1. Driven by high frequency and multi-directional shot peens, dislocations of various orientations proliferate into the metal, and accumulate in high density in the surface layer of a shallow depth. Migration, generation and annihilation of dislocations dictate the evolution of mobile dislocation density.
无论是对低维基本物理以及其中新奇量子现象的探索与认识，还是微电子工业水平的持续发展，都迫切地需要掌握一种能够精确、可靠地操控表面纳米结构的方法。
