原子是保持完整通过象化学契约那样的短范围相互作用和电磁的相互作用形成不同材料和设备。当分子的力学和动力学基于实验潜力能在大规模模仿材料行为时，量力学是强大的在纳米规模描述材料的短范围相互作用，但是在包括费用转移和再分配过程处理弱，例如功能的 nanomaterials ，塑料变丑，骨折和 nanomaterials 的阶段转变的机械电的联合。这些问题对需要被延长到货车 der Waals 距离和更大的空间以及时间的规模的量力学也挑战性。这里，我们使一些的这种机械行为上的简短评论和讨论成为重要功能的 nanomaterials 和 nanostructures，到探查到多尺度的物理力学的 nanomechanics 和趋势的边疆。

英文摘要：

Atoms are hold together to form different materials and devices through short range interactions such as chemical bonds and long range interactions such as the van der Waals force and electromagnetic interactions. Quantum mechanics is powerful to describe the short range interactions of materials at the nanometer scale, while molecular mechanics and dynamics based on empirical potentials are able to simulate material behaviors at much large scales, but weak in handling of processes including charge transfer and redistributions, such as mechanical-electric coupling of functional nanomaterials, plastic deformation~ fracture and phase transition of nano- materials. These issues are also challenging to quantum mechanics which needs to be extended to van der Waals distance and larger spatial as well as temporal scales. Here, we make brief review and discussions on such kind of mechanical behaviors of some important functional nanomaterials and nanostructures, to probe the frontier of nanomechanics and the trend to multiscale physical mechanics.
