摘要
纳米有序体系膜（超薄膜即膜厚趋于分子量级）［５］的摩擦特性与宏观薄膜有很大的不同，但与纳米有序膜的微观结构有密切的关系。利用分子动力学模拟方法可以研究超薄膜（纳米有序体系膜）宏微观特性，本文主要研究了用，ＶＣ＋＋６．０与ＯｐｅｎＧＬ结合模拟纳米有序膜的微观运动状态和特性，模拟纳米有序膜的失效机理，显示分子膜结构的变化对分子膜摩擦力的影响。同时，纳米有序膜系统中的能量损失也可得到。
The properties of the Nano-LB film (the ultra-thin film) are distinctly different from that of the macro thin film. The method of molecular dynamics simulation plays a key role in studying both microstructure and macro properties of the ultra thin film. Computer simulations of atomic process based on VC and OpenGL often provide a valuable method for interpreting experimental results, simulating micromotions of ultra-thin film, analyzing characteristics of ultra-thin film and explaining new phenomena. The simulations suggest, however, that these changes in microstructure have efffect on the friction properties of ultra-thin film. Also, the mode of energy dissipation in this system is examined.
