脉象方程的数值模拟方法

承文献［１］，建立了脉象方程的一种半解析半数值模拟方法。对多种弯曲位形血管，在不同脉压激励下，模拟结果显示人体自然脉象极为复杂、多变，也存在明显的规律性。当系统物理和激振源参数给定时，自然脉象性态会随管形和观测点位置而变，在特定条件下会取得与激励脉压波完全相似的波形，但其最大振幅远大于径向胀缩位移波的幅值，与已有实验［２，３］结果吻合。

Numerical Simulation of the Pulsocondition Equation

After1], a semi-analytic-numerical simulation is proposed. A great number of examples show that the method is very usefull and convenient. For many curved configuration of vessel excited by variform arterial pressure, the results reveal that the natural pulsocondition in the body has a very complex and variable feature but also exhibits some evident regularity. When the physical system and excited source parameters are given the beharvior of natural pulsocondition may be variated with the configuration of vessel and the ovserving position. Under specified conditions, the pulsocondition can get similar wave form as well as the arterial pressure inside the vessel at Cunkou. But its amplitude is far greater than the swelled displacement in the radial direction, which comforms to the existing experiments2]3].
