Policy Studies Journal, Volume 50, Issue 1, Page 111-142, February 2022., 2022 This paper contributes to the integration of the study of multiple (i) spatial scales, (ii) resource systems, and (iii) points in time in natural resource governance by introducing a strategy of layering action situations. In the Institutional Analysis and Development Framework, action situations can be studied singularly, in comparison, or as networks

Gongye shui chuli, 2022 为了解决市政废水生物脱氮过程中碳源不足的问题，利用多循环序批式反应器（MCSBR）建立了基于混合生物膜和悬浮污泥的主流同步短程硝化反硝化工艺。重点考察了温度对生物膜、悬浮污泥短程硝化和反硝化效果的影响，并分析了低温条件下同步短程硝化反硝化的可行性。周期实验结果表明，在好氧阶段，NO2--N无显著上升，而总氮明显下降，且无明显的NO3--N积累，说明MCSBR内发生了同步短程硝化反硝化。随着温度的降低，氨氧化和反硝化容积负荷均呈下降趋势，但混合体系氨氧化活性始终低于其反硝化活性 ...

Gongye shui chuli, 2008 序批式生物膜反应器(SBBR)在好氧条件下能创造缺氧微环境,出现同步硝化反硝化现象。为在城市污水处理中实现持久稳定的同步硝化反硝化过程,研究了DO、C/N、温度和pH对SBBR同步硝化反硝化的影响。结果表明:DO是影响同步硝化反硝化重要因素,温度和pH对硝化菌和反硝化菌的生物活性具有明显的抑制作用,在中性和略偏碱性时可较好地实现同步硝化反硝化。

Gongye shui chuli, 2018 在定向驯化高效稳定硝化污泥的基础上，研究了各因素对硝化系统启动及硝化活性的影响。结果发现，以丝状椰壳与珍珠岩作为固态发酵的基质时，椰壳与珍珠岩的体积比为1∶2、含水率为55%左右时，硝化污泥固态发酵菌剂的硝化活性最高。硝化系统启动阶段接种硝化菌剂，硝化系统启动时间由未接种处理的18 d缩短到14 d。接种硝化菌剂可强化正常运行硝化系统的硝化活性。

Journal of Healthcare Engineering, Volume 2018, Issue 1, 2018., 2018 A terminology (or coding system) is a formal set of controlled vocabulary in a specific domain. With a well‐defined terminology, each concept in the target domain is assigned with a unique code, which can be identified and processed across different medical systems in an unambiguous way.

Rare Metals, Volume 45, Issue 8, August 2026.ABSTRACT The electrocatalytic co‐reduction of CO2 and nitrate (NO3− ${\text{NO}}_{3}^{-}$) to synthesize urea presents a sustainable alternative to traditional industrial processes, yet its efficiency is fundamentally limited by the kinetically mismatched activation and coupling of CO2 and NO3− ${\text{NO}}_{3}^{-}$.
