摘要翻译:
描述了两种模拟双层,并报告了侧向张力和分子间作用力对侧向张力的部分贡献的结果,报告并讨论了每个表面活性剂头部从隧道形成到无张力状态、转变到软化双层直至其解体的最大可能范围的面积数据。讨论了无张力状态的意义。结论:(1)无张力状态是一个巧合;(2)从伸展到软化双层的转变发生在附近,具有相变的特征;(3)没有这种转变的理论;(4)软化双层的横向张力随大小而变化;扩展双层的大小不依赖于尺寸。(4)鼓形模型不适用于界面,因为这些界面是通过扩散波动的。(5)回转半径也是如此!显示不连续。

英文摘要:
Two kinds of simulated bilayers are described and the results are reported for lateral tension and for partial contributions of intermolecular forces to it.Data for a widest possible range of areas per surfactant head, from tunnel formation through tensionless state, transition to floppy bilayer,to its disintegration, are reported and discussed. The significance of the tensionless state, is discussed. Conclusions: (1) the tensionless state is a coincidence;(2) the transition from extended to floppy bilayer occurs nearby and has hallmarks of a phase transition (3) there is no theory of that transition.(4)The lateral tension of the floppy bilayer scales with size; that of the extended bilayer does not depend on size. (4) The drumhead model not appropriate for interfaces as these fluctuate via diffusion.(5) The radius of gyration also! shows a discontinuity.
