结果表明，粘结在衬底上的平面单分子层的最小屈曲力对应的第一屈曲模式可能不是光滑的。由此产生的相邻分子的锯齿状构型导致了分子水平上的波纹，我们将这种现象命名为纳米皱折。导出了这种光滑-非光滑过渡的判据。该模型还可以描述由于收缩而导致的完美晶体的表面不稳定性。
It is shown that the first buckling mode corresponding to the lowest buckling force of a plane monomolecular layer glued to a substrate may not be smooth. The resulting saw-like configuration of neighboring molecules leads to corrugation on a molecular level and we name such a phenomenon nanobuckling. A criterion governing this smooth-not smooth transition is derived. The model presented may also describe surface instability of a perfect crystal due to contraction.
