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.

对桥接传递动力学进行了理论和实验研究。利用高速摄影技术，利用基于有限差分法的自由表面双相不可压缩流体动力学数值求解技术，对电极与池之间由于悬垂液滴与池表面接触而形成的液桥的随时间变形进行了观测和模拟。结果表明，在毛细管力和电磁力的作用下，悬垂液滴中的液体被驱动流入池中。
