摘　　要：Ｎｉｇｇｌｉ约化胞的唯一性使其能应用于确定晶体的Ｂｒａｖａｉｓ点阵。本文在Ｎｉｇｇｌｉ约化条件的基础上，讨论了Ｎｉｇｇｌｉ约化胞到Ｂｒａｖａｉｓ点阵的转换关系，通过电子衍射方法，介绍了Ｎｉｇｇｌｉ约化胞在确定未知晶体Ｂｒａｖａｉｓ点阵中的应用。The significance of the Niggli reduced cell is in its uniqueness and in the possibility that it can be used for determining Bravais lattice.The transfomation from the Niggli cell to Bravais cell has been derived and are presented based on the introduction of Niggli reduced conditions,by means of selected- area electron diffraction,the application of the Niggli reduced cell in the determination of Bravais lattice of unknown crystal is given in this paper.
