Polyester resin casts were made of the bronchial trees from three adult dogs. The branches were ordered by the method of Strahler and the number of branches in each order counted. The length and diameter of each branch was measured and the mean dimensions of branches in each order calculated. When number, mean diameter and mean length of branches in each order are plotted semilogarithmically against order, linear relationships are found. From the data thus obtained a dimensional model of the dog's bronchial tree has been developed.
用三只成年犬的支气管树制作了聚酯树脂铸型。按照斯特拉勒方法对分支进行排序，并计算每个等级的分支数量。测量每个分支的长度和直径，并计算每个等级分支的平均尺寸。当将每个等级分支的数量、平均直径和平均长度以半对数形式相对于等级作图时，可发现线性关系。根据由此获得的数据建立了犬支气管树的尺寸模型。
