摘要： 提出了一种强脉冲刺激器的设计方案,应用此方案设计了一台基于心脏刺激的强脉冲磁场刺激装置.该装置的充电电压达到1200V时,在刺激线圈中心可以获得磁感应强度为10.6 T的磁场.阐述了该磁场刺激装置的具体设计思想和磁感应强度的计算方法.应用刺激线圈中心磁感应强度为2.7 T,周期为0.2Hz的脉冲磁场刺激开胸蛙的心脏,结论是脉冲磁场直接刺激蛙的心脏可以改变蛙的心率.

Abstract: A strong pulsed magnetic field stimulator was designed successfully and made for cardiomuscle to study the biomagnetic effect on heart. An electromagnetic field with magnetic induction up to 10.6 Tesla can be obtained at the center of its exciting coil when the DC charging voltage is 1200 V. The method to calculate the induction is given. An open chest frog was stimulated by the pulsed magnetic field with magnetic induction 2.7 T at 0.2 Hz, and the result showed that its heart rate is restored after a fluctuation caused by the stimulator.
