摘　　要：主要利用Matlab软件对磁过滤弯管内和喇叭形管内的磁场分布及强度进行了理论计算,计算结果表明:90°磁过滤弯管内部磁场分布不均匀,中间磁场强,两端磁场弱,在磁过滤弯管出口处磁力线发散;喇叭形内磁场分布也不均匀,也是中间磁场强,两端磁场弱,磁场由上端经过喇叭形的线圈后并不能扩展至整个喇叭形管,磁力线局限于以上端口圆为半径的圆柱体内.Magnetic field distribution in 90° filter solenoid and trumpet-type solenoid were calculated with Matlab. It was found that magnetic filed had non-homogeneous distribution inside the 90°filter solenoid and diverged closing to the nozzle and the magnetic field intensity was strong in the middle of the tube and weak at the tube ends. Magnetic field distribution of trumpet-type solenoid was also not uniform, the magnetic line was confined to a cylinder, the radius of which was the minimum radius of the trumpet-type solenoid, the magnetic field intensity was strong in the middle of the tube and weak at the tube ends.
