粘流-无粘干扰流动(IF)理论

open access: yes, 1990
对不可压缩层流二维干扰流动,本文提出一个干扰流动(IF)理论。IF理论要点为:1)干扰流动沿主流的法向被分为三层即粘性层、干扰层和无粘层,引进了法向动量交换为主导过程的干扰层概念。2)利用力学守恒律、三层匹配关系及文中引进的干扰模型,把三层的空间尺度及惯性-粘性诸力的数置级表示为单参数m的函数 ...

Wildfire strengthens the relationship between soil biodiversity and ecosystem multifunctionality in subtropical forests

open access: yesFunctional 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.

Robust metrics for quantifying and comparing resistance and recovery in experimental studies

open access: yesMethods in Ecology and Evolution, Volume 17, Issue 1, Page 6-14, January 2026.
Abstract Various indices have been developed to experimentally quantify resistance and recovery (two components of engineering resilience) in response to anthropogenic and natural disturbances. This diversity complicates the selection of appropriate metrics for comparing resilience across ecosystems and studies.

Aridity and grazing are associated with reduced trait complementarity and higher invasion intensity of Solanum rostratum in native plant communities

open access: yesFunctional Ecology, Volume 39, Issue 11, Page 3255-3268, November 2025.
Read the free Plain Language Summary for this article on the Journal blog. Abstract The biotic resistance hypothesis (BRH) of Elton posits that diverse communities are more resistant to biological invasions. While the effects of climatic stresses and human disturbances on community invasibility have been extensively studied individually, their combined

Structural design of highly permeable Bi2O3 microspheres decorated by Pt‐nanoparticles: facile synthesis and acetic acid sensing performance

open access: yesRare Metals, Volume 44, Issue 9, Page 6417-6425, September 2025.
Graphic abstract Abstract Real‐time detection of acetic acid vapor is of concern for ensuring environmental and personal safety. However, acetic acid gas sensors, particularly those based on Bi2O3, often fail to meet practical performance requirements owing to their slow response characteristics and high operating temperature.

干扰素联合利巴韦林对慢性丙型肝炎患者血脂谱和胰岛素抵抗的影响

open access: yesZhongguo shiyan zhenduanxue, 2017
HCV感染不仅引起慢性肝炎、脂肪肝、肝硬化和肝癌等疾病,还可影响糖、脂代谢引起代谢性疾病[1]。干扰素(IFN)联合利巴韦林是慢性丙型肝炎抗病毒干预的标准方案之一。有报道,宿主胰岛素抵抗(IR)会降低HCV感染者对干扰素抗病毒干预的应答率,是影响干扰素抗病毒疗效的独立因素;干扰素干预也常出现血糖升高和胰岛素抵抗等临床表现[2 ...

Comparative enhancement of H+ and OH− treatment on electromagnetic interference shielding in aligned and compact Ti3C2Tx MXene film

open access: yesRare Metals, Volume 44, Issue 3, Page 1833-1843, March 2025.
Graphical abstract AbstractThe pressing demand for ultrathin and flexible shields to counter electromagnetic interference (EMI) has sparked interest in Ti3C2Tx MXene materials due to their exceptional electrical conductivity, tunable surface chemistry, and layered structure.
