| 摘 要： | 本文采用分子动力学模拟（Molecular Dynamics simulation简称MD）方法对不同磁场和温度条件下水体系的表面张力系数进行了计算。结果表明水的表面张力系数和磁感应强度之间具有多极值关系,特别在常温下以及磁感应强度为0.25T时,磁场对水体表面张力系数的影响最为明显。通过对径向分布函数的计算发现,磁场可以影响g(r)的分布,使水的结构发生变化,从而导致水的表面张力系数发生改变。

| Abstract: | Molecular dynamics simulations were performed in 256 water molecules under different magnetic fields. The surface tension and radial distribution function of water have been calculated. The research results indicated that the relation between internal energy and magnetization is multi-peak, the effect of magnetization is the most distinct under the condition of B=0.25T and at room temperature. |
