地震波动谱元法数值模拟研究进展

Dizhen xuebao
基于谱元法的地震波动数值模拟已被广泛用于地震震源破裂、大规模地震波传播、区域复杂场地及工程结构（群）地震反应、地震层析成像等重要问题的研究及应用当中，是目前地震工程学、地震学和地球物理学等地震科技领域共同关注的前沿热点技术。早期发展的切比雪夫谱元法（CSEM）和勒让德谱元法（LSEM）更接近谱方法的域分解思路，其形式相对复杂且计算效率较低。目前广泛使用的是一种形式简洁的LSEM，其实施步骤和主要公式已经与有限元法完全一致，仅通过内置的高斯-洛巴托-勒让德（GLL）高精度数值积分保留着与谱方法之间的联系 ...

Evaluating the use of taxonomy in the IUCN Red List

Conservation Biology, EarlyView.
Abstract Taxonomy defines the units that conservationists strive to preserve for future generations. However, the discovery of new species and the taxonomic revision of existing species affect conservation efforts. Despite the importance of taxonomy for a species’ conservation, there is currently no overview of how those leading species extinction risk

Super‐High Coercivity Sintered NdFeB Magnets Enabled by High‐Rate Dy/Tb Grain Boundary Synergistic Diffusion

Rare Metals, Volume 45, Issue 6, June 2026.
ABSTRACT The surging demand for high‐performance NdFeB magnets has made it essential to achieve ultrahigh coercivity while minimizing the consumption of heavy rare earths. To tackle this challenge, this study proposes a Dy/Tb bilayer grain boundary diffusion strategy and systematically investigates the co‐diffusion behavior of Dy and Tb.

The numerical investigation of non-Newtonian fluid filling process via finite element and discontinuous Galerkin method(三维非牛顿流体充填过程的有限元-间断有限元数值模拟研究)

Zhejiang Daxue xuebao. Lixue ban, 2023
针对三维非牛顿流体充填问题，建立了有限元-间断有限元耦合算法。对于两相Navier-Stokes方程，基于压力增量修正格式分三步求解，分别采用二次和一次拉格朗日插值多项式求解速度和压力，以确保计算过程稳定。采用守恒型水平集（level set）方法追踪运动界面，并依据间断有限元方法求解水平集和重新初始化方程。以三维圆球剪切流动及非牛顿流体三维平板型腔充填过程为例，并与已有文献的数值和实验结果进行比较，以验证数值算法的稳定性、准确性以及流体的质量守恒性。

Ultralight N‐Doped Interconnected Porous Carbon From Lignin: Synergistic Structural and Doping Engineering for High‐Performance Electromagnetic Wave Absorption

Rare Metals, Volume 45, Issue 6, June 2026.
ABSTRACT The development of lightweight, high‐attenuation, and broadband carbon‐based electromagnetic wave absorbers is hindered by the intrinsic trade‐off between impedance matching and dielectric dissipation. Herein, we report a facile and scalable synthesis of N‐doped lignin‐derived interconnected porous carbon (Nx‐LIPC) via hydrogen‐bond self ...

Structural Modulation of Magnetic Softness in Fe‐Based Amorphous Alloys via Pulse Current Training

Rare Metals, Volume 45, Issue 6, June 2026.
ABSTRACT Fe‐based amorphous alloys, despite their intrinsically low magnetocrystalline anisotropy, suffer from quasi‐dislocation dipoles and localized stress fields that impede domain‐wall motion and increase coercivity. Here, we introduce pulse current training (PCT) as an energy‐efficient technique to overcome these limitations in a Fe76Si9B10P5 ...

电力机车主变压器油箱损耗的三维有限元分析

Gaoya dianqi, 2005
利用基于边单元的有限元法,对一台200km/h高速电力机车主变压器的油箱损耗进行了三维有限元分析和计算。由于电力机车主变压器是高漏抗,多绕组变压器,经试验（采用放大法）得到该台变压器油箱损耗为31.245kW,使用FEM二维有限元分析法计算结果为45.791kW,而采用三维有限元分析法计算结果为30.478kW。从而表明,采用三维有限元分析能够更加准确地计算主变压器油箱的涡流分布和杂散损耗,为其采取有效的屏蔽措施提供了更加可靠的科学依据。
