, 2013 微生物的硝化与反硝化作用是人工湿地脱氮的主要途径,如何调控与优化湿地沿程溶解氧浓度和污水碳氮比,对于提高人工湿地脱氮效果至关重要。为此,在人工湿地前端埋设曝气管、后端增设碳源投加管,构建了一种人工湿地强化脱氮系统,并选择曝气速率、曝气运行/停止时间比、碳源投加量、进水方式进行正交试验,开展了人工湿地碳氧联合调控脱氮研究。结果表明,各因素的影响大小依次为:曝气运行/停止时间比>曝气速率>碳源投加量>进水方式;最优运行条件为:曝气速率为2.5 L·h-1,曝气运行/停止时间比为8 h/16 h ...

Rare Metals, Volume 45, Issue 3, March 2026.ABSTRACT NiFe‐based MIL‐55 metal‐organic frameworks (MOFs) face challenges in achieving atomically precise composition and reliable methods for uniform growth. This study addresses these challenges by applying a slow evaporation crystallization technique to crude colloidal MIL‐55 products from hydrothermal synthesis, resulting in highly uniform ...

European Policy Analysis, Volume 12, Issue 1, Winter 2026.ABSTRACT What is the role of policy entrepreneurs in promoting the design of public administrative reform? We present a conceptual framework for assessing the influence of policy entrepreneurs on public administrative reform. We start by proposing a typology of the various policy entrepreneurs active in the administrative reform arena.

Rare Metals, Volume 45, Issue 2, February 2026.ABSTRACT Achieving a simultaneous enhancement of strength and ductility remains a critical bottleneck for the large‐scale and cost‐effective engineering application of magnesium alloys. In this work, guided by first‐principles calculations, we tailored the τ‐Mg32(Al,Zn)49 phase and optimised twin boundary, thereby designing and successfully ...

Test and Research on the Rheological Damage Properties of Sandstone under Dynamic stress field-Seepage field coupling [PDF]
, 2016 机械振动、交通荷载、地震等产生的动应力场与降雨等因素所产生的渗流场耦合，会加快软岩的流变损伤，导致滑坡、崩塌、泥石流等严重的地质灾害。因此，加强对动应力场-渗流场耦合作用下软弱岩体的动态流变损伤特性的研究具有重要的理论和实际意义。论文以软弱砂岩为研究对象，利用重庆大学煤炭灾害与控制国家重点实验室的RLW-2000M煤岩三轴流变试验机研究了砂岩在动应力场-渗流场耦合作用下的动态流变损伤特性。具体的研究内容如下： (1)通过采集-钻芯-切割-打磨-浸泡等过程制备饱和的砂岩试样，根据砂岩试样的全应力 ...

Rare Metals, Volume 45, Issue 2, February 2026.ABSTRACT The high accuracy in surface‐enhanced Raman scattering‐lateral flow immunoassays (SERS–LFIAs) is critical for reliable point‐of‐care testing (POCT) in clinical diagnostics. Conventional approaches are often affected by sampling variability and uneven distribution of immunoprobes, leading to unreliable signal fluctuations.
