【摘要】 通过用计算机控制的PCI-1710HG数据采集卡记录和用Matlab分析程序处理电流时间序列,使用恒电位方法研究磷酸中铜阳极电溶解过程的复杂电流振荡。结果表明,在电溶解过程中存在确定性的电流混沌。在利用时间序列重构三维相空间吸引子时,提出了一种确定最优延迟时间的可操作的定量方法。更多还原

【Abstract】 The complex current oscillation of the copper anodic dissolution in phosphoric acid is investigated with potentiostatical method by using the electrochemical apparatus connected with a Pentium computer with PCI-1710HG card and Matlab nonlinear analysis program for record and disposal of the complex current time-series. The results show that the determinative current chaos exist during the electrodissolution.An operational quantitative method is put forward and used to determine the optimal delay time when 3-dimension phase space attractor of the timeseries is reconstructed.更多还原
