摘　　要：传统生理学教科书中"动脉血压随着远离心脏而逐渐降低"的相关表述不够准确。大量研究表明,动脉收缩压和脉压在由中心动脉向外周大动脉这一区段传播的过程中不仅没有逐渐降低,反而逐渐升高。这一现象可能与脉搏波反射等因素有关。笔者呼吁传统教科书中的相关表述应予以修正,使之更加准确,以避免对广大医学生或临床医生造成误导,同时脉搏波反射具有重要的生理及临床意义,应予进一步重视。The traditional physiology textbooks hold the opinion that arterial blood pressure gradually decreases as it moves away from heart,which we think is not precise saying. A large number of studies have shown that the arterial systolic pressure and pulse pressure will gradually increase during the pressure wave transmitting from aorta to the peripheral large arteries. This phenomenon can be explained by pulse wave reflection theory. This paper suggests that the relevant expressions in traditional textbooks should be corrected to make them more accurate,so as to avoid misleading medical students or clinicians. Pulse wave reflection has potential physiological and clinical significance,which should be paid more attention to.
