我们研究了由水溶性表面活性剂制成的管状流体膜的不稳定性。小管是在高盐水盐度下获得的。不稳定性是由于在囊泡多层内引入烷烃。我们测量这种不稳定性的波长与未受干扰的半径的小管和解释这种选择通过使用一个模型，不仅包括在弹性能量的表面张力，但也引起的油作为一个自发的曲率的不对称性的影响。线性稳定性分析表明，在这个模型中的选择确实是由于非零的正自发曲率。【S1063-651X（98）03712-X】。
We investigate the instability of a tubular fluid membrane made of a water-soluble surfactant. The tubules are obtained at high brine salinities. The instability is due to introduction within the vesicle multilayer of an alkane. We measure the wavelength of this instability versus the unperturbed radius of the tubules and interpret this selection by using a model that includes not only the surface tension in the elastic energy, but also the effect of the asymmetry induced by the oil as a spontaneous curvature. The linear stability analysis shows that within this model the selection is indeed due to nonzero positive spontaneous curvature. [S1063-651X(98)03712-X].
