, 2006 一种中药活性成分与DNA相互作用的研究方法，其特征在于采用微透析取样技术与高效液相色谱联用的技术。具体包含如下步骤：分别将待研究的中药提取液和DNA溶液，及待研究的中药提取液和不含DNA的空白溶液混合形成均相的混合体系，微透析取样并收集反应透析液和空白透析液；在相同的条件下分别进行高效液相色谱分析；将上述分析获得谱图进行比较，相对于空白透析液相色谱，峰面积减小的为待研究的中药提取液中能够和 DNA分子发生相互作用的活性成分，峰面积没有发生变化的为不能够和 DNA分子发生相互作用的成分。本方法操作简便易行，

Rare Metals, Volume 45, Issue 11, November 2026.ABSTRACT The separation of light olefins is a crucial process in the petrochemical industry, and developing advanced adsorbent materials is very significant. Aluminum (Al) cluster‐based heterometallic frameworks possess great application prospects but have rarely been investigated for separation applications.

, 1992 本文提出并证明了不可压缩剪切层流中对流-扩散相互作用结构不变性诸定理:即二难剪切层流与其线性化及非线性扰动存在同一的对流-扩散相互作用结构,且物理尺度(指时间、空间和速度尺度)相同。给出十个推论,例如:对流-扩散相互作用可在剪切层流及其扰动场内“激发“快时间尺度和小空间尺度结构,线性化稳定性原理的约定对剪切流体系统成立等。应用题例导出计及时间-空间尺度效应和非平行流效应的广义Orr-Sommerfeld(GOS)方程,证实它有两个粘性解:阻尼层解和干扰层解;经典OS方程及其两个粘性解 ...

Rare Metals, Volume 45, Issue 11, November 2026.ABSTRACT Powder metallurgy (PM) near‐α Ti alloys are often constrained by a pronounced strength–ductility trade‐off, due to the coarse lamellar microstructure formed during the sintering process. To address this issue, a thermomechanical route combining cyclic hot rolling with short‐time solution treatment was developed to improve the mechanical ...

, 1985 藻类种群之间的相互作用是调节群落组成和演替的生物学因素。它往往是通过胞外活性物质调控其它藻类或生物类群生长、代谢的潜在生物学途径。蓝藻是水、土等生态系统中的重要成员，因此，对蓝藻不同种群之间相互作用的研究是十分重要的。为了了解蓝藻种群之间的相互关系，作者选取了两种固氮蓝藻Anabaena variabilis 1058和Tolypothrix tenuis在实验室条件下进行实验。在混合培养条件下，T. tenuis和A.

World Food Policy, Volume 12, Issue 2, November 2026.ABSTRACT This study explores environmental justice issues in coastal food systems, focusing on conflicts between small‐scale fisheries and the energy sector due to differing goals in managing food and energy sources. It does so by examining the interdependence between institutions, policies, and different types of knowledge; key elements in building ...

World Water Policy, Volume 12, Issue 4, November 2026.ABSTRACT This article examines how renewable‐energy expansion is changing water–energy bargaining among Iran, Iraq, and Türkiye in the Tigris–Euphrates basin. Much of the existing literature on transboundary water politics focuses on territorial control, upstream–downstream power asymmetries, legal rules, and hydro‐hegemony but gives less attention to ...

Functional Ecology, Volume 40, Issue 11, Page 3606-3623, November 2026.Read the free Plain Language Summary for this article on the Journal blog. Abstract Flowers with deep corollas are frequently associated with nectar robbing, a behaviour that often reduces pollen transfer and seed production. Robbing scars, however, may further affect plant reproductive success through rainwater entry into corolla tubes.
