建立了磁场电化学光整加工中离子运动轨迹方程，通过实验分析了磁场对光整加工的作用及整平机制． 研究结果表明： １）磁场活跃了离子运动轨迹，改变了离子到达试件表面的方式，从而改善了表面粗糙度； ２）磁场的搅拌作用，加强了液相对流、离子的扩散和迁移，改变了电化学反应，使极间电流强度增大，加工效率提高； ３）磁场、电场和电极间隙存在最佳匹配关系．
The equations of ion trajectory in the magnetic field electroforming process are established. The effect of magnetic field on the finishing process and the leveling mechanism are analyzed experimentally. The results show that: 1) the magnetic field activates the trajectories of ions and changes the way ions reach the surface of the specimen, thus improving the surface roughness; 2) the agitation of the magnetic field strengthens the liquid convection, the diffusion and migration of ions, The electrochemical reaction increases the interelectrode current intensity and improves the processing efficiency. 3) There is the best match between the magnetic field, the electric field and the electrode gap.
