从动力学(Vlasov方程)而不是流体动力学的角度考虑了热各向同性等离子体中短丝天线的输入阻抗。并对两种方法的结果进行了比较。结果表明，除了低于等离子体频率的频率外，动态法给出的阻力横向分量与流体动力学法得到的阻力横向分量非常接近。在这两种方法中，电阻的纵向分量只有在比等离子体频率大的频率下才一致。
The input resistance of a short filamental antenna in a warm isotropic plasma is considered from the kinetic (Vlasov equation) rather than the hydrodynamic approach. The results of the two approaches are compared. It is shown that the transverse component of the resistance given by the kinetic approach agrees closely with that of the hydrodynamic approach except for frequencies below the plasma frequency. The longitudinal component of resistance agrees in the two approaches only at frequencies which are large compared with the plasma frequency.
