然而，板块构造不能完全解释某些巨大的地表特征，例如非洲南部的“superswell”，即一个直径超过1000英里、高度接近1英里的巨大高原。
However, plate tectonics cannot fully explain certain massive surface features, such as the "superswell" of southern Africa, a vast plateau over 1,000 miles across and nearly a mile high.
为了更好地表现树木在自然环境中的生长形态，在基于直径变化率的趋向性力学模型基础上，提出了一种模拟树木生长的综合力学模型。
In order to show the trees better in nature, based on diameter variety rate mechanical model, tree growth simulation 's integrated mechanical model is proposed.
