气提式反应器中气液传质的初步研究

, 1984
本文对内径D=0.186m,中心管内径D_c=25mm的气提式反应器,在液体无净流量,变化气流量和中心管高度的条件下,用化学法测定了气液相界面积,用物理解吸法测定了液侧体积传质系数,并借文献数据对测定结果作了解释。实验中,用电导法测量了反应器内各区的气含量值 ...

Adding the Farmer Domain to Aquifer Recharge: Insights From Smallholder Farmers' Natural Water Retention Measures in the Danube–Tisza Interfluve, Hungary

World Water Policy, Volume 12, Issue 4, November 2026.
ABSTRACT This paper describes and analyzes recharge practices in Bács‐Kiskun County, Hungary, within what can be categorized as the farmer domain. Such locally embedded aquifer recharge practices remain underexplored in Hungary. Current research and funding largely focus on large‐scale Managed Aquifer Recharge (MAR) interventions emphasizing intended ...

张力腿平台有限振幅运动的方程和数值解

, 2007
论证了张力腿平台（TLP）在波浪作用下发生有限振幅运动时，所受惯性力、粘性力、浮力等载荷不仅与波浪场有关，还与瞬时响应有关，是响应的非线性函数；张力腿拉力也是各自由度位移的非线性函数．所以分析唧受力时必须考虑平台的瞬时加速度、速度和位移，在瞬时位置建立运动方程．据此推导出TLP发生有限振幅运动时的外力计算公式，建立了TLP 6自由度有限振幅运动非线性控制方程．其中考虑了由6自由度有限位移引起的多种非线性因素，如各自由度之间的耦合、瞬时湿表面、瞬时位置等；还包括自由表面效应、粘性力等因素引起的非线性 ...

Evolving Contexts and Diverging Strategies: Federalism and the Politics of Immigrant Welfare Exclusion in the US

Policy Studies Journal, Volume 54, Issue 4, November 2026.
ABSTRACT The intersection of immigration and welfare has taken a central stage in the politics of social policy and garnered increasing scholarly attention in welfare politics research. While prior research has examined how immigration affects welfare support and welfare generosity in the US, less is known about the determinants of immigrant‐related ...

多元统计方法在节肢动物群落分析中的应用

, 2013
近年来有关节肢动物群落的研究报道较多,而传统的、简单的多样性指数分析远远不能满足对高通量群落数据的挖掘。采用多元统计方法可以较好地分析群落数据。其中,在研究某一处理的长期效应时,主响应曲线是一种经典的多元分析方法;而非度量多维尺度分析具有能处理较大量的数据且常能以低维排序图反映结果的优点,是一种具有广泛应用前景的排序技术。本文以Bt棉与非Bt棉不同比例混作棉田的节肢动物群落为例 ...

Epistemic Capabilities of Artificial Intelligence for Public Administration and Policy Research: A Framework for Scholarship in the Age of Intelligent Machines

Policy Studies Journal, Volume 54, Issue 4, November 2026.
ABSTRACT Artificial intelligence (AI) has gained much interest in public administration and public policy fields in recent years. Research on and that uses AI has so far treated it as an object or context within the broader administrative and governance discourse.
