Verification experiment of the direction of the displacement currents by core solenoid [PDF]
, 2013 在实验上直接地验证位移电流的幅值和方向是人们长期以来的奋斗目标。近年来随着测量技术的发展使这种可能性逐步地成为现实。一些学者已经在实验上直接地测量了位移电流的幅值。但目前仅限于位移电流幅值的测量，从未测量过位移电流的方向。本课题组于2010年首先提出在实验中直接测量位移电流的方向的设想，随后提出了几个实验方案并开展了相关的实验研究。 本文采用两种实验方案验证位移电流的方向。分别采用Fammeter传感器（方案一）和单个微晶磁芯传感器（方案二）直接测量在钛酸钡电容器中产生的位移电流方向。在以往的研究中 ...

Preparation of Polyaniline/Polyacrylic Acid（Acrylate）Composites and Investigations of Their Properties [PDF]
, 2005 聚苯胺具有特殊的结构及优异的物理化学性能，可能作为一种新的功能材料在储能、电致变色元件、信息传感、电磁屏蔽、金属防护等方面得到应用。但是聚苯胺，特别是掺杂态聚苯胺的共轭主链呈刚性，且链与链间π-电子体系相互作用较强、极性大、难熔融且难溶于一般溶剂，综合力学性能较差，无法用传统的加工成型方法直接加工成为所需制品；同时掺杂剂本身的不稳定，导致易脱掺杂，使用的温度范围窄，因此极大的限制了它的应用。针对以上问题，本文通过溶液共混的方法，制备出聚苯胺/聚丙烯酸及聚苯胺/聚丙烯酸－丙烯酸丁酯复合材料，通过FTIR ...

Filling Uniformity of AgNPs in EMI Shielding Patch Regulated by Surface Morphology
Rare Metals, Volume 45, Issue 1, January 2026.ABSTRACT Silver nanoparticles (AgNPs) are extensively employed for electromagnetic interference (EMI) shielding owing to their remarkable conductivity, and are commonly incorporated into polymer matrices. Therefore, the uniformity of the AgNP distribution within the polymer matrix is a crucial factor that affects the EMI shielding performance.
