摘　　要：为了得到磁开关磁芯在磁压缩电路中的磁参数，仿照不需要附加磁芯复位电路的单级磁脉冲压缩电路，设计并搭建了试验系统，对Mn—Zn铁氧体磁芯进行了测试。分析了测试原理和计算方法，通过测试和运算得到了磁芯的磁滞回线，进而得到了在快脉冲激励情况下该磁芯的饱和磁感应强度，剩磁，矫顽力等参数。A testing system was designed based on the one-stage magnetic pulse compression circuit which does not contain external demagnetization circuits, and a Mn-Zn ferrite core was tested to get its magnetic properties in the magnetic compression system. Through the test and computing, the magnetic hysteresis loop was obtained, and the saturation induction density, residual magnetism destiny and coercive force was acquired.
