Abstract
Assuming that the shape of red blood cells is controlled by the curvature elasticity of the surrounding membrane, we fit theoretical shapes to the contours Evans and co-workers determined by interference microscopy. Very good agreement is obtained for disc shapes. The fit is not so good for less common shapes, which may result from Evans' parametric representation and from the interference of shear elasticity.
摘要
假设红细胞的形状由周围膜的曲率弹性控制，我们将理论形状与埃文斯及其同事通过干涉显微镜测定的轮廓进行拟合。对于圆盘状形状，获得了非常好的一致性。对于不太常见的形状，拟合效果不太好，这可能是由于埃文斯的参数表示以及剪切弹性的干扰所致。
