Passivating electrolyte is taken into account. A mathematical model is presented to illustrate how the machined profile evolves as time elapses. Its numerical analysis and the results of experiment show the actual machining process accords well with mathematical model.

首先建立了反映实际加工过程的数学模型，并考虑非线性电解液的影响，利用参数化有限元分析技术对其蚀除过程进行模拟和数值求解，同时进行了相应的试验验证，试验结果显示，模拟蚀除的深度和直径与实际加工的深度和直径相符。

During the infiltration process of indirect subsurface drip irrigation, the ponded water depth changed from zero to a constant and accelerated the water movement in the vertical direction, which reduced the discrepancy of wetted distance in lateral direction and vertical direction, while the changed water depth had small influence on the wetting front movement in vertical direction to upward and downward. The shape of wetted soil zone was spheroid, and its symmetry axis lied near the bottom of the water conducting device.

间接地下滴灌灌水过程中，从零开始逐渐增大并趋于稳定的积水深度加速了水分在垂直方向的运移，缩小了横向湿润距离和垂向湿润距离之间的差异，但变化的积水深度对湿润锋在垂直方向向上和向下的运移速率影响不大，使湿润体形状表现为扁率不断减小的椭球体，且椭球体对称轴分布在靠近导水装置底部的位置。

The results indicated that the optimum depth of ponding water was 9cm, and the optimum water management regime was variable irrigation.
