Rare Metals, Volume 45, Issue 6, June 2026.ABSTRACT Bone restoration is often hindered by the spatiotemporal dysregulation of immune and regenerative signals. Conventional bio‐inert implants, providing only passive support, fail to modulate this microenvironment, leading to infections and poor healing.

Shuitu Baochi Xuebao, 2000 干旱缺水是提高干热河谷旱坡地粮食产量和提高植树造林成活率的主要制约因素。为了充分利用有限的降水，进行了旱坡地“地下地膜隔水墙”节水农业（节水造林）技术及果树节水灌溉栽培试验。结果表明，旱坡地粮食增产6.5%-20.2%，造林成活率提高20%-30％，果树栽培节水率60％－80％，且生长良好。

Structural Modulation of Magnetic Softness in Fe‐Based Amorphous Alloys via Pulse Current Training
Rare Metals, Volume 45, Issue 6, June 2026.ABSTRACT Fe‐based amorphous alloys, despite their intrinsically low magnetocrystalline anisotropy, suffer from quasi‐dislocation dipoles and localized stress fields that impede domain‐wall motion and increase coercivity. Here, we introduce pulse current training (PCT) as an energy‐efficient technique to overcome these limitations in a Fe76Si9B10P5 ...

Shuitu Baochi Xuebao, 2008 以福建闽江上游裸露地为对照,封山育林、杉木和木荷林分为研究对象,分别采用水量平衡法与混合数量化模型对森林水库的调节水总量动态变化及其影响因素进行研究,以期加深对森林水库调水机理的认识。结果表明:木荷、杉木、封山育林林分及对照森林水库2个水文年中调节水总量分别为3 106.27,3 090.41,3 074.05,1 935.29 mm,分别占同期降雨量的97.71%,97.21%,96.70%,60.88%。雨季不同类型森林水库调节水总量均占年内森林水库调节水总量的48%左右,而旱季调节水总量则仅占18%

Si Alloying Enables High Performance in Ce‐Substituted Hot‐Deformed Nd–Fe–B Magnets
Rare Metals, Volume 45, Issue 5, May 2026.ABSTRACT High levels of Ce substitution typically degrade the magnetic performance of hot‐deformed Nd–Fe–B magnets, posing challenges for developing resource‐efficient permanent magnets. Here, we demonstrate that minor Si alloying in (Nd0.6Ce0.4)‐Fe‐B hot‐deformed magnets effectively compensates for this degradation and enables enhanced magnetic ...

Gongye shui chuli, 2016 华北地区某净水厂以当地水库水为水源,原水受到有机物污染,水质受季节影响变化较大。为应对上述水质问题采用高密度沉淀池-V型滤池-超滤-臭氧加活性炭吸附的工艺流程,但该工艺流程较长,运行能耗较高。针对季节和水质变化,以供水安全可靠为前提,高效节能为目标,提出了水厂运行的多线程工艺流程。经节能评估,运行改进后可节能23.96%。
