Einstein-Podolsky-Rosen (EPR) steering is very important quantum correlation of a composite quantum system. It is an intermediate type of nonlocal correlation between entanglement and Bell nonlocality. In this paper, based on introducing definitions and characterizations of EPR steering, some EPR steering inequalities are derived. With these inequalities, the steerability of the maximally entangled state is checked and some conditions for the steerability of the X -states are obtained.
爱因斯坦 - 波多尔斯基 - 罗森（EPR）引导是复合量子系统中非常重要的量子关联。它是纠缠与贝尔非定域性之间的一种中间类型的非定域关联。本文在介绍EPR引导的定义和特征的基础上，推导了一些EPR引导不等式。利用这些不等式，检验了最大纠缠态的可引导性，并得到了X态可引导性的一些条件。
