In Situ Uniform Lithium Enrichment for Dense, High‐Performance LLZO Solid Electrolytes
Rare Metals, Volume 45, Issue 1, January 2026.ABSTRACT A major challenge in garnet‐type Li7La3Zr2O12 (LLZO) system all‐solid‐state electrolytes is the high porosity that typically remains after sintering, which compromises ionic conductivity and degrades battery cycling performance. To address this, we propose an innovative strategy to achieve uniform lithium enrichment on the surface of ...

Shuitu Baochi Xuebao, 2007 在红壤丘陵区，对自然降雨条件下坡地（上层0～40cm，下层40～110cm）降雨壤中流产流过程进行了研究，结果表明：不同土地利用方式下，油茶林壤中流产流量大于同层恢复区；壤中流峰值流量恢复区大于同层油茶林；油茶林壤中流产流过程较恢复区开始早、结束晚。随着土层加深，滞后时间延长。同一土地利用方式下，产流量、峰值流量、滞后和拖尾均为上层小于下层。壤中流对降雨及地表径流的响应均为上层快于下层。不同的降雨类型，壤中流产流机理不同。峰值型降雨壤中流产流过程滞后时间较小，壤中流产流类型多为驱赶流。

Shuitu Baochi Xuebao, 2020 通过模拟室内风力、水力、冻融条件，进行单一水蚀、冻融+水蚀、冻融+风蚀+水蚀3种营力组合试验，揭示了复合侵蚀条件下的砒砂岩产流产沙变化规律。结果表明：（1）相同降雨条件下，冻融+水蚀、冻融+风蚀+水蚀试验的径流量均为水蚀试验的1.2倍，产沙量分别为水蚀试验的2.4，2.8倍。冻融能够增大砒砂岩产流产沙量，风蚀对增加侵蚀产沙量的作用较小。（2）砒砂岩产流产沙过程的峰值及变幅随营力种类的增多而增大，单一水蚀的产流产沙过程相较于复合营力作用下的水沙过程具有显著的坦化特征。（3）复合侵蚀作用使初始入渗率增加 ...

Shuitu Baochi Xuebao, 2021 横坡垄作是被广泛采用的保护性耕作措施之一。垄沟低洼处的积水可诱发壤中流，并可造成雨滴打击对土壤颗粒分离/搬运的增强与减弱作用并存。因此，横坡垄作坡面雨滴打击与壤中流交互作用对土壤侵蚀过程的影响有别于传统坡面。基于人工模拟降雨试验，对有/无雨滴打击作用（RI，WRI）自由入渗（FD）和壤中流（SP）2种试验处理下的产流、产沙过程进行了探究。结果表明：（1）径流量表现为SP+WRI > SP+RI > FD+RI > FD+WRI。雨滴打击作用和壤中流对径流的贡献分别为-47.09%~54.37%和41 ...

Rare Metals, Volume 45, Issue 1, January 2026.ABSTRACT Vanadium oxides are deemed competitive cathode candidates for aqueous zinc‐ion batteries (AZIBs), benefited from their high theoretical capacity and multiple crystalline structures. However, the sluggish reaction kinetics, poor reversibility, and high solubility have hindered the practical application.

Shuitu Baochi Xuebao, 2004 采用野外放水冲刷实验,对神府东胜煤田弃土弃渣侵蚀产沙规律进行了系统研究。结果表明:弃土弃渣堆积年限越短,可蚀性越大,侵蚀程度越强。经过4～7年的自然沉降过程,其表面的紧实度逐渐趋于稳定值。流量相同时不同下垫面条件下的产沙量1997年弃渣>1994年弃渣>煤渣>煤矸石。径流量、产沙量与放水流量呈线性关系,产沙量与径流量亦呈线性关系。集中的水流冲刷对弃土弃渣坡面造成严重的侵蚀,使含沙量保持在一个较高的水平,随着时间的变化含沙量出现剧烈的上下波动,总体上表现出逐渐减小的趋势,同时 ...

Shuitu Baochi Xuebao, 2016 利用黄土高原2种典型的土壤类型（黄土和塿土），在2个降雨强度（44.5，95.5 mm/h）和2个坡度（8.7%，25.9%）条件下进行了人工模拟降雨试验，研究了3种水质（去离子水、自来水、盐水）对坡面产流、产沙过程的影响。结果表明，2种土壤类型的产流过程差异显著，黄土条件下去离子水最先产流，但产流速率小于自来水与盐水；而塿土条件下去离子水的产流速率始终最大，自来水与盐水由于离子数量相当，产流速率差异较小。水质主要通过地表结皮的形成与发育影响径流，以总降水量45.5 mm为例 ...

Shuitu Baochi Xuebao, 2023 在贡嘎山原始森林不同土壤质地的样地采集制备原状土柱,监测并分析2020年夏季2场暴雨期间入渗出流过程及出流水稳定同位素(δ18O)变化特征。结果表明:(1)海拔2 649 m的富含砾石的粉壤土样地A在8月6日和8月11日次降雨后平均总出流量(分别为4.14,14.61 L)比海拔3 000 m的粉壤土样地B(1.45,11.99 L)大。样地A的出流过程对降雨的响应也更敏感。(2)出流水的同位素变化幅度小于降雨同位素变化幅度,入渗过程中新旧水混合强烈。(3 ...
