工频电磁场生理危害的研究进展

许多流行病学调查和实验室研究提示了工频电磁场（PFEMF）暴露与白血病、肿瘤、胚胞异常等发病率上升存在相关性，但同时也有相当的实验未观察到PFEMF的效应．在理论上分析了微弱电磁场作用机制的争议，并根据非线性分又理论分析，肯定了PFEMF的潜在危害，进一步指出这种危害是一种随机现象．回顾了近年来提出的PFEMF危害机制和模型，认为研究应结合各种非线性理论．

A review on the study on power frequency electromagnetic field hazards to organisms

On the power frequency electromagnetic field (PFEMF) bioeffects on organisms, there have been much epidemiological survey and laboratory study which confirm the relation of leukemia, tumor and embryo abnormality with PFEMF exposure; but at same time, there are also a few reports on the opposite side. After the controversy of weak electromagnetic field bioeffect mechanism was analyzed in ideology based on the nonlinear divergence theory, and the models and mechanisms of hazards proposed in recent year were reviewed, the potential hazards of PFEMF to organisms were affirmed; moreever, the hazards were random events and should be studied with various nonlinear theories.
