The main focus of this paper is on the notion of transtemporal (diachronic) identity applied to quantum particles. I pose the question of how the symmetrization postulate with respect to instantaneous states of particles of the same type affects the possibility of identifying interacting particles before and after their interaction. The answer to this question turns out to be contingent upon the choice between two available conceptions of synchronic individuation of quantum particles that I call the orthodox and heterodox approaches. I argue that the heterodox approach offers a better explanation of the known experimental facts regarding particle interactions, and I probe deeper the concepts of synchronic and diachronic identity emerging from this approach.

基本粒子的同步和历时身份

本文的主要重点是应用于量子粒子的跨时（历时）恒等的概念。我提出一个问题，即关于相同类型粒子的瞬时状态的对称化如何影响在相互作用之前和之后识别相互作用粒子的可能性。这个问题的答案最终取决于在我称之为正统方法和异质方法的两个可行的量子粒子同步个体化概念之间进行选择。我认为异质混合方法可以更好地解释有关粒子相互作用的已知实验事实，并且我会更深入地探讨这种方法中出现的共时性和历时性的概念。
