Gongye shui chuli, 2011 以硫酸亚铁和硫酸镁为粉煤灰改性剂,通过聚合反应制备了铁镁复合改性粉煤灰,研究了原料配比对改性粉煤灰脱色性能的影响。用改性粉煤灰对模拟印染废水和实际印染废水进行了脱色处理,结果表明,脱色过程中絮体生成快、大而密实、易于泥水分离,模拟印染废水和实际印染废水的脱色率均大于90%。

Rare Metals, Volume 45, Issue 4, April 2026.ABSTRACT The inherent trade‐off between high saturation induction (Bs) and low core loss in soft magnetic materials presents a challenge in the development of high‐frequency power electronics. Here, a processing approach that combines accelerated Cu ordering with dual magnetic anisotropy control in high‐Bs Fe‐based nanostructured cores is examined ...

Rare Metals, Volume 45, Issue 3, March 2026.ABSTRACT Reliable operation of high‐performance magnetostrictive devices, composed of the giant magnetostrictive material (GMM), that is, the TbDyFe alloy, critically depends on an optimally tailored bias magnetic field. Sufficient intensity and uniformity are essential to induce the ideal initial strain in the GMM, enabling peak reciprocating output ...

Zhongguo shiyan zhenduanxue, 2006 目的探讨缺铁性贫血与促红细胞生成素的关系。方法采用EPO测定法,血浆EPO浓度的测定运用了ELISA测定法,用Blotkalbumin取代血液BSA进行非特异性蛋白结合部分的实验,并采用了YHA、EPO、EPOGIN标准,在进行老鼠血浆浓度测定时,YHA———EPO标准的运用的稳妥性的认证。结论通过实验分析由缺铁性贫血而导致血液中携氧能力的下降,会使血浆中EPO浓度增加,促进红细胞的生成。此外,在铁缺乏的状态下,特久训练会促成EPO的生成。然而,对于机能增加而相关联的携氧能力的改善 ...

Shuitu Baochi Xuebao, 2011 通过分析添加含铁材料(Fe2O3、Fe2(SO4)3)和稀土材料(CeCl3、LaCl3)后矿区污染土壤中交换态砷(As)含量和土壤pH值的变化规律,研究这2类材料对矿区土壤As的固定效果以及对土壤性质的影响。结果表明,Fe2O3对As固定效果不明显,当Fe2O3最大添加量为8g/kg(分别按Fe计)时,土壤中交换态As含量仅降低了3.81%,其他3种材料在本试验条件下表现出良好的效果,其中Fe2(SO4)3和LaCl3固定As的效果相当,CeCl3次之。当这3种材料的添加量分别为2,4,8g/kg ...
