本文对犬、猫、兔的主动脉在体及切除后即刻的横截面、相对厚度、纵、周向扩张及传播速度进行了测量。还对狗的主静脉和肺动脉进行了一些测量，结果表明这三种血管在扩张时具有可比的弹性模量。除了少数例外，主动脉横截面与相应的流量相当（例如，如Levy和Blalock的测量结果所示），并且仅在少数区域（包括近端降主动脉、腹腔动脉轴和髂动脉分叉）具有明显的锥度。在体内和切除后不久获得了可比的测量结果，两者都显示了遗传杂种人群中的广泛个体差异。
Cross sections, relative thicknesses, longitudinal and circumferential distensibilities and propagation velocities of main arteries of dogs, cats and rabbits were measured in vivo and shortly after excision. A few measurements of main veins and pulmonary arteries were also made in the dog and indicated that the three types of vessels have comparable moduli of elasticity in distension. With a few exceptions, the main arterial cross sections are commensurate with the corresponding flows (as shown by Levy and Blalock''s measurements, for example) and have marked tapers in only a few regions (which include the proximal descending aorta, the celiac axis and the iliac bifurcation). Comparable measurements were obtained in vivo and soon after excision, and both showed wide individual variations among the genetically mongrel population.
