摘要: 用Monte-Carlo计算机模拟方法,通过对一个含有64个水分子的三维体系在磁场作用时内能变化的计算,定量评估了磁场强度及温度对磁处理效应的影响。研究发现:水的内能与外加磁场强度的关系曲线是一条多极值曲线;水-水径向分布函数伴峰的高度与磁感应强度也具有多极值特征;计算机模拟结果与实验结果基本一致,计算机模拟确实是从分子水平研究磁处理机理的有效方法。

Abstract: Effect of a magnetic field on potential energy of liquid water are investigated for first time using classical Monte-Carlo computer simulation and a water model L-J. The relationships between energy and magnetic flux density and temperature have been studied by calculating potential energy and radial distribution function (RDF) of a system containing 64 water molecules. Comparisons with the field-off system are made throughout. It is found that the computer simulation is in agreement with experimental results.

Key words: computer simulation, magnetic field, water, Monte-Carlo, potential energy
