摘要
本文通过生物细胞模型,研究振荡电场、振荡磁场以及振荡磁场产生的感应电场对细胞离子的作用机理。模型分析结果表明,电场力和罗仑兹力对细胞膜两侧的自由离子将产生加速度,振荡离子将产生周期性电位移。该模型同时也解释了脉冲电磁场比同参教的连续场产生更多的生物效应,以及连续场在开始施加和切除时的效应最大。
This paper presents a biological cell model to analyze the action of oscillating electric field, oscillating magnetic field（OMF） and the induction field induced by OMF on cells. The analysis of model shows that electric force and Lorentz force accelerate the free ions on both sides of all plasma membranes. And the oscillating ions will move in periodic displacement. The model also explains why pulsed electromagnetic fields can produce more biological effects than continuous fields of the same characteristics, or why the greatest effects of a continuous field may occur with onset or removal of exposure.
