摘要：

We model the growth of electrodeposits with diffusion, convection, and migration in an electric field in a rectangular cell. From differential equations, we derive the expressions of growth probability, which predict that the direction and speed of convection and the electric field govern the pattern formation of electrochemical growth. These theoretical predictions are demonstrated by computer simulations. Different patterns, diffusion-limited aggregation, dendritic, dense, needle, and treelike, are governed by two parameters: the convection velocity in the direction parallel to the electrodes, and the flow (convection plus migration in an electric field) perpendicular to the electrodes.
