摘要
研制了一种强度、频率及信号占空系数均可调节的生物医学研究用低频方波电压调制四阶均匀交变磁场 .并提出激发场生物效应的不可忽略性 。
In this paper, we have designed and prepared the low frequency square wave voltage modulating fourth order uniform alternating magnetic field. The magnetic induction dencity, the frequency and the signal duty factor of the field can be regulated. In addition, we advance: (1) the biological effects of the excited field must not be neglected; (2) the reason of resulting in the differeces in biomedical action between unstable and stable magnetic field.
