作为对一组态的非定域性的研究，我们着重研究了在任意素维系统中，特别是对于正交最大纠缠态的非定域性，即局域复制和局域鉴别。其结果是，对于这样一个集合，我们完全确定的本地copiability的特点，并表明，本地复制比本地歧视更困难。
We focus on the nonlocality concerning local copying and local discrimination, especially for a set of orthogonal maximally entangled states in any prime dimensional system, as a study of nonlocality of a set of states. As a result, for such a set, we completely characterize deterministic local copiability and show that local copying is more difficult than local discrimination.
