Factors influencing fine roots decomposition rates in response to nitrogen addition vary across root characteristics

open access: yesFunctional Ecology, Volume 39, Issue 12, Page 3504-3516, December 2025.
Read the free Plain Language Summary for this article on the Journal blog. Abstract Nitrogen (N) deposition strongly affects litter decomposition and nutrient release, thereby reshaping carbon cycling in terrestrial ecosystems. Although most studies have focused on above‐ground litter, the effects of N addition on fine root decomposition and their ...

网壳结构“折叠展开式”计算机同步控制整体提升施工技术

open access: yesJianzhu Gangjiegou Jinzhan, 2005
网壳结构“折叠展开式”计算机同步控制整体提升施工技术是一种新型的、技术先进的大跨度网壳结构的施工方法。它的基本思想是将网壳结构局部抽掉少量杆件,将结构分成若干区域,并设置一定数量的可动铰节点,使结构变成一个机构。在靠近地面拼装,然后采用液压提升设备,通过计算机同步控制,将结构提升到设计高度,再补充缺省杆件,使机构变成稳定的结构状态。这种方法可以节省大量脚手架,避免高空作业,保证施工人员的安全,适合矢跨比比较大的网壳结构,具有明显的经济效益和社会效益。网壳结构“折叠展开式 ...

射频碳氟等离子提升环氧树脂沿面耐电性能的研究

open access: yesGaoya dianqi, 2023
在绝缘系统中复合界面的沿面耐电强度远低于固体、气体或真空侧的击穿场强,这严重限制了电力设备的整体绝缘性能。表面氟化被证明是提升绝缘材料沿面耐电性能的有效手段,其中利用碳氟等离子体对绝缘材料进行表面氟化展现出独特的优势。文中采用CF4射频电容耦合等离子体(capacitively coupled plasma,CCP)对环氧树脂进行表面改性以提升其表面绝缘性能。利用单反相机和光谱仪诊断CCP的放电模式和活性粒子,建立一维流体仿真模型对其电子能量和密度进行分析。通过原子力显微镜、X射线光电子能谱仪 ...

Universal cervical‐length screening to prevent preterm birth in twin pregnancy: cost‐utility analysis

open access: yesUltrasound in Obstetrics &Gynecology, Volume 66, Issue 3, Page 290-297, September 2025.
ABSTRACT Objective The purpose of this cost‐utility analysis was to model the clinical and economic impact of three cervical‐length screening strategies among low‐risk twin pregnancies: two‐step universal screening (at 18–20 and 20–22 weeks), one‐step universal screening (at 18–20 weeks) and no screening.

基于热电耦合方法的800 kV GIS隔离开关温度场仿真研究

open access: yesGaoya dianqi, 2020
温升是GIS设备的重要考核指标之一,温升过高会导致设备发热严重,进而影响GIS运行的可靠性。为准确分析GIS的发热和温升,基于有限元分析软件,通过热电耦合方法,建立800 kV GIS隔离开关损耗发热的求解模型,在综合考虑导体及外壳不同的散热系数、环境温度和材料电阻率随温度变化等多种因素的基础上,计算分析隔离开关的整体温度场分布。通过温升试验,对比主要部位温升的计算值和试验值,证明了该方法的准确性,为隔离开关的设计提供了参考。
