低频 电磁场数值 低频涡流场 有限元编程
2023/4/13
本报告首先回顾传统低频涡流场的两种计算格式，指出有限元编程实现过程中的基函数选择以及需要注意的难点问题。第二部分针对静磁场问题，通过引入规范条件提出了一种基于矢量磁位和磁场强度的新型的对偶格式，该方法通过巧妙构造基于矢量磁位和磁场强度的计算格式，整体矩阵完全一致并且可以给出系统电感参数的上下界，在实际参数提取中有很好的应用前景。在第三部分，由于传统低频涡流场近似不能有效考虑分布电容效应，而传统高频...

LOW-FREQUENCY ELECTRIC FIELDS INDUCED SPHERICAL CELL NUCLEUS
2015/10/16
After a review of work leading to the determination of the electric field induced in the human body when exposed to the electromagnetic field near an extremely-low-frequency high-voltage transmission ...
K-L->pi(0)gamma e(+)e(-) and its relation to CP and chiral tests
Decay in Kuala Lumpur non radiation chiral perturbation theory the quantitative easing policy
2014/12/22
The decay KL→π0γe+e- occurs at a higher rate than the nonradiative process KL→π0e+e-, and hence can be a background to CP violation studies using the latter reaction. It also has interest in its own r...
Scanning Superfluid-Turbulence Cascade by its Low-Temperature Cutoff
Kolmogorov low temperature quantization the vortex line density coefficient of friction
2014/12/19
On the basis of a recently proposed scenario of the transformation of the Kolmogorov cascade into the Kelvin-wave cascade, we develop a theory of low-temperature cutoff. The theory predicts a specific...
