| 摘 要： | 马德隆常数是离子晶体结构的一个重要特征参数.采用埃夫琴晶胞推导了计算二维三角离子晶体的马德隆常数的通项公式.计算结果表明:二维三角离子晶体的马德隆常数比二维正方离子晶体的小,而比一维离子晶体的大,从而验证了马德隆常数随着晶体配位数的增加而增大的论断.

| Abstract: | Madelung constant is an important characteristic parameter for ionic crystal structure.By Evjen crystal cell,the calculation formula about Madelung constant for the two-dimensional trigonal ion crystal was deduced.The calculation result indicated that Madelung constant for the two-dimensional trigonal ion crystal was smaller than that for the two-dimensional square ion crystal,and was larger than that for the one-dimensional ion crystal,which proved that Madelung constant increased with the increase of crystal coordination number. |
