Since the pure cylindrical vesicles without ends are unstable even non - existence , approximations of torus and cylinder with spherical ends are utilized . the result from the former approximation means the condition of infinite long cylinder , which gives us no useful information . by spherically topological approximation , we get a set of conditions , all of which specify the range of parameters
利用环拓扑结构近似，我们得到了无限长柱状膜的方程，但此方程没有给出任何有用的信息；利用球拓扑近似，无论直接变分还是间接变分，都给出了一组条件，规定了参数的一个取值范围，所以，球拓扑近似比环拓扑近似更实用一些。
