    "abstract": "With tangent angle perturbation approach the axial symmetry deformation of a\nspherical vesicle in large under the pressure changes is studied by the\nelasticity theory of Helfrich spontaneous curvature model.Three main results in\naxial symmetry shape: biconcave shape, peanut shape, and one type of myelin are\nobtained. These axial symmetry morphology deformations are in agreement with\nthose observed in lipsome experiments by dark-field light microscopy [Hotani,\nJ. Mol. Biol. 178, (1984) 113] and in the red blood cell with two thin\nfilaments (myelin) observed in living state (see, Bessis, Living Blood Cells\nand Their Ultrastructure, Springer-Verlag, 1973). Furthermore, the biconcave\nshape and peanut shape can be simulated with the help of a powerful software,\nSurface Evolver [Brakke, Exp. Math. 1, 141 (1992) 141], in which the\nspontaneous curvature can be easy taken into account.",
