收集了15种铁-镁电气石的晶体结构数据,计算了固有电偶极矩,分析了铁-镁电气石的固有电偶极矩与铁含量、价态及分布的关系.结果显示:电气石中沿着c轴方向的固有电偶极矩随着Fe3+离子总数、特别是Y位置上Fe3+离子数的增加而减小,随Y位置上Fe2+离子数的增加而略有增加.
收集瞭15種鐵-鎂電氣石的晶體結構數據,計算瞭固有電偶極矩,分析瞭鐵-鎂電氣石的固有電偶極矩與鐵含量、價態及分佈的關繫.結果顯示:電氣石中沿著c軸方嚮的固有電偶極矩隨著Fe3+離子總數、特彆是Y位置上Fe3+離子數的增加而減小,隨Y位置上Fe2+離子數的增加而略有增加.

Crystal structure data of 15 iron-magnesium (Fe-Mg) tourmalines have been collected and their intrinsic dipole moments have been calculated. The correlation between the content, valence and distribution of Fe in Fe-Mg tourmalines and their intrinsic dipole moments have been analyzed in detail. The results show that the intrinsic dipole moments along the c axis in Fe-Mg tourmalines decrease with the increasing of their Fe3+ content, especially the content of Fe3+ in Y polyhedra, and slightly increase with the increasing of the content of Fe2+ in Y polyhedra.
