| 摘 要： | 用X射线衍射外推函数法测定NaY超稳分子筛的晶胞参数，用^29Si、^27Al固体NMR方法测定分子筛骨架中的硅铝比，提出了NaY超稳分子筛硅铝比与晶胞参数关联的经验公式。通过测定分子筛的晶胞参数即可得到NaY超稳分子筛的硅铝比。该方法测得的NaY超稳分子筛硅铝比，比通常采用的化学分析方法省时、简便、重复性好。

| Abstract: | The Si/Al ratio of NaY molecular sieve was determined by an empirical formula of lattice constant obtained by extension function method of X-ray diffraction and framework Si/Al ratio of NaY molecular sieve determined by solid nuclear magnetic resonant spectrum method.The method is simpler,more convenient and better repeatable than the traditional used chemical analysis method. |
