【摘要】:脈搏波是人體重要的生理信號(hào)之一,從新的角度探索脈搏波的分析手段是脈搏波研究的一個(gè)重要方向.在分析現(xiàn)有脈搏波時(shí)域、頻域分析方法的基礎(chǔ)上,將復(fù)雜網(wǎng)絡(luò)的分析方法引入脈搏波的分析之中,以拓展脈搏波的研究維度.分析了時(shí)間序列的網(wǎng)絡(luò)化方法的現(xiàn)狀,選擇使用基于水平可見性(horizontal visibility graphs,HVG)的網(wǎng)絡(luò)化方法對(duì)脈搏波進(jìn)行網(wǎng)絡(luò)化分析.獲得使用脈搏波構(gòu)建的網(wǎng)絡(luò)的特性參數(shù),確定了脈搏波網(wǎng)絡(luò)的無標(biāo)度特性,并從生理狀態(tài)的角度進(jìn)行了解釋,為脈搏波的研究提供了一種新的手段.
[Abstract]:Pulse wave is one of the most important physiological signals in human body. It is an important direction to explore the analysis method of pulse wave from a new point of view. Based on the analysis of the existing pulse wave analysis methods in time domain and frequency domain, the complex network analysis method is introduced into the pulse wave analysis, in order to expand the research dimension of pulse wave. This paper analyzes the present situation of the networked method of time series, and chooses the networked method based on horizontal visibility (horizontal visibility graphs,HVG to analyze the pulse wave network. The characteristic parameters of the network constructed by pulse wave are obtained, the scale-free characteristic of pulse wave network is determined and explained from the point of view of physiological state, which provides a new method for the study of pulse wave.
