摘要
用延迟方法、由实验得到的时间序列重构系统的相空间，绘制了人体心搏吸引子．研究结果表明：健康人心脏搏动的相空间运动轨迹是一奇怪吸引子；而吸引子空间范围的缩小或周期和准周期吸引子与某些疾病相联系．
By delay methd,the phase space of the system is reconstructed from the time seriesof the experimental data. The phase space attractors of heart beat are drawn. The resultsindicate that the movement locus in phase space of a healthy heart is a strange attractor,while the reduction of the attractor space range or periodic and quasi-periodic attractors of-fen relate to some diseases.
