Journal of Ecology, Volume 114, Issue 8, August 2026.Ectomycorrhizal roots of Pinus armandii release more carboxylates than non‐mycorrhizal root segments, mobilizing Al‐bound inorganic P. Under the lowest available P conditions, they also secrete more phosphatase, promoting the mineralization of Al‐bound organic P.

Rare Metals, Volume 45, Issue 7, July 2026.ABSTRACT In electrocatalysis, traditional single‐atom catalysts (SACs) face challenges in achieving coordinated control of reaction pathways due to limitations such as single local energy levels and carrier recombination. By introducing an additional defect structure, it is possible to break the electronic structure symmetry, thereby activating SACs ...

Gongye shui chuli, 2007 高铁酸钾是一种新型高效的多功能水处理剂,而垃圾渗滤液中氨氮浓度过高会降低生化处理中微生物的活性,需要进行前处理去除一部分氨氮。作者通过模拟实验得出用高铁酸钾去除废水中氨氮,在 m (高铁酸钾):m (氨氮)=4:1,pH 为9时,处理效果最佳,而处理效果受温度影响不大。高铁酸钾对垃圾渗滤液中氨氮去除率可达 60% 。

Dianci bileiqi, 2021 复合绝缘子在输电线路中发挥着支撑导线和防止电流回地的作用。随着我国高速铁路的快速发展,许多跨越高铁输电线路的复合绝缘子在列车风的影响下出现了伞裙的撕裂情况。本研究通过复合绝缘子伞裙特征,研究了绝缘子伞裙固有频率、伞径、伞倾角等因素对抗高铁运行带来的风能的影响,并以此为依据,提出了跨高铁输电线路复合绝缘子的选取方法,所得结果可为跨高铁输电线路抗风型复合绝缘子的设计和选型提供参考。

Gaoya dianqi, 2017 雷害是影响高速铁路安全稳定运行的关键因素之一,研究雷电先导作用下高速铁路周围电场的变化规律对于高速铁路雷击机理的阐明具有重要意义。文中结合先导法建立了高速铁路三维雷击仿真模型;通过调整导体携带电荷量、高度及侧面距离,来模拟不同雷电流幅值以及先导空间位置对高速铁路周围电场分布的影响;并对比分析了高架区段和路基区段高速铁路周围场强分布情况。研究发现,在雷电流幅值为数千安时,高速铁路周围仍有上行先导产生,因此认为在雷击计算中,雷电流较小情况仍需考虑上行先导;随着雷电流幅值、下行先导空间位置的变化 ...

Dianci bileiqi, 1993 超导磁铁系统最早应用于诸如加速器和核装置等特殊领域。近几年高温超导体已逐步扩展到工业应用。美国化学工程进展杂志报道超导除铁器用于高白高纯高岭土的处理,这在世界上属首次。以往的除铁处理方法是,使高岭土泥浆通过磁室-φ 2.1m高0.5m的大型容器,在2T的磁场作用下,能清除2μm以下的顺磁杂质。磁铁乃是绕有水冷线圈的螺线管。装置的功率为270～600kw。将这种磁铁换用超导磁铁后,尽管所用的液氮和液氦冷却系统很复杂 ...
