我们证明了n方纯态的局部酉等价与它们的（n−1）方约简密度矩阵的局部酉等价是一致的。作为一个应用，我们得到了一类三边纯量值的局部不变量。
We present that the local unitary equivalence of n-party pure states is consistent with that of their (n − 1)-party reduced density matrices. As an application, we obtain the local invariants for a class of tripartite pure qudits.
