我们详细阐述了嵌入自收缩主体介质中的碳纳米管的横截面变形。使用连续弹性方法来计算嵌入纳米管和有限厚度的自收缩外部介质的机械能。我们的公式使我们能够评估施加在嵌入纳米管和外部收缩介质之间的界面上的临界径向压力以及紧邻临界压力之上出现的变形模式。通过建立的理论方法推导出嵌入效应的一个有趣的力学含义，即临界压力对介质弹性模量的幂律依赖性。
We elaborate on the cross-sectional deformation of carbon nanotubes embedded into a self-contracting host medium. The continuum elastic approach is used to formulate the mechanical energy of both the embedded nanotubes and the self-contracting outer medium with finite thickness. Our formula allows us to evaluate the critical radial pressure applied on the interface between the embedded nanotube and the outer contracting medium as well as the deformation mode that arises immediately above the critical pressure. An interesting mechanical implication of the embedding effect, that is, the power-law dependence of the critical pressure on the elastic modulus of the medium, is deduced by the theoretical approach established.
