The acute angle between the direction of the undisturbed relative wind and the chord of an airfoil. 相对稳定的风的方向与机翼弦之间的锐角。
Crown profile models, including branch diameter, branch length, angle of origin, and branch chord length, were developed from branch attributes and tree variables. 基于枝条着枝深度(DINC)和林木变量所建立的树冠形状模型包括:基径、枝长、着枝角度和弦长等预估模型。
