The calculating values and space graphics of magnetic vector potential, magnetic induction, magnetic energy density were gained with the finite element method. Magnetic force lines and magnetic induction equivalence lines were drawn also. 采用有限元数值法计算得出圆片磁源空间磁场的矢量磁位、磁感强度、磁场能量密度量值和空间分布图,并计算绘出磁力线和磁感强度等值线。

They are derived by use of the ratio of the macroscopic kinetic energy density to the magnetic energy density. 它们是利用宏观动能密度对磁能密度的比例导出的。
With these magnetic fields, the plasma is converged above the sample holder and the permanent magnet unit, and the energy density of plasma is enhanced obviously. 这一磁场可使等离子体集聚于样片台上方,显著提高了等离子体的能量密度。
Furthermore, the magnetic field cannot change the total energy density distribution of ions, but the Lorentz force does influence its movement state, and at the same time affects the ion energy distribution in every directions, as well as the incidence departure angle of ions. 此外,虽然磁场不能改变离子总的能量密度分布,却能改变离子的运动状态,并同时影响着基板上离子在各个方向上的能量分布和入射偏移角度。
The ratios of the magnetic to the thermal pressure and to the kinetic energy density increase significantly within the transient streams generated by the bright flares, and decrease within those generated by the non-bright ones. 亮耀斑与非亮耀斑瞬交流的主要差别是前者的磁压力相对于热压力和动能密度的比值均明显地增高,而后者则反比背景值有所降低。
Cavity resonance loss, dielectric or resistance loss, and magnetic loss are the main pathway to convert electromagnetic wave into other energy forms for dissipation. Existent absorbing materials still have disadvantages such as high density, large thickness, low absorption and narrow bandwidth. 空腔共振损耗、介电或电阻损耗、磁损耗是将电磁波吸收转化为其他形式能耗散的主要机制,现有电磁波吸收材料需要克服密度高、厚度大、吸收少和频带窄的缺点。
