摘要 通过半经验势分子动力学模拟在(N,V,T)系统下计算出尿嘧啶分子中的每个原子随时间演化过程时的位置,速度,受力的大小、方向与键长,键角的变化.从而得到在目前由于技术等原因的限制而在实验当中很难或无法得到的相关粒子的微观数据.为更近进一步了解分子内部运动提供理论基础. Under the (N, V, T) system, the position, speed, strength and direction of under stress and the changes of bond distance and bond angle of the evolution of each atom in uracil molecule are calculated by using the semiempirical molecular dynamics. The calculations come to the conclusions which are difficult or failed to be obtained on the microcosmic information of particles during the experiment because of the limit of today’s technology. It is to provide the theoretical basis that will go a step further to know molecular inner dynamics.
