| 摘 要： | 基于小波变换的分频及时移不变性，将小波变换用于示波计时电位法中重叠峰解析的研究。探讨了极化电流大小、频率和示波信号中噪音、分解次数等因素对小波变换结果的影响。实验结果表明：小波变换能从含有噪音和背景的信号中提取有用信息，使信号中重叠峰获得了较好的分离，可用于多组分的定量分析。

| Abstract: | Based on properties of frequency decom position and tim e shift invariety of w avelet transform , thetransform w as applied in study ofresolving overlapped peaks in oscillographic chronopotentiom etry. Effectof polarized current, frequency, noise in oscillographic signal and decom position frequency on results ofw avelet transform w as investigated. Experim entalresults show ed that w avelet transform is able to recoveruseful inform ation from the osillographic signalw ith noise and background signal. Overlapped peaks in os cillographic chronopotentiom etry is resolved com pletely, w hich can be used in quantitative analysis of m ul ti com ponent. |
