MR 3D-VIBE序列多期动态增强扫描在原发性肝细胞癌中的应用
Zhongshan Daxue xuebao. Yixue kexue ban, 2017 【目的】通过对原发性肝细胞癌（HCC）的MR三维容积插入屏气检查（3D-VIBE）多期动态增强扫描与多层螺旋 CT（MSCT）增强扫描的对照研究，探讨MR 3D-VIBE序列动态增强扫描在显示HCC的动态强化特点中的价值。【方法】收集 23例在我院行上腹部3.0T MR 3D-VIBE多期动态增强扫描及MSCT双期增强扫描的HCC的患者的临床及影像学资料，对比 3D-VIBE序列动态增强扫描及MSCT增强扫描显示肿瘤的强化特点。【结果】23例经手术证实共发现23个HCC，MRI 3D ...

Gaoya dianqi由于柔性直流输配电系统发生故障时电流上升快、破坏性强，亟需快速稳定的直流断路器。文中提出一种基于半硬磁材料的操动—保持一体化机构，兼具电磁激励快速响应与高保持力特性。首先利用Jiles-Atherton结合粒子群算法分析了半硬磁材料的磁滞特性，并建立了半硬磁机构的等效磁路，分析机构电磁力的影响因素。然后，基于Comsol多物理场有限元仿真软件建立了半硬磁机构的仿真模型，分析了半硬磁机构的静态过程与动态过程，得到了过程中的电磁特性与机械特性。最后，根据仿真结果搭建了半硬磁机构样机，进行半硬磁机构动作实验 ...
