摘要
运用分子动力学方法研究了电流变液的在外电场下的液──固相变过程，原子间的相互作用采用简单偶极势来描写。计算结果表明：对于一个给定的外电场，当系统温度逐步降低的时候，电流变液中的颗粒首先会沿电场方向排列成键状结构，然后逐步转变成块状体心四方结构。研究结果与作者前期用统计力学方法所得结论相一致，也与实验结果比较吻合。
By using molecular dynamics method, we examine the solidification procedure of Electrorheo logical fluid. The simulations indicates, for a given external field, when the temperature of system drops grad ually, the particles of ER frist fluid form chain - link structure, and then tum into BCT lattices structure. We also find the applied eIectricaI field and the contrast of the dielectric constants of the particles. The fluids also influence the nuid - solid transformation. The present results are in accordance with our preceding results ob tained through statistical approach, as expected in the experiment.
