Functional Ecology, Volume 39, Issue 9, Page 2327-2341, September 2025.Read the free Plain Language Summary for this article on the Journal blog. Abstract While elevational patterns of soil bacterial and fungal communities in mountain ecosystems have been well documented, the assembly processes of soil archaeal and protistan communities, and their linkage with ecosystem multifunctionality (EMF), remain poorly understood ...

New Phytologist, Volume 247, Issue 6, Page 2616-2629, September 2025.Summary Seagrasses are important contributors to environmental nutrient cycling in marine ecosystems and can improve water quality by absorbing excess nitrogen (N). However, these ecosystems are vulnerable to human‐mediated pressures, including marine heatwaves (MHWs), particularly those of longer duration. We performed an experiment simulating a 30‐d,

Failure analysis of four tube in power station boiler [PDF]
, 2015 火力发电厂是我国供电主体，约占总体发电量的70%。大型火电厂的安全事关电网的安全运行，而火电厂中的锅炉运行的可靠性是影响发电厂运行可靠性的首要因素，尤其是锅炉四小管的损坏泄漏对机组的安全运行影响最大，是火力发电厂的常见事故，一般占机组故障的60%-70%。锅炉经常由于四小管设计、制造、安装、运行、修理改造、管理等环节的问题以及长期在高温、高压、腐蚀、冲刷等恶劣条件下运行等原因而造成爆管并导致停炉。只有掌握四小管各种类型爆管的失效机理，才能有的放矢开展监督检验工作，寻找有效的管理和技术防治对策 ...

The Research on Wind-induced Vibration Control of Large Span Roof Structures with Different Damping Systems and Optimization of MTMD Damping System [PDF]
, 2016 近年来，随着国内经济实力的增强和社会发展的需要，大跨空间结构在我国得到迅速发展，且跨度越来越大。由于大跨空间结构具有质量轻、阻尼小、柔性大、自振频率低等特点，因而对风荷载的作用很敏感。在风荷载的作用下，结构会产生较大的变形，严重降低结构的安全性和舒适性。为抑制结构的动力响应，学者们提出在结构适当位置处安装控制装置的概念。目前，高层建筑在风荷载作用下的振动控制研究已取得丰硕成果，并有大量的工程应用实例。然而，国内外学者对大跨空间结构的风振控制研究相对较少，因此有必要开展大跨空间结构的风振控制研究 ...
