Gongye shui chuli, 2019 研究了高铁酸钾在污水预处理过程中对有机物的降解特性，考察了高铁酸钾投加量、反应时间和pH等因素对有机物降解效果的影响，采用荧光分析的手段，分析了高铁酸钾对水中不同类有机物的降解效果。研究表明，在酸性条件下，高铁酸钾投加量的增加更有助于有机物的降解，投加质量浓度增加到50 mg/L后，COD的降解不再有显著的变化。荧光分析表明，高铁酸钾对水中类酪氨酸、类富里酸类有机物均有较好的去除效果。

Structured machine learning modeling to support conservation of deep‐sea benthic biodiversity
Conservation Biology, Volume 40, Issue 4, August 2026.Abstract Biodiversity monitoring programs need to deliver accurate, timely, and actionable predictions. To establish a predictive monitoring program for deep‐sea benthos of the Santos Basin, Brazil, we developed a two‐stage structured model that allowed comparison of biodiversity predictions obtained from environmental simulations (2M‐Sim).

Evaluating synthetic substitutes to reduce illegal harvesting and support species recovery
Conservation Biology, Volume 40, Issue 4, August 2026.Abstract Providing synthetic substitutes is a widely promoted strategy to shift consumer demand away from wildlife products derived from threatened species. Yet, there is little evidence on whether product substitution prevents illegal or unsustainable harvesting and contributes to the recovery of threatened populations.

Conservation Biology, Volume 40, Issue 4, August 2026.Abstract Ex situ plant collections may be increasingly needed to protect representative samples of threatened or rare species and provide plant material for conservation translocation. A primary problem in these ex situ collections is loss of intraspecific variation due to plant death. Different management actions would be required depending on whether

Corporate Quasi‐Sovereignty: Big Tech and the Politics of Sovereign Authority in the Digital Age
Policy Studies Journal, Volume 54, Issue 3, August 2026.ABSTRACT As private technology firms expand their control over critical infrastructures, questions of sovereignty and governance are increasingly displaced from states to corporate actors. Existing scholarship on sovereignty assumes that authority is either monopolized by states or shared through institutionalized public–private arrangements.

Policy Studies Journal, Volume 54, Issue 3, August 2026.ABSTRACT Disruptive innovations often diffuse faster than inherited policy institutions can classify, assign jurisdiction, and govern them. In these early phases, the central struggle is often not yet about the stringency of substantive standards, but about prior questions of what the innovation is (its legal and administrative classification), who is ...

生物炭与有机肥、无机肥配施对采煤塌陷区复垦土壤理化性状的影响
Shuitu Baochi Xuebao, 2017 为了研究施用生物炭对采煤塌陷复垦土壤的熟化效果，以山西省晋城市采煤塌陷复垦区土壤为研究对象，连续3年采用生物炭与有机肥、无机肥配施等方式研究其对复垦土壤主要理化性状的影响。结果表明：不同施肥处理均不同程度改善了土壤的理化性状,有机肥配施生物炭处理明显降低了复垦土壤容重（降幅10%），提高了土壤孔隙含水率（增幅7.14%），但对土壤pH影响不明显。有机肥处理和无机肥处理的土壤全氮、全磷含量差异不显著；无机肥配施生物炭处理与单施无机肥处理相比，速效磷增加了8.33%，速效钾增加了6.34%，增幅较明显 ...
