摘　　要：通过透射电子显微镜(TEM)对M1型阿利特进行研究。分别基于伪六方亚晶胞和M1超晶胞对选区电子衍射(SAED)花样和高分辨透射电子显微(HRTEM)像进行分析,确立伪六方亚晶胞和M1超晶胞之间的取向关系,即:(600)M1、(020)M1和(002)M1分别相当于(ī08)H、(ī20)H和(ī02)H,[100]M1∥[211]H、[010]M1∥[010]H以及[001]M1∥[■ī]H,同时还提出了两者之间的转换矩阵。由超结构产生的衍射斑点方向平行于[2■7]H*/[9■■]M1*,具有一维非公度调制特征。调制结构在HRTEM像中以波状条纹衬度的形式展现并平行于(2■7)H/(9■■)M1,条纹间距为1.25 nm。A M1 modification of alite was investigated using transmission electron microscopy（TEM）.Selected area electron diffraction（SAED） patterns and high resolution transmission electron microscopy（HRTEM） images were analyzed based on pseudo-hexagonal subcell and M1 supercell,respectively.The orientation relations between the two cells were established that（600）M1,（020）M1 and（002）M1 were equivalent to（ī08）H,（ī20）H and（ī02）H,[110]M1∥[211]H,[010]M1∥[010]H and [010]M1∥[■ī]H.The corresponding conversion matrix was also proposed.Reflections caused by the superstructure occurred along the direction parallel to （2■7）H＊/（9■■）M1＊ with a character of one-dimensional incommensurate type.The modulated structure could be observed on a HRTEM image as wavy contrast streak parallel to （2■7）H/（9■■）M1 with fringe spacing of 1.25 nm.
