The essence of Anti-Japanese War life —Explore the uniqueness of Maodun’s Anti-Japanese War novels

抗日战争是中华民族历经百年沉沦，用鲜血和生命书写的壮丽画卷。国难当头，作家们在抗战救亡的旗帜下，创作了大量以宣传救亡为中心的文学创作，表现了抗战各个阶段的社会生活和思想变迁。茅盾是中国20世纪文学巨匠之一，他对抗战文学创作投入了极大的热情，并创作了大量与之相关的作品，展现了那一段特殊的社会历史风貌，做出了独到的贡献。然而，由于各种因素的影响，茅盾的抗战小说始终没有得到系统、深入的研究，仅有零星篇目或总体共性研究，值得进一步探索，以力求对茅盾文学创作面貌及抗战文学做出客观全面认识。 全文主要分为五个部分：绪论主要阐述本文的研究对象、研究内容、研究现状以及价值；第一章主要从小说题材的时代性、社会...After a hundred years of sufferings, Anti-Japanese War is a period is the grand picture painted by our blood and lives. When authors lived in a time of national calamity, they created a myriad of works themed on national salvation, demonstrating the transformation of lifestyles and thoughts in different phases of the war. Mao Dun is one of the greatest masters of 20th century Chinese literary. He ...学位：文学硕士院系专业：人文学院_中国现当代文学学号：1022011115226

以某综合性研究型大学的在校生及毕业五年内创业学生为调查对象,采用问卷调查及数据分析的方法。调查显示：男女大学生在校期接受创业实践教育机会均等,男女参与创业实践项目比例持平,但女大学生实施创业比例小于男生,持续创业比例远低于男生,女大学生在校创业与毕业后创业比例出现断崖式跌幅;男女大学生创业行业分布差异明显,女生主要集中于传统服务业、文化创意类、互联网类、公益创意类、教育培训类等,但相对其他研究行业分布相对全面、均衡

产量与经济效益共赢的高效生态农业模式:以弘毅生态农场为例

化学物质的大量投入以及元素不能循环导致农田生态系统退化,耕地质量和产量均呈下降趋势,食物链受到污染.本研究从低产田开始,通过秸秆养牛、腐熟牛粪还田恢复地力;以物理+生物方法控制虫害;以人工+机械管理杂草,停用农药、化肥和除草剂,同时不用地膜、人工合成激素、转基因种子生产优质安全食品,并在线上与线下销售.10年的长期实验结果表明,所在村庄农田生态环境改善,减少农药用量58.3%;物理+生物控虫效果明显,每盏灯年捕获量从2009年的33 kg下降到2014年的2.1 kg,下降93.8%;年消耗秸秆1000 t,秸秆利用率从1.1%提高到62.5%.有机肥还田提高了土壤生物多样性,有机果园蚯蚓数量317条m~(-2),而普通果园只有16条m~(-2);大量有机肥还田(75 t hm~(-2)),土壤有机质从实验初期的0.7%提高到2.4%.粮食产量从最初的11.43 t hm~(-2)提高到目前的17.43 t hm~(-2),其中冬小麦(Triticum aestivum)、夏玉米(Zea mays)、大豆(Glycine max(Linn.)Merr.)和花生(Arachis hypogaea Linn.)产量分别超出山东省平均水平42.6%,60.9%,32.2%和38.1%.由于质量好,产品已销售往除西藏以外的30个省、市、自治区,经济效益明显,平均每公顷效益是普通农田的3~5倍,带动所在村庄67户农民从事高效生态农业.本研究可为国家制定生态农业发展规划、精准扶贫、农村环境保护等提供科学依据

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

Prediction of Energy Resolution in the JUNO Experiment

International audienceThis paper presents the energy resolution study in the JUNO experiment, incorporating the latest knowledge acquired during the detector construction phase. The determination of neutrino mass ordering in JUNO requires an exceptional energy resolution better than 3% at 1 MeV. To achieve this ambitious goal, significant efforts have been undertaken in the design and production of the key components of the JUNO detector. Various factors affecting the detection of inverse beta decay signals have an impact on the energy resolution, extending beyond the statistical fluctuations of the detected number of photons, such as the properties of liquid scintillator, performance of photomultiplier tubes, and the energy reconstruction algorithm. To account for these effects, a full JUNO simulation and reconstruction approach is employed. This enables the modeling of all relevant effects and the evaluation of associated inputs to accurately estimate the energy resolution. The study reveals an energy resolution of 2.95% at 1 MeV. Furthermore, the study assesses the contribution of major effects to the overall energy resolution budget. This analysis serves as a reference for interpreting future measurements of energy resolution during JUNO data taking. Moreover, it provides a guideline in comprehending the energy resolution characteristics of liquid scintillator-based detectors
