利用Helfrich自发曲率模型的弹性力学理论，采用切角摄动法研究了大尺度球形囊泡在压力变化下的轴对称变形。在轴对称形状方面得到了三个主要结果：双凹形状、花生形状和一种类型的髓鞘。这些轴对称的形态变形是一致的，在lipsome实验中观察到的暗场光学显微镜和在红细胞中观察到的两个细丝（髓鞘）在生活状态。此外，双凹形状和花生形状可以模拟的帮助下，一个强大的软件，表面进化，其中可以很容易地考虑自发曲率。
With tangent angle perturbation approach the axial symmetry deformation of a spherical vesicle in large under the pressure changes is studied by the elasticity theory of Helfrich spontaneous curvature model. Three main results in axial symmetry shape: biconcave shape, peanut shape, and one type of myelin are obtained. These axial symmetry morphology deformations are in agreement with those observed in lipsome experiments by dark-field light microscopy and in the red blood cell with two thin filaments (myelin) observed in living state. Furthermore, the biconcave shape and peanut shape can be simulated with the help of a powerful software, Surface Evolver, in which the spontaneous curvature can be easy taken into account.
