Shuitu Baochi Xuebao, 2019 通过田间小区磁化水滴灌试验，研究了磁化水膜下滴灌对土壤水盐分布特征、棉花生长特性及产量的影响。结果表明：磁化水灌溉可以提高土壤含水量，促进棉花根系对水分的吸收，0-100 cm土层内磁化强度为3 000 Gs时的土壤含水量最大，保水效果最好。磁化水灌溉可以有效降低土壤盐分含量，加快土壤盐分的淋洗，0-100 cm土层内各磁化水处理土壤平均含盐量表现为3 000 Gs < 4 000 Gs < 1 000 Gs < 5 000 Gs < 0 Gs，磁化淡水处理的土壤脱盐率为2.7%~28.2%，3 000

Rare Metals, Volume 45, Issue 8, August 2026.ABSTRACT Ultrathin, lightweight, and mechanically compliant electromagnetic interference (EMI) shields are increasingly required for high‐frequency electronic devices. However, conventional metallic shields predominantly rely on conductivity‐driven reflection mechanisms, which become ineffective at reduced thickness and may cause severe secondary ...

, 2014 磁雷诺数和流体力学中的雷诺数一样, 是一个无量纲参数。它是用于判断磁通（参见注释1）在磁流体（参见注释2）中是处于冻结还是扩散的一个参数。利用磁通冻结的概念，可以较直观地理解用常规方法产生电磁脉冲的原理。在现代社会中，电磁脉冲有着相当广泛的应用，这里我们通过分析电磁脉冲武器的工作原理，来看看它和磁流体力学中一些相关知识的关系。 以往的经验表明，现代化战争大部分都以电子战的形式拉开序幕。而电磁脉冲武器无疑是电子战武器库中的一个重要成员。在1999年北约轰炸南联盟的战争中，美国第一次使用了电磁脉冲炸弹 ...

Magnetization Dynamics Control for Noise Reduction in Fluxgate Sensors
Rare Metals, Volume 45, Issue 8, August 2026.ABSTRACT Fluxgate sensors are indispensable for the detection of weak magnetic fields. However, their noise performance remains constrained by an incomplete understanding of the interplay between the high‐frequency magnetization dynamics of the core material and the overall sensor behavior.

TbFe層を用いた垂直磁化MTJの熱アシスト磁化反転 [PDF]
, 2011 希土類-遷移金属(RE-TM)膜をメモリー層とした垂直磁化型のTbFe/CoFeB/Al-O/[Co/Pd]_6磁気トンネル接合を作成し,その磁気抵抗(MR)特性および障壁へ印可した電流パルスにより発生するジュール熱を用いた熱アシスト磁化反転を確認した.Al-O層厚0.8 nmのMTJ素子(素子サイズ20μm x 20μm)では低バイアス(40mV)で面積抵抗6 kΩμm^2程度,MR比10%,TbFe層の保磁力4kOe程度が得られた.一方,高バイアス(350 mv)では ...

Flexible, Robust Transparent Conductive Films With Excellent Electromagnetic Shielding Properties
Rare Metals, Volume 45, Issue 8, August 2026.ABSTRACT Transparent conductive films (TCFs) are indispensable components for next‐generation wearable electronics, intelligent robots, and electromagnetic interference (EMI) shielding devices. However, the fabrication of conventional random metallic mesh suffers from an inherent trade‐off between “randomness and controllability”.

Shuitu Baochi Xuebao, 2008 研究了不同侵蚀强度下土壤磁化率及其与土壤化学性质的关系,结果表明:土壤pH、有机质含量和各形态氧化铁含量均与磁化率呈正相关,且氧化铁含量与磁化率呈极显著正相关,表明土壤不同形态氧化铁含量的多少是影响坡面土壤磁化率变化的关键因素。土壤侵蚀导致坡面物质的再分布,从而使土壤pH、有机质、氧化铁含量等土壤化学性质随之发生变化,这些因素随着侵蚀的强弱而发生变化,是影响坡面侵蚀土壤磁性变化的根源。

Rare Metals, Volume 45, Issue 8, August 2026.ABSTRACT The low energy density of sodium‐ion batteries (SIBs) remains a major barrier to their large‐scale deployment. Alloy‐based anodes represent a promising class of materials owing to their high specific capacity and low operating potential for sodium storage. However, their practical application is hindered by severe volume expansion upon cycling.
