9900127ZengA systematic computational exploration of the behavior and properties of nanoscopic particles that could function as nanomachine parts is proposed. The study comprises three phases: (1) the mechanically controlled movement of nanoparticles over substrates; (2) the "lubrication" of nanoparticles by simple fluids; (3) chemical reactions mechanically induced by the movement of nanoparticles over one another. The principal tool is atomistic computer simulation based on Monte Carlo techniques.As technology for the construction of mechanical elements advances toward the nanoscale, the drive to build machines with controllable moving parts of nanoscopic dimension mounts. The operation of such machines is expected to be very different from their macroscopic coun-terparts. The goal of this research is to understand the fundamental basis for the behavior of nanomachine parts under the conditions likely to be necessary for their fabrication and for the effective functioning of the machines that they would make up.***

9900127 Zeng提出了对可以用作纳米机器部件的纳米级颗粒的行为和性质的系统计算探索。该研究包括三个阶段：（1）纳米粒子在基底上的机械控制运动;（2）简单流体对纳米粒子的“润滑”;（3）纳米粒子相互运动引起的机械化学反应。主要工具是基于蒙特卡罗技术的原子计算机模拟。随着机械元件制造技术向纳米级发展，制造具有纳米级尺寸可控运动部件的机器的动力越来越大。这种机器的操作预计将非常不同于宏观的对手。这项研究的目标是了解纳米机器部件在其制造和机器有效运作所需的条件下的行为的基本基础。
