摘　　要：给出了电化学加工极间间隙的计算公式,介绍了双电层电容结构及性质,在分析高频窄脉冲电化学加工为暂态加工的基础上,提出了基于电容的高频窄脉冲电化学加工数学模型,讨论了脉冲频率、占空比对阳极蚀除速度的影响,并对脉冲频率、占空比、初始间隙与阳极蚀除速度及极间间隙的变化关系进行了模拟和仿真。The formula of inter-electrode gap in high frequency pulse electrochemical machining （ECM） is introduced, the structure and characteristics of double layer capacity are describled. The pa~ per also presents the mathematical model based on capacity model of high frequency pulse ECM after analysis the processing as transient electrode process, and discusses the influence of the frequency and dutycycle of pulse to the dissolved speed of anode. In addition, the verification experiments are made to certificate the contacts between frequency,dutycycle,initial gap and the inter-electrode gap.
