【摘要】 量子同一性问题指的是量子力学中可以观测微观粒子数却在事实上完全无法区分各个粒子的问题,人们通常认为这意味着微观粒子个体性的丧失。巴西逻辑学家da Costa认为,经典逻辑的同一性原则与量子力学之间是不协调的,因此需要建立合适的禁自返逻辑(non-reflexive logic)来限制或取缔经典逻辑中的等词。在建立禁自返逻辑并利用它对量子同一性问题做出解释的同时,da Costa及相关学者又讨论了由此产生的语义学和本体论的问题。更多还原

【Abstract】 The problem of quantum identity lies in the fact that though the number of identical particles can be observed without difficulty,there is no way distinguishing such particles. This kind of phenomenon is often ascribed to the loss of the identity of sub-atomic particles. According to Newton da Costa,the Brazilian logician,the classical principle of identity is irreconcilable with quantum mechanics,as a result,appropriate non-reflexive logic need to be established to restrict and forbidden the equivalent words in the classical logic. In this article,the non-reflexive logical explanation of quantum identity is introduced,so is the discussion of the related semantic problem and the quantum identity.更多还原
