组间波形相似度及在中医推拿?法 垂直作用力信号分析中的应用

目的 研究表征同类信号不同组间波形相似程度的定量指标，并应用于中医推拿?法垂直作用力信号分析。方法 对两列同类周期信号序列归一化和波形误差分析后，定义表征同类信号不同组间波形相似程度的组间波形相似度。实测著名推拿医师、已学习中医?法一段时间的研究生和?法初学者3组操作者的法垂直作用力信号，计算3组信号的组间波形相似度，分析他们的相似程度。结果 数位推拿医师之间的?法垂直作用力信号组间波形相似度较高，可作为其他?法垂直作用力信号与之比较的模板，研究生和医师之间的相似度次之，初学者与医师之间的相似度最低，三者有显著性差异。结论 本文提出的组间波形相似度可以作为评判中医推拿?法垂直作用力信号不同组间波形相似程度的定量指标，也可应用于其他近周期信号组间波形的相似程度评判。

Waveform similarity and its application to the vertical force signals analysis on rolling manipulation

Objective To raise a quantitative indicator for the waveform similarity between different signals of the same kind and apply it to the analysis on the vertical force signals from the rolling manipulation.Method After two signals of the same kind were normalized and their waveform errors were analyzed,the waveform similarity,which was to be utilized to describe the extent to which two signals were similar to each other,was defined.Then,the vertical force signals of the rolling manipulation operated by severa...
