The quasistatic and dynamic elastic behaviour of the tail artery of male normotensive (NCR) and spontaneously hypertensive (SHR) rats was determined in vitro. The tone of the smooth muscle was enhanced by norepinephrine and diminished by papaverine. The circumferential wall stress was changed by varying the transmural pressure level. The experimental procedure was the same as that used in a previous investigation (Bauer and Pasch, 1971). The circumferential (tangential) elastic wall modulus Et was calculated from the mean internal and external radii determined at each pressure level and from dynamic pressure-volume recordings in the frequency range between 0.03 and 20 HZ. The calculation was based on a formula valid for thick-walled, longitudinally constrained vessels.
在体外测定了雄性正常血压（NCR）大鼠和自发性高血压（SHR）大鼠尾动脉的准静态和动态弹性行为。去甲肾上腺素增强平滑肌张力，罂粟碱减弱平滑肌张力。通过改变跨壁压力水平来改变周向壁应力。实验程序与先前研究（Bauer和Pasch，1971）中使用的相同。周向（切向）弹性壁模量Et由在每个压力水平测定的平均内半径和外半径以及在0.03至20赫兹频率范围内的动态压力-容积记录计算得出。该计算基于一个对厚壁、纵向受限血管有效的公式。
