Analytical Model of Eddy-current Coil Impedance Based on Second Order Vector Potential [PDF]
, 2016 涡流线圈作为电磁换能器的重要组成，在各类电磁无损检测中均有广泛应用。涡流线圈的阻抗解析建模，可以为换能器的设计、及涡流检测的正、逆问题求解提供理论指导与参考。 国内外学者针对该问题的研究主要集中在解析模型的改进与创新、缺陷的反演以及解析模型适用性的扩展，包括被测导电体的特性、涡流线圈与被测导电体的相对位置关系及涡流线圈的类型、参数等。 目前，对任意形状涡流线圈的解析建模工作，主要通过忽略线宽降低求解问题的维度，或对具有一定截面的简单线圈进行叠加，并忽略线圈相互叠加时的细节问题 ...

Fast 3D Gradient Shimming in NMR spectrometers [PDF]
, 2014 核磁共振波谱是物质成分和结构分析的强有力工具。现代许多核磁共振波谱仪采用超导磁体，磁场强度达到10T以上。更为难得的是磁场的均匀度极高，超过10-9，超导磁体的磁场均匀度是远远不够的。有几十组匀场线圈环绕在样品外部，用来产生附加磁场，提高磁场均匀度。如何快速地调节这些匀场线圈的电流，使得核磁共振波谱达到所需的高分辨率，是核磁共振波谱仪技术上的一个难题。一维梯度匀场是现有广泛应用的自动匀场技术。它能够调节部分的匀场线圈。为了能够调节更多的匀场线圈，就需要考虑发展三维梯度匀场技术 ...
