It is shown that the mechanical properties including Young's modulus, tensile strength, critical strain and stress under buckling can be enhanced with the decreasing of intershell spacing. The shear strength can be enhanced by 2-3 orders of magnitude when the intershell spacing is reduced to 20%, which is also dependent on commensuration. Zigzag-type carbon nanotubes have higher shear strength. The axial stress in tubes when the load transferring from outmost tube to inner tube is observed as well.

研究了单壁纳米管束横截面的六方化失稳现象，给出各种管径的面内压力－应变关系曲线；每条曲线都给出一个明显的拐点而且有很强的非线性；线弹性模量与参考构形有关，也受管直径的影响；分析了管束横截面的晶格不稳定性特征，表明晶格的缺陷能够明显的减小临界值；模拟了在不同应变下纳米管束对静水压的反应，发现不同压力下的截面形态不同，在很高压力下相邻管之间会形成化学键。

The results indicated that the centrifugal force reduces the localization; when the Young's modulus of all blades are in the tolerance of 5%, the blade-disc can regarded as an cyclic symmetry system. The study results given in the present paper have provided a variety of effective numerical methods for the study of vibration characteristics of blade, disc and the blade-disc system. These research results can also serve as a helpful guide to the vibration study of other rotating components.

随着碎屑颗粒粒径的增大，即由砂质泥岩、粉砂岩向砂岩过渡，粗粒的粒柱状矿物逐渐增加，而细粒的片状矿物逐渐减少，岩石的强度和刚性增强，在集中应力作用下，弹性能指数增大，发生脆性破坏的可能性增大及破坏持续的时间变短也更猛烈，岩石的冲击倾向性增强。
