Gaoya dianqi, 2019 为了探索混合气体中SF6分解产物的检测技术,了解不同背景气体对SF6分解产物检测结果的影响,文中对比研究了CF4/SF6、N2/SF6等不同混合气体与纯SF6为背景气体条件下,SO2、H2S、CO等SF6分解产物检测结果的差异,研究表明,不同背景气体对SF6分解产物的检测结果影响不同,文中通过分析拟合得出了CF4/SF6、N2/SF6混合气体对SF6分解产物的检测结果的影响系数,并建立了几种CF4/SF6、N2/SF6混合气体为背景气体与纯SF6为背景气体条件下SF6分解产物转换的数学模型。

Functional Ecology, Volume 40, Issue 5, Page 1415-1427, May 2026.Read the free Plain Language Summary for this article on the Journal blog. Abstract Wildfires are disrupting and regenerating forces in nature that affect all ecosystem components. However, the impact of wildfires on soil multitrophic biodiversity and the resulting consequences for ecosystem multifunctionality (EMF) remain poorly understood.

Gaoya dianqi, 2021 SF6的强温室效应对全球气候的潜在影响已经引起了人们的高度担忧,对SF6进行降解是处理SF6的一种有效手段。文中基于填充床式反应器（PBR）,针对系统中H2O浓度对降解SF6的影响进行了研究,并从降解效率与产物两个角度进行了分析。研究结果表明H2O能够在PBR中产生大量的OH与H自由基,这些活性自由基能够与SF6的初级分解产物进行次级反应从而促进其分解,提高了其降解率。实验发现,当SF6体积分数为2%时,最有利于促进SF6降解的水汽浓度为1%,其降解率达到95.69%。同时 ...

Jellyfish blooms restructure plankton dynamics and trophic linkages in coastal waters
Functional Ecology, Volume 40, Issue 5, Page 1443-1460, May 2026.Read the free Plain Language Summary for this article on the Journal blog. Abstract Jellyfish blooms are increasing globally in frequency and intensity, introducing complex ecological interactions, yet the mechanisms by which they alter ecosystem structure remain poorly characterized due to a lack of sustained field observations.
