In any quantum mechanical ‎representation, the real part of the wave function ‎‎represents the space wave and the imaginary ‎part represents the time wave, and they are the space-time itself. Time wave is ‎‎not limited by ‎space and dominates the nonlocality and integrity of a quantum. Matter wave is a four-‎dimensional space-time ‎‎wave, and the basic unit of vacuum is a four-dimensional space-time ‎element stationary relative to the observer. The essence ‎‎of quantum measurement or interaction is ‎that a conjugate condensation equivalent to that determined by inner product ‎‎operation occurs ‎between Space-time waves. Particle property is only the localization effect of quantum global ‎collapse when ‎‎quantum position measurement or equivalent interaction is made.‎ 09 2022 60 75 10.55672/hij2022pp60-75 https://www.hscience.org/index.php/hij/article/view/44
