Shuitu Baochi Xuebao, 2021 为探究不同生态修复模式对露天矿区排土场边坡产流产沙规律的影响，采用野外径流小区试验方法，对矿区排土场边坡不同生态修复模式的产流产沙进行了1个雨季的连续观测。结果表明：（1）研究区降雨年内分配不均，主要集中在汛期7—9月，该时期降雨量占到年均降雨量的77.03%，是年内径流泥沙损失最多的时期。（2）不同生态修复模式与对照（只撒播灌草种子）相比均具有减流减沙效果，但是不同生态修复模式的减流减沙效益有显著差异，减流效果从大到小依次为沙柳网格模式（64.35%）>生态棒模式（56.56%）>生态袋模式（52 ...

The Future of AI in the GCC Post‐NPM Landscape: A Comparative Analysis of Kuwait and the UAE
Politics &Policy, Volume 53, Issue 6, December 2025.ABSTRACT Comparative evidence of how two Gulf Cooperation Council (GCC) states translate artificial intelligence (AI) ambitions into post–New Public Management (post‐NPM) outcomes are scarce because most studies focus on Western democracies. To fill this gap, we examine constitutional, collective choice, and operational rules that shape AI uptake in ...

Shuitu Baochi Xuebao, 2018 探明径流小区尺度下不同水土流失治理模式的径流泥沙效应，对于大尺度水土流失治理具有重要意义。通过野外标准径流小区自然降雨试验探究了湘北红壤低山丘陵地带3种典型水土流失治理模式（S1模式：坡改梯+经果林，S2模式：等高沟垄+农作物，S3模式：平整撂荒坡面+草本）径流泥沙效应。结果表明：3种治理模式在次降雨诱导下平均径流量为S3（1.84 m3）>S1（1.03 m3）>S2（0.78 m3），平均泥沙流失量为S3（1.191 t/hm2）>S1（0.411 t/hm2）>S2（0.311 t/hm2 ...

Research on properties of PAD [PDF]
, 2016 随着LED亮度的不断提升和制程的不断优化，相同光效下芯片的尺寸越缩越小，芯片制造成本也不断降低，市场占有率不断扩大。因此，对于芯片可靠性的研究及不断改善逐渐成为了LED应用所面临的难点之一，尤其缺乏芯片长期老化失效的分析以及对芯片严苛使用环境下的失效模式的分析。 本论文通过GaN基LEDs芯片端金属电极（PAD）性能的研究，分析并改善了芯片端长期老化以及在严苛工作环境下的老化可靠性。同时，在此基础上设计了新的PAD降成本结构，降低了PAD端贵金属的耗量。本文的主要结论如下： （1）对于R-PAD结构 ...

Integrative Conservation, Volume 4, Issue 2, Page 254-267, June 2025.Our research demonstrates that in mirroring prevailing human biases towards different insect groups, LLM chatbots oversimplify insect diversity by predominantly restricting “bees” to honeybees and “wasps” to yellowjackets, neglecting the majority of biodiversity that includes wild bees and parasitoid wasps, while also favouring Nearctic species in ...

Is the US Moving Toward Autocracy? A Critical Assessment
Politics &Policy, Volume 53, Issue 3, June 2025.ABSTRACT Using the theory of incremental autocratization, I illustrate in this commentary that recent developments in the United States perfectly align with this theory. In the analytical framework I use, incremental autocratization consists of six distinct step: (1) societal turmoil, (2) a proposition of radical change, (3) an electoral victory as ...

Shuitu Baochi Xuebao, 2006 对元谋干热河谷区4种旱坡地生态农业模式的水土保持效益进行了系统的研究。结果表明：与对照模式“罗望子＋裸地”相比，建立的4种模式均体现了良好的水土保持效果，其中．“罗望子＋木豆＋柱花草”模式截持降雨。增加地表盖度．改善土壤物理性状，提高蓄水保水能力，防治水土流失效果最佳，其余3种模式均有明显的生态效益。根据需要．若重新对套入模式的主栽灌草层作物进行科学合理的搭配，重建后的优化复合生态农业模式，无论是生态效益，还是经济和社会效益都将得到充分的体现。
