Abstract
A model is postulated which attributes the distinctive biconcave shape of the human erythrocyte to a balance of forces acting on the membrane. The forces considered are electrostatic forces due to a charge distribution on the membrane, a hydrostatic pressure difference acting across the membrane, and forces arising from a constant tension in the membrane. A numerical study indicates that the postulated model will produce an equilibrium shape which is very similar to the observed shape of the human erythrocyte.
摘要
假定了一个模型，该模型将人类红细胞独特的双凹形归因于作用于细胞膜上的力的平衡。所考虑的力包括由于细胞膜上电荷分布产生的静电力、跨膜作用的静水压力差以及由细胞膜中恒定张力产生的力。一项数值研究表明，假定的模型将产生一种与观察到的人类红细胞形状非常相似的平衡形状。
