| 摘 要： | 目的：探索中医脉诊客观化的新方法。方法：根据小波变换过零点和信号突变点之间的关系，分别运用小渡变换过零点表征检测脉象时域特征点和备特征点脉搏信号变化的快慢。结果：通过对30例年龄在20-25之间健康人脉象时域特征点过零点位置的统计和其变化快慢的计算．准确定位了其脉象时域特征点过零点位置。结论：应用这种方法可以比较准确地分析脉象信号所携带的各种信息，从而为中医脉诊客观化提供了一种新方法。

| Abstract: | Objective To find a new objectified method for pulse diagnosis. Method According to the relationship between the wavelet transform zero-crossing point and signal saltation site, this paper detects time domain feature points and corresponding saltation velocity of pulse signals. Result With 30 normal subjects 20-25 years old involved in, the wavelet transform zero-crossing points are positioned. Conclusion This method can be applied to analyze all kinds of information contained in pulse signals, and thus is qualified for objectification of pulse diagnosis. |
