Equations reflecting relationships between the thickness of blood vessel wall (w) and internal radius (r) of the vessel during the process of smooth muscle fiber contraction involved two types of the fibers orientation in vessel wall: at an angle of 45 degrees and 90 degrees to the longitudinal axis of the vessel. Experimental values of w and r were determined on arterioles of the rat mesentery after vasopressin or epinephrine administration. According to the degree of longitudinal and transversal efforts participation in the process of vessel closure, heterogeneity of the arterioles was revealed by comparison of the theoretical and experimental values of w and r. The ability of arterioles for closure did not depend on the initial value of relative vessel wall thickness (w/r).
反映血管平滑肌纤维收缩过程中血管壁厚度（w）与血管内径（r）之间关系的方程涉及血管壁中两种类型的纤维取向：与血管纵轴呈45度和90度角。在给予血管加压素或肾上腺素后，在大鼠肠系膜小动脉上测定w和r的实验值。根据纵向和横向作用力参与血管闭合过程的程度，通过比较w和r的理论值与实验值揭示了小动脉的异质性。小动脉的闭合能力不取决于血管壁相对厚度（w/r）的初始值。
