论文摘要
通过拉动脊椎几乎不可能分开两本交错的电话簿。组件外部纸张施加的非常轻微的力被放大为纸张数量的正方形的指数，即使有少量的板也导致了高度抗性的系统。我们介绍了一项系统，详细的研究，对正常外力的影响以及小册子的几何参数对组装强度的影响。我们得出的结论是，两个外部床单之间的纸纸粘附力在几个MN的范围内是由两个交错系统放大的纸质粘附力。两手册实验吸引了世界各地的学生和非科学公众的关注，这是对摩擦强度的出色表现，似乎也是微观摩擦粘附偶联的宏观宏观表现。
Two interleaved phonebooks are nearly impossible to separate by pulling their spines. The very slight force exerted by the outer sheets of the assembly is amplified as the exponential of the square of the number of sheets, leading to a highly-resistant system even with a small number of sheets. We present a systematic and detailed study of the influences of the normal external force and the geometrical parameters of the booklets on the assembly strength. We conclude that the paper-paper adhesion force between the two outer sheets, on the order of a few mN, is the one that is amplified by the two interleaved system. The two-phonebooks experiment that has attracted the attention of students and non-scientific public all around the world as an outstanding demonstration of the strength of friction appears to be as well a spectacular macroscopic manifestation of the microscopic friction-adhesion coupling.
