摘要
采用ＭＣ法研究了ＮａＣｌ熔体在电场作用下的微观结构．结果表明，在电极表面存在着完全不同于水溶液的双电层结构，其第一配位层为整齐排布的Ｃｌ－离子，第二配位层为间隙排列的Ｎａ＋离子，而在距电极大于２（Ｒ＋＋Ｒ－）的熔体内部仍符合Ｂｏｌｔｚｍａｎｎ分布．
Monte Carlo method was applied to the investigation on the microstructure of NaCI melts underthe action of electric field through computer simulation. It was found that there are electric double layers onthe surface of electrodes and they are significantly different froal those of aqueous solution. The first lay6rpresents that CI--ions are arranged in order,and the second layer presents that Na+ ions in gapped arrangement. However,the structures inside the melts at a distance greater than 2(R+ +R-- )from electrode surfaceare still in compliance with foltzmann distribution.
