摘　　要：全国高中生化学竞赛试题十分重视晶体结构的考查，以填隙的视角认识晶体结构有助于竞赛选手正确理解某些晶胞的结构特点；堆积球中空隙的形状、位置和分布特征对认识晶体的结构和性质均十分重要。Crystal structure is highlighted in National Chemistry Contest of senior high school students. Learning crystal structure in interstitial view helps the contestants to understand correctly the features of some crystal cells. As to the crystal structure and its properties, it＇s important to understand the shape, location and distribution of the interstices in the packing balls.

关 键 词：化学竞赛试题 晶体结构 填隙 晶体空隙
