I argue that a particle ontology naturally emerges from the basic dynamical equations of non-relativistic quantum mechanics, when the quantum continuity equation is realistically interpreted. This was recognized by J.J. Sakurai in his famous textbook “Modern Quantum Mechanics”, and then dismissed on the basis of the Heisenberg position–momentum uncertainty principle. In this paper, I show that the reasons of this rejection are based on a misunderstanding of the physical import of the uncertainty principle. As a consequence, a particle ontology can be derived from the quantum formalism without the need of additional ad hoc assumptions, and therefore it cannot be regarded as “extra-structure”.

我认为，当现实地解释量子连续性方程时，粒子本体论自然会从非相对论量子力学的基本动力学方程式中出现。樱井JJ在他著名的教科书“现代量子力学”中对此予以认可，然后根据海森堡位置-动量不确定性原理予以驳回。在本文中，我证明了这种拒绝的原因是基于对不确定性原理的物理意义的误解。结果，粒子本体可以从量子形式学派生而无需额外的特殊假设，因此不能将其视为“额外结构”。
