摘　　要：本文从血管壁的构造和血管壁体积?压力关系解释了血管硬化指数(ASI)的测量原理,在测量时得到上臂袖带放气过程中袖带压结合脉搏波形的信息,取最大峰值前后最近似80%最大峰值的两个脉搏波峰所对应的袖带压差值作为基准参数值。据此方法制作的测量仪器通过临床测试,证明了测量方法的实用性和可靠性。This paper expounds the principle of the arterial stiffness inde~ （ASI） through the artery wall structure and the relation of the volume - pressure in vessel. By examining the cuff pressure and pulse wave signals of the fall - off pressure in the cuff on the upper arm, the basal parameter is calculated as the pressure width of the cuff pressure curve at 80% of the peaks of the pulse wave. Clinical test and analysis are performed in the hospital to verify the practicability and reliability of the measuring apparatus on the measurement method
