摘　　要：本文通过研究主动脉容积变化微分方程,导出了心阻抗图与心脏射血的非线性函数关系。由此得到的三个推论,与实验结果基本一致。This paper derived a non-Linear function relationship between the cardiac impedance plethysmogram and the heart ejection by researching differential equation of the aortic volume change. We derived three inferences from the above relationship. They essentially conform with experimental resuits.
