摘要

研究了均匀和静态中等磁场（0–400mT）对Metapenaeus ensis虾神经纤维膜电位的影响。结果表明，磁场导致膜电位增加，最终达到静态，短期暴露的影响在很大程度上是可逆的。观察到膜电位（V%）的百分比变化和磁场感应之间的非线性关系，其中V%在拐点（约200mT）以下快速增加，此后减慢。假设表明，膜中的离子通道对磁场具有不同的敏感性，并呈现出离子通道激活阈值在0–400 mT范围内的分布。拐点的识别在磁场治疗、暴露极限和磁屏蔽设计等领域具有重要的实用价值。

Effect of Moderate Static Magnetic Field on Membrane Potential of Abdominal Nerve Fiber in Metapenaeus Ensis

The effects of uniform and static moderate magnetic fields (0–400 mT) on the membrane potential of nerve fibers in Metapenaeus ensis shrimps were investigated. The results showed that the magnetic field caused an increase in membrane potential, eventually reaching a static state, and that effects of short-term exposure were largely reversible. A nonlinear relationship between the percentage change in membrane potential ( V% ) and magnetic field induction was observed, where V% increased rapidly below an inflection point (around 200 mT) and slowed down thereafter. Hypotheses suggest that ion channels in the membrane have varying sensitivities to magnetic fields and presented the distribution of ion channel activation thresholds within the 0–400 mT range. The identification of the inflection point holds great practical value in the fields of magnetic field therapy, exposure limits, and magnetic shielding design.
