We studied several issues associated with experiments designed for testing nonlocality of quantum mechanics based on elementary particles including mesons. The problems for establishing quantum correlations due to the indistinguishablity of particles and their passive nature of decays were analyzed. We proposed a novel set of measures which is useful to characterize the entanglement of many particle states (such as GHZ and W). The intrinsic relative nature of entanglement with respect to measurement setups was also made transparent in our treatment of correlations.

我们研究了基于基本粒子（包括介子）的量子力学非定域性实验中的几个问题。分析了由于粒子的不相容性和衰变的被动性而导致的建立量子关联的问题。我们提出了一组新的度量，这是有用的描述许多粒子态（如GHZ和W）的纠缠。在我们处理相关性时，纠缠与测量设置的内在相对性质也变得透明。
