采用蒙特卡罗方法研究了具有外弯曲刚度-kappa的自回避流体膜的构象和标度性质。对于kappa = 0，结果与大长度尺度下的支化聚合物行为一致。随着Kappa值的增加，系统从皱曲状态到伸展状态有一个平滑的过渡，当持续长度达到系统尺寸时，比热达到峰值。对于所有的裸刚度，尺度相关的有效弯曲刚度是系统尺寸的递减函数。这些结果表明，流体膜总是皱在足够长的长度尺度。
The conformation and scaling properties of self-avoiding fluid membranes with an extrinsic bending rigidity-kappa were studied with the use of Monte Carlo methods. For kappa = 0, the results are consistent with branched polymer behavior at large length scales. There is a smooth crossover from a crumpled to an extended state with increasing kappa, with a peak in the specific heat when the persistence length reaches the system size. The scale-dependent effective bending rigidity is a decreasing function of system size for all bare rigidities. These results indicate that fluid membranes are always crumpled at sufficiently long length scales.
