　　Abstract　An experimental device, low frequency magnetic fields pulse generator, has been designed and accomplished in our department. It can provide low frequency magnetic fields pulse with the intensity from 150mT to 800mT and the frequency from 0 to 100Hz. This device is easy to operate and performs reliably. It can stably work for a long time and has been successful used in the experiment of magnetic biological effect.

　　随着现代科技的迅猛发展，人类所处的生存环境被越来越复杂的电磁场所充斥，对电磁场生物效应的研究已日益受到重视，而低频场的非热效应一直是该领域的研究重点^［1，2］。本教研室对低频脉冲场生物效应的研究已进行多年，积累了丰富经验，研制出可产生强度变化范围0.1～2 T的低频强脉冲磁场发生器^［3］，但该仪器频率极低，很难满足连续辐照的实验要求，为了对低频脉冲磁场不同频率及强度长时间辐照的生物效应进行研究，我们研制了CXLY-Ⅱ型脉冲磁场发生仪，该仪器可产生频率0～100 Hz，磁场强度150～800 mT连续可调的脉冲磁场，可长时间工作，磁场作用区(85 mm×40 mm×25 mm)可放入小鼠、细胞培养板、细菌培养皿等多种体积形状的物体，可用于研究磁场对动物、细胞、细菌等多种生物体作用的效应。
