We seek to extend the recent suggestion that classical cyclotron resonance of biologically important ions is implicated in weak electromagnetic field-cell interactions. The motion of charged particles in a constant magnetic field and periodic electric field is examined under the simplifying assumption of no damping. Each of the nine terms of the relative dielectric tensor is found to have a dependence on functions that include the factor (omega 2 - omega 2B)-1, where omega B is the gyrofrequency. We also find a plasmalike decomposition of the electric field into oppositely rotating components that could conceivably act to drive oppositely charged ions in the same direction through helical membrane channels. For weak low-frequency magnetic fields, an additional feature arises, namely, periodic reinforcement of the resonance condition with intervals of the order of tens of msec for biological ions such as Li+, Na+, and K+.
我们试图扩展最近的一项观点,即具有生物学重要意义的离子的经典回旋共振与弱电磁场-细胞相互作用有关。在无阻尼的简化假设下,研究了带电粒子在恒定磁场和周期性电场中的运动。发现相对介电张量的九个项中的每一项都依赖于包含因子(ω² - ωB²)-1的函数,其中ωB是回旋频率。我们还发现电场类似等离子体地分解为反向旋转的分量,这可以想象会促使带相反电荷的离子通过螺旋膜通道沿相同方向运动。对于弱低频磁场,还出现了一个额外的特征,即对于诸如Li⁺、Na⁺和K⁺等生物离子,共振条件以几十毫秒的间隔进行周期性增强。
