In 1978 Wolfgang Helfrich published a paper (Helfrich W. Z Naturforsch 1978; 33a:305) where he introduced the notion of an undulation force between bilayers. This is caused by thermal excitations of the bending modes being restricted by the presence of neighboring layers. Although there is now a consensus on the qualitative picture put forward by Helfrich there is still a debate concerning the quantitative aspects. We discuss in particular the distance dependence of the interaction and also the value of the numerical coefficient of the force law derived by Helfrich.
1978 年，沃尔夫冈·赫夫里希（Wolfgang Helfrich）发表了一篇论文（Helfrich W. Z Naturforsch 1978; 33a:305），其中他提出了双层之间的波动力的概念。这是由弯曲模式的热激发受到相邻层的限制引起的。尽管现在对于赫夫里希提出的定性图像已经达成共识，但关于定量方面仍存在争议。我们特别讨论了相互作用的距离依赖性以及赫夫里希推导的力定律的数值系数的值。
