实现了坐标变换，极大地方便了描述瞬态离子扩散和迁移到圆盘电极的方程的数值解。变换后的坐标是经典扁球坐标的修正形式；去除电极边缘产生的奇异点，将无限模型空间压缩为有限矩形。由此节省的存储和执行时间使得以前困难且计算代价昂贵的数值计算成为可能
A coordinate transformation is implemented that greatly facilitates the numerical solution of the equations describing transient ionic diffusion and migration to a disk electrode. The transformed coordinates are a modified form of the classical oblate spheroidal coordinates; singularities arising at the electrode edge are removed, and the infinite model space is collapsed down to a finite rectangle. The resulting savings in storage and execution time make it feasible to do numerical calculations that were previously difficult and computationally expensive
