One is a micelle that may be depicted as a ball with the lipid polar groups on the outside and the hydrocarbon chains pointing together, the other a lipid bilayer.

一为胶束，它可以被描述为类脂极性基团在外而烃链挤到一起的小球；另一个即为类脂双层。

Another popular solution is to take a double layer of bed linen about the size of the long scarf.

Helfrich firstly proposed the spontaneous curvature model based on the similarities of the lipid membrane and the nematic phase liquid crystal,thus proved the existence of the biconcave shape.

Helfrich根据向列相液晶与类脂膜的相似性，于1973年最先提出了膜的自发曲率弹性理论，并由此证明了膜的双凹盘形的存在；同时，考虑到膜泡双层间的面积差对膜泡能量的影响，1989年S。
