The dynamics of brdging transfer are theoreticall and experinmentally investigated. Time-dependent deformation of the liquid bridge, which is formed between the electrode and the pool by a contact of a pendent drop with the pool surface, is obserbed by high speed photography and simulated with aids of the numerial solution technique for the dynamics of a biscous incompressible fluid with a free surface (MAC method) based on Finite-Difference Method. It is shown that the liquid of the pendent drop is driven to flow into the pool by the capillary force and the electromagnetic pinch force acting on the conducting bridge.

BRDGIN转移的动力学是理论上的，并在实验研究中进行了研究。液体桥的时间依赖性变形是通过高速摄影观察到的，通过吊坠与泳池表面的接触在电极和池之间形成，并用数字溶液技术的辅助图模拟，以便用于动力学的动力学。基于有限差分法的饼干不可压缩的液体（MAC方法）。结果表明，垂直滴的液体被毛细管力和作用在导电桥上的电磁捏力流入池中。
