The significance of the Niggli reduced cell is in its uniqueness and in the possibility that it can be used for determining Bravais lattice .

Niggli约化胞的唯一性使其能应用于确定晶体的Bravais点阵。

A new classification on the reduced cell and the criteria corresponding to the reducing treatment has been developed , and the relationships between the symmetry reduced cell and Bravais lattice are also given in the present paper .

为此，提出了一种新的约化胞分类法及其约化处理的判据，并给出了对称约化胞与Bravais点阵之间的对应关系。

The Reducing treatment of primitive cells is an important process to reconstruct the lattice and to determine the Bravais lattice of unknown crystals . The errors of the data used for reconstruction , which come from the measurement and calculations , usually make the reducing treatment uncertain and difficult .

初基胞约化处理是重构点阵和确定未知晶体Bravais点阵的一个重要环节，原始数据的测量误差和计算引入的积累误差给初基胞约化处理造成困难和不确定性。
