固原县农业建设方针的探讨

该成果从合理利用自然资源出发，对固原县的自然、社会经济特点，农业生产，发展的历史和现状等，进行了大量艰苦细致的调查研究和科学分析，对该县农业建设方针，提出了科学性、方向性的意见；并帮助该县制定了全县农业、林业建设区划。同时对该县小流域的规划以及全县土壤培肥改土、抗旱增产措施、水土流失的概况和防治都提出了具体意见。该成果分析了固原发展农业生产的有利条件和不利条件，指出了该县在农业建设中存在的主要问题，论述了改变该县不利局面，实行“以牧为主”的方针，客观依据及其实施步骤；并指出当前应实行“大力造林种草，兴牧促林，农林牧全面发展”的方针及采用草灌先行等过渡措施。该成果受到宁夏回族自治区政府的高度重视。固原县已按此成果所提意见安排了全县三年调整时期的生产部署。这项成果，不仅对固原县的农业建设有指导作用，而且对黄土高原的农业建设有重要的实用价值

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
