Shuitu Baochi Xuebao, 2011 土壤酶活性的高低可以直接或间接反映土壤肥力和土壤健康程度。研究选取烟台市黄务镇破坏山体周边7种植被恢复模式,测定土壤脲酶、多酚氧化酶、过氧化物酶、过氧化氢酶活性及土壤理化性质和细菌、真菌、放线菌数量。目的是探讨不同植被恢复模式对土壤酶活性的影响机制,为合理恢复植被提供参考依据。结果表明:不同植被恢复模式的土壤酶活性表现为0-10cm土层高于10-20cm土层;对土壤酶活性的改善作用为混交林>纯林>灌草丛,人工植被恢复模式中以黑松麻栎混交林最优;土壤酶活性具有显著差异 ...

Rare Metals, Volume 45, Issue 6, June 2026.ABSTRACT The poor soft tissue integration around titanium implants creates a microgap that serves as a pathway for pathogen invasion, resulting in infection, inflammation, and the progression of peri‐implantitis. As the implant’s transmucosal component, the abutment determines the degree of peri‐implant soft tissue attachment.

Dimensional Assembly Engineering of Ce‐MOF Interfaces for Selective Recognition of Phytic Acid
Rare Metals, Volume 45, Issue 5, May 2026.ABSTRACT Selective molecular recognition is central to chemical sensing yet discriminating structurally similar molecules at complex interfaces remains challenging. Traditional strategies based on tuning size, charge, or binding‐site chemistry often suffer from limited flexibility.

Rare Metals, Volume 45, Issue 5, May 2026.ABSTRACT The precise quantification of cytokines is crucial for monitoring disease onset and progression. Herein, we developed a synergistic signal amplification approach by utilizing nanoreactor‐encapsulated CeO2 nanozymes, which were in situ electrodeposited within the mesoporous silica nanochannel film (SNF) grown on indium tin oxide (ITO ...

Shuitu Baochi Xuebao, 2008 通过玉米秸秆腐解的培养试验,研究了土壤无机纳米粒子(SINP)对玉米秸秆腐解中磷酸酶、蛋白酶、脲酶和蔗糖酶活性的影响。结果表明:SINP加入腐解的玉米秸秆中后,对土壤中的酶活性有显著的影响,但这种影响因酶的种类不同而有显著的差异。SINP对所有磷酸酶(酸性、碱性、中性)活性都有提高作用,并以腐解的初期和后期提高的幅度最大和最显著。在初期和中后期也显著增加了腐解物中蛋白酶的酶活性。SINP对脲酶活性总体趋势具有显著促进作用。对蔗糖酶活性的促进作用在玉米秸秆腐解的前期非常明显,但在中后期起抑制作用。因此 ...

Rare Metals, Volume 45, Issue 5, May 2026.ABSTRACT The residue of mesotrione poses an increasingly serious threat to the environment and human health. Thus, it is essential to establish a platform that integrates rapid detection and efficient degradation. Covalent organic frameworks (COFs) materials have garnered significant attention owing to their designability.

基于旋耕玉米秸秆还田条件下土壤微生物、酶及速效养分的动态特征
Shuitu Baochi Xuebao, 2018 为研究旋耕条件下秸秆还田的腐解机理，设置不同数量秸秆还田处理，分别于玉米拔节期、抽雄期、乳熟中期、完熟期测定土壤微生物数量、土壤酶活性和速效养分含量。结果表明：（1）秸秆还田促进土壤微生物繁殖，提高土壤酶活性，增加碱解氮含量，降低速效磷和速效钾含量；秸秆量为11 250 kg/hm2时真菌、细菌、放线菌数量及蔗糖酶、纤维素酶活性增幅最大；秸秆量为7 500 kg/hm2时脲酶、磷酸酶活性和碱解氮增幅最大，速效磷、速效钾降幅最大。（2）部分土壤微生物数量与土壤酶活性之间存在相关性，播种后40天，土壤真菌 ...
