Changing electromagnetic fields affect living organisms but the mechanisms of these effects are unknown. This proposal is to examine the hypothesis that the fields change the rate of calcium diffusion through the cell membranes by a mechanism involving cyclotron resonance. The approach will be to investigate the transport of calcium ions across artificial membranes with different characteristics, such as porosities and surface charges. The effects of the direction of the field on the transport will be also examined. This work may provide important insight into the mechanisms by which electromagnetic fields affect ion transport. Knowledge of these mechanisms would have applications in both medicine (electrically induced tissue healing, for example) and industry (such as separation technology).

变化的电磁场影响生物体，但这些影响的机制尚不清楚。这一建议是检验假设，即场改变钙的扩散速率通过细胞膜的机制涉及回旋共振。该方法将研究钙离子在具有不同特性（如孔隙率和表面电荷）的人工膜上的运输。还将研究电场方向对输运的影响。这项工作可能为了解电磁场影响离子输运的机制提供重要的见解。这些机制的知识将在医学（例如电诱导组织愈合）和工业（例如分离技术）中都有应用。
