摘　　要：从生物体的带电特性出发,对极低频磁场(ELF MF)生物效应的机理从微观上进行了讨论。认为在ELFMF的作用下,生物体的荷电粒子会受到洛仑兹力和力偶矩的作用,导致带电粒子的区域化;同时,ELF MF不仅对生物体自生电流产生力的作用,而且还能在生物体内产生感应生物电流。因此,ELF MF影响了带电粒子的运动和离子的跨膜运转,从而对生物体的多种生理生化特性产生了影响。Based on the fact that biobody contains many particles with electric charge, the mechanisms of biological effects caused by extremely low frequency magnetic field （ELF MF） are discussed in detail. The results show that charged particles of biobody are affected by Lorentz force and torque of couple, and compartmentalized. At the same time, ELF MF not only exerts a Ampere force on endogenous current, but also generates induction electromotive force and induction current in biobody. Therefore, ELF MF has some influence on particle motion, ability of transmembrane transport of ions, and physiological and biochemical characteristics of biobody.
