Successive points turn by the golden angle, about . This irrational fraction of a full turn avoids repeated radial alignments; makes the area enclosed grow linearly with point count.相邻点转过约 的黄金角。它占整周的比例是无理数，因此不会周期性地落在同一射线上； 使圆内面积随点数线性增长。
The bright points appear in placement order. Two families of visible spirals emerge from this one angle-and-radius rule, a common model of sunflower seed arrangements.亮点按放置顺序出现。仅凭这一组转角与半径规则，就会浮现两组旋向相反的螺旋，这是向日葵种子排列的一种常用模型。
