Veterinary Dermatology, Volume 34, Issue 5, Page 393-403, October 2023., 2023 Background – Grass leaf has been suspected to cause immunoglobulin (Ig)E‐mediated immediate hypersensitivity reactions both in humans and in dogs. However, most studies in this area are case control studies without in vitro data showing the involvement of IgE in the reaction.

Dianci bileiqi, 2020 变压器绝缘套管中实际加载的电压波形中谐波成分含量较高,为了探究电压谐波对变压器套管电容芯子介质损耗的影响,基于频域有限元法建立了220 k V电容式变压器套管的有限元模型,获得了变压器套管电容芯子绝缘介质的非线性频变特性曲线,并进一步考虑了电容芯子介电常数频变特性对其介质损耗发热的影响。在给定波形参数下,电容芯子在谐波作用下的频变特性对介质损耗发热的增强系数仅为0. 27%,高次谐波对电容芯子的介质损耗发热影响较小。研究结果对于电容式套管的介质损耗发热和其事故分析具有一定的参考价值。

Simulation and Analysis of the Dynamic Range of the Lunar Radar and A New Algorithm for Surface Medium Electromagnetic Parameters Inversion [PDF]
, 2016 探地雷达(GPR)通过向地下发射高频率宽带电磁波来探测地下物体、地层界面以及地下介质属性和分布结构，被广泛应用于经济建设和军事各领域。由于雷达信号会受到各种电磁和背景噪声干扰，使得接收到的信号不能直接准确地反映地下介质信息，造成对目标检测和识别的困难。特别当处于非理想环境条件下，非目标介质反射信号干扰复杂，目标的反射波很难被识别。在对路面、隧道以及地下等检测时，遇到的地下介质多是层状分布的。人们不仅希望获得各层的深度和厚度，还希望得到各层介质的介电常数和电导率等参数。因此，本文将地表层介质作为研究的对象，
