库设计并实现了一套局级办公系统，涵盖了公文、事务、会议和系统管理四大功能模块，重点解决了困扰本局的信息沟通不流畅，跨地域基本靠电话，无法实时了解工作进度，全凭个人主观意识主动汇报，无据可依、无据可查等关键难题。针对以上功能设计实现了该系统，并展示了关键...In recent years, with the development of the society, the scale of enterprises is gradually growing, and the working mode of an individual as a unit is unable to meet the changing market. Only elaborated work plan, good team work and collaborating work together, can quickly respond to market changes to win the competition.

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
