摘要
The differences between the actual equations of molecular dynamics method (MD) and the Newtonian ones due to numerical integration errors are analyzed. Condition of total energy conservation in MD is obtained. The simplest schemes satisfying this condition and the total energy fluctuations in MD are considered. Statistical meaning of MD and possible analogies of the MD equations in real molecular systems are discussed.
