中文摘要：
目的：探讨脉势与桡动脉运动周期功率之间的关系。方法：应用NX-1型中医取脉装置，同步采集39例不同脉势病人和20例平人关部脉的压力脉图和心电信号；以心电信号为R波周期标志，在MATLAB7．0．1软件的SPTool分析工具对桡动脉压力信号进行FFT分析处理的基础上，观察不同脉势下心动周期内桡动脉压力信号功率（周期功率）的变化情况。结果：不同脉势的脉象周期功率具有明显差异，实变脉〉平脉〉虚变脉。结论：桡动脉运动周期功率是判别脉势的可能依据。
英文摘要：
Objective： To study the relationship between different pulse forces and cyclical power （CP） of radial artery motion. Methods： 39 patients＇ and 20 healthy persons＇ ECG and pressure sphygmograms were collected synchronously with NX-1 sphygmograph. On the basis of automatic detecting R waves of ECG and FFT analysis of pressure sphygmograms with SPTool of MATLAB 7.0.1, change in frequency domain of radial artery motion with different forces was observed and CP was worked out. Results： There is significant deviation between CP of pulse tracings with different forces （ pulse tracings with powerful force 〉 pulse tracings with normal force 〉 pulse tracings with weak force ） . Conclusion： CP of radial artery motion can be used to discriminate pulse force.
