Abstract
Examining botanical trees, Leonardo da Vinci noted that the total cross section of branches is conserved across branching nodes. In this Letter, it is proposed that this rule is a consequence of the tree skeleton having a self-similar structure and the branch diameters being adjusted to resist wind-induced loads.
摘要
研究植物树木时，列奥纳多·达·芬奇注意到，树枝的总横截面积在分支节点处保持守恒。在这封信件中，有人提出，该规则是树木骨架具有自相似结构的结果，并且分支直径被调整以抵抗风致荷载。
