研究了在垂直非均匀强磁场（高达15 T）中Ag+/Cu液-固氧化还原反应。通过对不同磁场强度下生成的准三维银枝晶形貌的比较，发现强磁场对银枝晶的聚集过程有很大的影响。本实验采用四种受反应方向和溶液条件影响的液固界面作为银沉积的扩散限制聚集（DLA）状枝晶生长的基础。结果被解释在对流的水溶液和一个试探性的定量分析所产生的磁场作用在颗粒上的力量。理论上预测了一种新的力，并进行了详细的讨论。
The Ag+/Cu liquid–solid redox reaction was investigated in a vertical and inhomogeneous high magnetic field (up to 15 T). According to a comparison between the morphologies of quasi-3D silver dendrites generated under different magnetic flux densities, the imposition of a high magnetic field strongly affected the aggregation process of the silver dendrites. The present experiment used four kinds of liquid–solid boundaries, which are affected by the reaction direction and solution condition, as bases for the diffusion limited aggregation (DLA)-like dendritic growth of silver deposition. Results are interpreted in terms of convections of the aqueous solution and a tentative quantitative analysis of forces acting on particles arising from the magnetic field. A new force is predicted theoretically and is discussed in detail.
